Privilege Escalation in Panda Internet Security
Vendor: http://www.pandasecurity.com/
Vulnerability Type: Binary Planting Attack
Remote: No
Local: Yes
Discovered: 09 September 2012
Reported: 19 November 2012
Disclosed: 04 December 2012
VULNERABILITY DESCRIPTION:
As a result of an incorrect dynamic link library (DLL) loading in Panda Internet Security, an attacker with user level access to the machine can elevate his/her privileges to SYSTEM.
This can be accomplished by planting a malicious DLL file in a writable folder that is part of the system's %PATH% variable. The malicious DLL is loaded when the vulnerable Panda service or the system is restarted.
The following DLLs are insecurely loaded by Panda Internet Security 2013:
| Insecure DLL | Vulnerable Service |
| Pavshld.dll | PsCtrls.exe, PsImSvc.exe, PavFnSvr.exe, PskSvc.exe |
| ImFilter.dll2 | PsImSvc.exe |
| ImFilter.dll3 | PsImSvc.exe |
| ImFilter.dll4 | PsImSvc.exe |
In addition to the above DLLs, Panda Internet Security 2012 also loads ham.dll insecurely.
