+-------------+
| Description |
+-------------+
Multiple Panda Security products are vulnerable to local privilege escalation. As the USERS group has write permissions over the folder where the PSEvents.exe process is located, it is possible to execute malicious code as Local System.
+--------------+
| Exploitation |
+--------------+
“PSEvents.exe” is scheduled to be executed every hour with SYSTEM Privileges. When executed, it tries to locate a number of DLLs in its local directory to be loaded. However, some of these DLLs don’t exist.
The DACLs of the directory that contains the “PSEvents.exe” executable allow a user in the USERS group to create files in that directory. A malicious user can exploit this vulnerability by creating a malicious DLL file in that directory and name it as one of the missing DLLs. After one hour, the “PSEvents.exe” process will start and load our malicious DLL
The same method can be used to exploit other executables (PSDevice.exe and PSProfiler.exe) located in Panda’s Downloads directory.
