+-------------+
| 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.
