* Date of Release: 05/04/2016
* Affected Products: Multiple
* Affected Version: Panda Endpoint Administration Agent < v7.50.00
* Fixed Version: Panda Endpoint Administration Agent v7.50.00


Description:
Panda Endpoint Administration Agent v7.30.2 allows a local attacker to elevate 
his privileges from any account type (Guest included) and execute code as 
SYSTEM, thus completely compromising the affected host.


Affected Products:

Any Panda Security For Business products for Windows using this Agent service 
are vulnerable.


Technical Details:

Upon installing some Panda Security for Business products for Windows, such as 
Panda Endpoint Protection/Plus, a service named as 'Panda Endpoint 
Administration Agent' is installed in the host. This service runs  under the 
SYSTEM account. However, due to weak ACLs set to the installation directory 
("C:\Program Files\Panda Security\WaAgent") of this application and its 
subdirectories, any user can modify or overwrite any executable module (dynamic 
link libraries and executables) installed in those directories.


Impact:

A local attacker can elevate his privileges from any user account and execute 
code as SYSTEM.
