Cisco AnyConnect Secure Mobility Client 3.x < 3.1.11004.0 / 4.x < 4.1.6020.0 Privilege Escalation

high Nessus Plugin ID 86302

Language:

Synopsis

The remote host is affected by a privilege escalation vulnerability.

Description

The Cisco AnyConnect Secure Mobility Client installed on the remote host is version 3.x prior to 3.1.11004.0 or 4.x prior to 4.1.6020.0.
It is, therefore, affected by an untrusted search path flaw in the CMainThread::launchDownloader method due to a failure to check the path to the downloader application and associated DLL files. An authenticated, local attacker can exploit this, via running the downloader application from outside its expected location and providing crafted DLLs, to execute arbitrary commands on the host with privileges equivalent to the SYSTEM account.

Note that this vulnerability resulted from an incomplete fix for CVE-2015-4211.

Solution

Upgrade to Cisco AnyConnect Secure Mobility Client version 3.1.11004.0 / 4.1.6020.0 or later.
