high Nessus Plugin ID 84431

Synopsis

The remote host contains an antivirus application that is affected by a local privilege escalation vulnerability.

Description

The remote Windows host has a version of AVG Internet Security installed that is 2013.x prior to 2013.3495 or 2015.x prior to 2015.5557. It is, therefore, affected by a local privilege escalation vulnerability due to a flaw in the TDI driver (avgtdix.sys) that occurs when handling 0x830020f8 IOCTL calls. A local attacker can exploit this, via a crafted 0x830020f8 IOCTL call, to write controlled data to an arbitrary memory location, resulting in arbitrary code execution with kernel-level privileges.

Solution

Upgrade to AVG Internet Security version 2013.3495 / 2015.5557 or later.
