Vulnerability Note VU#613886

McAfee Managed Agent contains a denial-of-service (DoS) vulnerability

Original Release date: 04 Oct 2013 | Last revised: 04 Oct 2013

Overview

McAfee Managed Agent versions 4.5, 4.6, and possibly earlier versions contain a denial-of-service (DoS) vulnerability (CWE-400).

Description

CWE-400:Uncontrolled Resource Consumption ('Resource Exhaustion')

McAfee Managed Agent versions 4.5 and 4.6 contain a denial-of-service (DoS) vulnerability. McAfee Managed Agent runs a service on Windows workstations called "McAfee Framework Service" (FrameworkService.exe) which runs an HTTP server on the default TCP port 8081.

By sending a crafted request an attacker can remotely crash the Windows service. This can cause the McAfee software to temporarily stop updating or provide log data until the service is manually restarted.

Impact

An unauthenticated remote attacker may be able to cause a denial-of-service against the McAfee Managed Agent software.

Solution

McAfee has released a security bulletin with the details on obtaining the security hotfix for Managed Agent 4.5 Patch 3 and Managed Agent 4.6 Patch 3. McAfee Managed Agent versions 4.8 RTW and later are not affected. If applying the security hotfix is not possible, please consider the following workaround.

Accept connections only from the ePO server
Make sure that the "Accept connections only from the ePO server" option is enabled in the ePO Agent policy.
