Impact:

Description


Rubén Santamarta has reported some vulnerabilities in CA Personal Firewall, which can be exploited by malicious, local users to gain escalated privileges.

The vulnerabilities are caused due to errors in the HIPS Core (KmxStart.sys) and HIPS Firewall (KmxFw.sys) drivers. This can be exploited to modify some implemented callbacks via certain privileged IOCTLs.

Successful exploitation allows execution of arbitrary code with Ring0 privileges.

The vulnerabilities are reported in version 6.5.4.10 of KmxStart.sys and version 6.5.4.31 of KmxFw.sys included in CA Personal Firewall 2007. Other versions and products may also be affected.


Solution:
Update the engine to version 1.0.176 or higher (available via automatic update).
