TITLE:
Anti-Keylogger Elite "AKEProtect.sys" IOCTL Handling Vulnerabilities

SECUNIA ADVISORY ID:
SA32634

VERIFY ADVISORY:
http://secunia.com/advisories/32634/

CRITICAL:
Less critical

IMPACT:
Privilege escalation, DoS

WHERE:
Local system

SOFTWARE:
Anti-Keylogger Elite 3.x
http://secunia.com/advisories/product/20455/

DESCRIPTION:
alex has discovered some vulnerabilities in Anti-Keylogger Elite,
which can be exploited by malicious, local users to cause a DoS
(Denial of Service) or to potentially gain escalated privileges.

The vulnerabilities are caused due to the "AKEProtect.sys" driver
improperly validating parameters received via IOCTL codes 0x002224A4,
0x002224C0, and 0x002224CC. This can be exploited to cause a system
crash or potentially execute arbitrary code in kernel space.

Successful exploitation requires that the Anti-Keylogger Elite GUI is
not running.

The vulnerabilities are confirmed in version 3.3.3. Other versions
may also be affected.

SOLUTION:
Restrict local access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
alex, NT Internals
