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.
