K7 Antivirus Flaw Lets Attackers Gain SYSTEM-Level Privileges

A significant security vulnerability has been identified in the K7 Ultimate Security antivirus software, allowing attackers to obtain SYSTEM-level access on Windows computers.

A significant security vulnerability has been identified in the K7 Ultimate Security antivirus software, allowing attackers to obtain SYSTEM-level access on Windows computers.

The vulnerability, designated as CVE-2024-36424, permits low-privileged users to escalate their permissions, enabling full control over compromised systems.

K7 Ultimate Security utilizes named pipes for communication between software components. These pipes allow programs with limited permissions to request actions from programs with higher permissions.

Researchers discovered that the named pipe, K7TSMngrService1, used by K7, had insufficient access controls. This vulnerability allows any process to send crafted messages, prompting the SYSTEM-level service to perform unauthorized registry changes.

Exploitation can occur in two primary ways. Firstly, an attacker can disable antivirus protection by sending specific commands to the named pipe, including turning off real-time scanning or cloud protection. Secondly, full privilege escalation is achievable via Image File Execution Options (IFEO), allowing attackers to manipulate Windows registry keys that control program startup behavior.

K7 Computing released multiple patches to address the vulnerability. The initial patch included caller validation to verify which programs were sending commands. However, researchers bypassed this by injecting code into legitimate K7 processes.

Subsequent patches introduced process protection via the K7Sentry driver and expanded the protection list. Despite these measures, researchers exploited the vulnerability by using digitally signed K7 binaries not on the protected list.

This vulnerability affects K7 Ultimate Security version 17.0.2045 and potentially earlier versions. It is advised that organizations using K7 antivirus update to the latest version immediately.

The flaw highlights the risk of using antivirus software as an attack vector when security controls are insufficient. Security experts recommend antivirus vendors implement strict authentication for inter-process communication and avoid relying on process name verification for security decisions. Users should monitor systems for unusual registry changes or privilege escalations.

The disclosure of this vulnerability followed responsible reporting practices, providing the vendor with multiple opportunities to address the issue before public release.
