An issue was discovered in K7 Ultimate Security 17.0.2045. A Local Privilege Escalation (LPE) vulnerability in the K7 Ultimate Security antivirus can be exploited by a local unprivileged user on default installations of the product. Insecure access to a named pipe allows unprivileged users to edit any registry key, leading to a full compromise as SYSTEM.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
