SYSTEM code execution via symlink-driven file deletion
Published Jul 29, 2024 · Updated Aug 1, 2024
Link-following in cmdagent in Comodo Internet Security Pro 12.2.4.8032 allows local users to execute arbitrary code as SYSTEM. The privileged cmdagent executable follows a symbolic link supplied by a low-privileged process and deletes the link target instead of validating the resolved path. Low-privileged code execution on the Windows host is required, and deletion of a privileged file provides the path to SYSTEM execution.
