CVE-2023-29145

Local arbitrary code execution via library allowlist bypass

Published Jun 30, 2023 · Updated Nov 26, 2024

Improper library whitelisting in Malwarebytes EDR 1.0.11 for Linux allows local users to execute arbitrary code through loaded libraries. The Linux driver trusts an allowed executable without validating libraries introduced through LD_LIBRARY_PATH, LD_PRELOAD, or a debugger. Exploitation requires low-privileged local access and bypasses the EDR approval boundary, allowing attacker-controlled library code to run.
