CVE-2019-17099

Local code execution via untrusted DLL search

Published Jan 27, 2020 · Updated Sep 16, 2024

Untrusted DLL search in Bitdefender Endpoint Security Tools before 6.6.11.163 allows local users to execute arbitrary code. EPSecurityService.exe loads an attacker-controlled DLL from its search path without restricting resolution to a trusted directory. Exploitation requires high local privileges and user interaction; loaded code can read data and alter or interrupt the endpoint agent.
