CVE-2020-4311

Local code execution via DLL planting

Published Apr 23, 2020 · Updated Sep 16, 2024

Insufficient file permissions in IBM Tivoli Monitoring 6.3.0 through fix pack 7 allow local users to execute arbitrary code via DLL planting. Installation directories permit non-privileged file placement, so a crafted DLL is loaded from the same directory during normal component execution. The attacker needs local access; successful loading provides code execution with the privileges of the Tivoli Monitoring process and can affect confidentiality, integrity, and availability.
