CVE-2020-4955

Elevated code execution via servlet parameters

Published Feb 15, 2021 · Updated Sep 17, 2024

Code injection in IBM Spectrum Protect Operations Center 7.1 and 8.1 allows remote authenticated users to run code via a servlet request. An unspecified servlet improperly validates crafted input parameters and uses them to load an attacker-supplied DLL with elevated privileges. Network adjacency and low-privileged access are required, and successful exploitation executes code with elevated privileges.
