CVE-2020-28198Public exploit

Local code execution via oversized interactive identifier

Published May 6, 2021 · Updated Aug 4, 2024

Stack buffer overflow in IBM Tivoli Storage Manager 5.2.0.1 allows local users to execute code via an oversized interactive identifier. The dsmadmc.exe prompt places the id input in a fixed stack buffer without enforcing its 68-byte control-data boundary, so excess bytes overwrite EIP. Exploitation requires local interactive-mode input; length limits prevent the documented payload from reaching the overflow through batch or command-line arguments.
