CVE-2024-31903

Adjacent-network code execution via untrusted deserialization

Published Jan 22, 2025 · Updated Feb 12, 2025

Untrusted deserialization in IBM Sterling B2B Integrator Standard Edition allows attackers on the local network to execute arbitrary code. IBM has not disclosed the deserialization entry point, serialized format, or code path that processes attacker-controlled data. Network adjacency is required, but authentication and user interaction are not; successful exploitation runs arbitrary code with the service's privileges.
