CVE-2025-36135Network attack vector

Credential disclosure via authenticated Web UI script injection

Published Nov 7, 2025 · Updated Nov 7, 2025

Cross-site scripting in IBM Sterling B2B Integrator and IBM Sterling File Gateway allows remote authenticated users to disclose credentials. The Web UI renders attacker-supplied JavaScript in a trusted session, but IBM has not disclosed the affected parameter or code path that fails to neutralize the input. An authenticated user must introduce the payload, and another user must interact with the affected UI content for script execution and credential disclosure.
