CVE-2025-3630Network attack vector

Credential disclosure via stored Web UI script

Published Jul 8, 2025 · Updated Aug 24, 2025

Stored XSS in IBM Sterling B2B Integrator and File Gateway allows remote authenticated users to disclose credentials via the Web UI. The Web UI stores and later renders attacker-supplied JavaScript, but IBM has not disclosed the affected input, handler, or missing output-encoding operation. An authenticated account can plant script that executes in a trusted session; affected releases are 6.0.0.0 through 6.1.2.6 and 6.2.0.0 through 6.2.0.4.
