CVE-2023-50307Network attack vector

Credential disclosure via Web UI script injection

Published Apr 12, 2024 · Updated Aug 2, 2024

Cross-site scripting in IBM Sterling B2B Integrator allows remote authenticated users to expose credentials through the Web UI. IBM has not identified the vulnerable field or code locus; the Web UI accepts attacker-supplied JavaScript and renders it without effective neutralization. Exploitation requires low-privileged access and interaction by a user in a trusted session, where the script can alter interface behavior and expose credentials.
