CVE-2023-38364Network attack vector

Credential disclosure via Web UI XSS

Published Nov 13, 2023 · Updated Aug 30, 2024

Cross-site scripting in IBM CICS TX Advanced 10.1 allows remote attackers to inject JavaScript in the Web UI and disclose credentials via trusted sessions. The Web UI renders attacker-controlled input without adequate neutralization, allowing script execution that changes page behavior. Exploitation requires a victim to load the affected content in a trusted session; the documented impact is credential disclosure and altered functionality, not service interruption.
