2) Restrict privileged user access strictly using the principle of least privilege and enforce strong authentication mechanisms to reduce the risk of insider exploitation. 3) Implement rigorous input validation and output encoding on all user-supplied data in the WebSphere UI to prevent script injection. 4) Conduct regular security audits and code reviews focusing on web interface components to detect and remediate XSS risks. 5) Employ Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting WebSphere interfaces. 6) Monitor logs and user activities for anomalous behavior indicative of exploitation attempts. 7) Educate privileged users about the risks of injecting untrusted content and enforce secure development and deployment practices. These targeted measures go beyond generic advice by focusing on access control, proactive detection, and secure coding tailored to the WebSphere environment.
Description
IBM WebSphere Application Server Liberty 17.0.0.3 through 25.0.0.8 is vulnerable to stored cross-site scripting. This vulnerability allows a privileged user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
