Technical details
Cross-site scripting (XSS) vulnerability in IBM Concert's Web UI allows unauthenticated attackers to embed arbitrary JavaScript code. The attacker can craft malicious input that executes in the context of a victim's browser session with trusted authentication, leading to credential disclosure or session compromise. No authentication is required to craft the payload, though user interaction may be needed to trigger it.
