Summary
Mantis is prone to multiple HTML-injection vulnerabilities because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie- based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
Versions prior to Mantis 1.2.3 vulnerable.
Solution
The vendor released an update. Please see the references for more information.
