MantisBT Multiple Local File Include and Cross Site Scripting Vulnerabilities
MantisBT is prone to multiple local file-include and cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker can exploit the local file-include vulnerabilities using directory-traversal strings to view and execute local files within the context of the webserver process. Information harvested may aid in further attacks.
The attacker may leverage the cross-site scripting issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.
MantisBT versions prior to 1.2.8 are vulnerable.
