tag_summary = "ViewVC is prone to a cross-site scripting vulnerability because the
application fails to sufficiently sanitize user-supplied data.

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 and steal cookie-based authentication credentials. Other attacks
are also possible.

Versions prior to ViewVC 1.1.4 and 1.0.10 are vulnerable.";
