Synopsis :

The remote web server contains a CGI application that if affected by a
cross-site scripting vulnerability.

Description :

The version of Bugzilla installed on the remote host is affected by a
cross-site scripting vulnerability because it fails to properly sanitize
user-supplied input to the 'id' parameter of the 'show_bug.cgi' script.
An attacker may be able to leverage this to inject arbitrary HTML and
script code into a user's browser to be executed within the security
context of the affected site.

Note that the install is also likely to be affected by an information
disclosure vulnerability
however, Nessus has not tested for this.
