VERIFY ADVISORY:
http://secunia.com/advisories/19492/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Bugzero 4.x
http://secunia.com/product/9117/

DESCRIPTION:
Some vulnerabilities have been discovered in Bugzero, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

1) Input passed to the "msg" parameter in various scripts (login.jsp,
main.jsp, and query.jsp) and the "entryId" parameter in edit.jsp is
not properly sanitised before being returned to users. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of a vulnerable site.

2) Input passed to the "projectId" parameter in edit.jsp and the
"error" parameter in error.jsp is not properly sanitised before being
returned in error messages to users. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of a vulnerable site.

The vulnerabilities have been confirmed in version 4.3.1-0158. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

Use another product.
