IMPACT:

WHERE:

SOFTWARE:
ProjectForum 4.x

DESCRIPTION:
r0t has reported a vulnerability in ProjectForum, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "fwd" parameter in "/admin/adminsignin.html" and
the "originalpageid" parameter in "/[groupname]/admin/newpage.html"
isn't properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

The vulnerability has been reported in version 4.7.0 and prior. Other
versions may also be affected.

Note: It is also reportedly possible to cause a DoS (Denial of
Service) by sending certain requests to the "pageid" parameter in
"/admin/versions.html".

SOLUTION:
Filter malicious characters and character sequences in a HTTP proxy.

PROVIDED AND/OR DISCOVERED BY:
