TITLE:
IMP Script Insertion and Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA24541

VERIFY ADVISORY:
http://secunia.com/advisories/24541/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
IMP Webmail Client 4.x
http://secunia.com/product/6376/

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

1) An input validation error in the processing of mails in thread.php
where the "Subject" header is not properly sanitised before being
displayed can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site via a
specially crafted mail.

2) Input passed to the "edit_query" parameter and other unspecified
parameters in search.php is not properly sanitised before being
returned to a user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

Successful exploitation requires that the target user is logged in.

The vulnerabilities are reported in version 4.1.3. Prior versions may
also be affected.

SOLUTION:
Update to version 4.1.4.
