TITLE:
SquirrelMail Malformed HTML Mail Message Script Insertion

SECUNIA ADVISORY ID:
SA32143

VERIFY ADVISORY:
http://secunia.com/advisories/32143/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
SquirrelMail 1.x
http://secunia.com/advisories/product/288/

DESCRIPTION:
Ivan Markovic has discovered a vulnerability in SquirrelMail, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed as HTML parts of e-mail messages is not properly
sanitised for malformed HTML before being viewed. This can be
exploited to inject arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when a malicious e-mail message is opened.

Successful exploitation requires that "Show HTML Version by Default"
is enabled in "Options -> Display Preferences".

The vulnerability is confirmed in version 1.4.16 and reported in
version 1.4.15. Prior versions may also be affected.

SOLUTION:
Do not open untrusted e-mail messages.

The vendor will release a fixed version later today.

PROVIDED AND/OR DISCOVERED BY:
