TITLE:
SquirrelMail Multiple Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA23195

VERIFY ADVISORY:
http://secunia.com/advisories/23195/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

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

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

1) Input passed to certain parameters in webmail.php and compose.php
in the "draft", "compose", and "mailto" functionality is not 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.

2) Input validation errors exist in the magicHTML filter when
sanitising HTML mails. This can be exploited to insert arbitrary HTML
and script code, which is executed in a user's browser session in
context of an affected site when the malicious data is viewed.

Successful exploitation of some of these errors require that the
target user runs Microsoft Internet Explorer.

The vulnerabilities are reported in versions before 1.4.9a.

SOLUTION:
Update to version 1.4.9a.
