Argosoft Mail Server Cross-Site Scripting and Script Insertion

SECUNIA ADVISORY ID:
SA15100

VERIFY ADVISORY:
http://secunia.com/advisories/15100/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
ArGoSoft Mail Server 1.8.x
http://secunia.com/product/444/

DESCRIPTION:
ShineShadow has discovered two vulnerabilities in Argosoft Mail
Server, which can be exploited by malicious people to conduct
cross-site scripting and script insertion attacks.

1) Certain input passed in mails is not properly sanitised before
being used. 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 the malicious mail is viewed.

Example:
The "src" parameter in the "IMG" tag.

This is related to:
SA13571

2) Input passed to certain parameters in the user settings 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 a vulnerable site.

The vulnerabilities have been confirmed in version 1.8.7.6. Other
versions may also be affected.

SOLUTION:
Do not open untrusted mails and do not visit untrusted web sites
while being logged in.
