TITLE:
vBulletin Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA16873

VERIFY ADVISORY:
http://secunia.com/advisories/16873/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
vBulletin 3.x
http://secunia.com/product/3212/
vBulletin 2.x
http://secunia.com/product/538/

DESCRIPTION:
Thomas Waldegger has reported some vulnerabilities in vBulletin,
which can be exploited by malicious users to conduct SQL injection
attacks and potentially compromise a vulnerable system, and by
malicious people to conduct cross-site scripting attacks.

1) Some input passed in the administration section isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in an administrator's browser
session in context of an affected site.

2) Some input passed in the administration section isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires administrative privileges.

3) The problem is that it is possible to upload arbitrary files
inside the web root via the avatars/icons/smileys upload
functionality. This can e.g. be exploited to upload and execute
arbitrary PHP scripts.

Successful exploitation requires administrative privileges.

The vulnerabilities have been reported in version 3.0.8 and prior.
Other versions may also be affected.

SOLUTION:
Some of the vulnerabilities have reportedly been fixed in version
3.0.9.
