TITLE:
Xoops Cross-Site Scripting and SQL Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA37920

VERIFY ADVISORY:
http://secunia.com/advisories/37920/

DESCRIPTION:
Stefano Angaran has discovered two vulnerabilities in Xoops, which
can be exploited by malicious people to conduct cross-site scripting
attacks and by malicious users to conduct SQL injection attacks.

1) Input passed to the "op" parameter in modules/pm/readpmsg.php 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.

Successful exploitation requires that the Private Messaging module is
installed.

2) Input passed to the "not_list" parameter in
include/notification_update.php via third-party modules (e.g. News)
is not properly sanitised before being used in SQL queries. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

The vulnerabilities are confirmed in version 2.4.2. Prior versions
may also be affected.

SOLUTION:
Update to version 2.4.3.

PROVIDED AND/OR DISCOVERED BY:
Stefano Angaran, reported via Secunia.
