TITLE:
XOOPS "mydirname" PHP Code Injection Vulnerability

SECUNIA ADVISORY ID:
SA33435

VERIFY ADVISORY:
http://secunia.com/advisories/33435/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Xoops 2.x
http://secunia.com/advisories/product/327/

DESCRIPTION:
athos has discovered a vulnerability in XOOPS, which can be exploited
by malicious people to compromise a vulnerable system.

Input passed to the "mydirname" parameter in
xoops_lib/modules/protector/oninstall.php,
xoops_lib/modules/protector/onupdate.php,
xoops_lib/modules/protector/notification.php, and
xoops_lib/modules/protector/onuninstall.php is not properly sanitised
before being used in an "eval()" statement. This can be exploited to
inject and execute arbitrary PHP code.

Successful exploitation requires that "register_globals" is enabled.

Note: The XOOPS installation also incorrectly sets the
"XOOPS_TRUST_PATH" configuration variable to a folder inside the web
root.

The vulnerability is confirmed in version 2.3.2b. Other versions may
also be affected.

SOLUTION:
Restrict web access to the affected files (e.g. via ".htaccess").

PROVIDED AND/OR DISCOVERED BY:
athos
