TITLE:
XOOPS Script Insertion and Local File Inclusion

SECUNIA ADVISORY ID:
SA33048

VERIFY ADVISORY:
http://secunia.com/advisories/33048/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information

WHERE:
>From remote

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

DESCRIPTION:
Some vulnerabilities have been reported in XOOPS, which can be
exploited by malicious users to conduct script insertion attacks and
malicious people to disclose sensitive information.

1) Input passed to the "xoopsConfig[language]" parameter in
xoops_lib/modules/protector/blocks.php and
xoops_lib/modules/protector/main.php is not properly verified before
being used to include files. This can be exploited to include
arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed via the "url" BBcode tag when sending a private
message 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 message is viewed.

Vulnerability #1 is reported in XOOPS 2.3.x prior to 2.3.2a and
vulnerability #2 is reported in XOOPS 2.3.x prior to 2.3.2b. XOOPS
versions 2.0 and 2.2 are reportedly not affected.

SOLUTION:
Update to version 2.3.2b.
