TITLE:
DevalCMS Cross-Site Scripting and Code Execution Vulnerabilities

SECUNIA ADVISORY ID:
SA31776

VERIFY ADVISORY:
http://secunia.com/advisories/31776/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
devalcms 1.x
http://secunia.com/advisories/product/19079/

DESCRIPTION:
IRCRASH has discovered some vulnerabilities in DevalCMS, which can be
exploited to conduct cross-site scripting attacks and compromise a
vulnerable user's system.

1) Input passed to the "currentpath" parameter in index.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 the context of an affected site.

2) Input passed in HTTP headers "Referer" and "User-Agent", and e.g
the "gv_folder_data" parameter to /modules/tool/hitcounter.php is not
properly sanitised before being used to write data to files. This can
be exploited write arbitrary data to certain files and execute
arbitrary PHP code.

Successful exploitation requires that "register_globals" is enabled.

These vulnerabilities are confirmed in version 1.4.a. Other versions
may also be affected.

SOLUTION:
Edit the source to ensure that input is properly sanitised.
