TITLE:
phpwcms Cross-Site Scripting and Local File Inclusion

SECUNIA ADVISORY ID:
SA20239

VERIFY ADVISORY:
http://secunia.com/advisories/20239/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information, System
access

WHERE:
>From remote

SOFTWARE:
phpwcms 1.x
http://secunia.com/product/6129/

DESCRIPTION:
trueend5 has discovered a vulnerability in phpwcms, which potentially
can be exploited by malicious users to compromise a vulnerable system,
and by malicious people to conduct cross-site scripting attacks and
disclose potentially sensitive information.

1) Input passed to the "spaw_root" parameter in
"/include/inc_ext/spaw/spaw_control.class.php" is not properly
verified before being used to include files. This can be exploited to
include arbitrary files from local resources. It is reportedly
possible for an authenticated user to upload image files containing
PHP code as EXIF metadata into the "/picture/upload/" directory and
executing the code by including it.

Successful exploitation requires that "register_globals" is enabled
and "magic_quotes_gpc" is disabled.

2) Input passed to the "BL[be_cnt_plainhtml]" parameter in
"/include/inc_tmpl/content/cnt6.inc.php" and other template files 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 "register_globals" is enabled.

The vulnerabilities have been confirmed in version 1.2.6 and also
reported in 1.2.5-DEV. Other versions may also be affected.

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