Content2Web Lets Remote Users Inject SQL Commands, Conduct Cross-Site Scripting Attacks, and Include Local Files

SecurityTracker Alert ID: 1014900
SecurityTracker URL: http://securitytracker.com/id?1014900
CVE Reference: GENERIC-MAP-NOMATCH (Links to External Site)
Date: Sep 14 2005

Impact: Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information

Exploit Included: Yes

Version(s): 1.0.1

Description: LINUX from sosvulnerable.net reported a vulnerability in Content2Web. A remote user can execute arbitrary scripting code from the target system. A remote user can also inject SQL commands and conduct cross-site scripting attacks.

The software does not properly validate user-supplied input in the 'show' parameter. This can be exploited to execute PHP code, inject SQL commands, conduct cross-site scripting attacks, and determine the installation path.

A remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code files that reside on the target system. The PHP code, including operating system commands, will run with the privileges of the target web service.

A demonstration exploit URL is provided:

http://[target]/index.php?show=[file]&cat=news_archiv&start=1

[Editor's note: It is not clear if files from a remote location can be included or not.]

A remote user can supply a specially crafted parameter value to execute SQL commands on the underlying database.

A demonstration exploit URL is provided:

http://[target]/index.php?show=c2w_news%2Ephp&cat=news_archiv

A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Content2Web software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A demonstration exploit URL is provided:

http://[target]/index.php?show=%3C/textarea%3E%3Cscript%3Ealert(%27XSS
aka %27);%3C/script%3E&site=impressum

A remote user can supply the following type of URL to determine the installation path:

http://[target]/index.php?show=showme_full_ path_xD&start=1

Impact: A remote user can execute arbitrary PHP code and operating system commands from files residing on the target system with the privileges of the target web service.

A remote user can execute SQL commands on the underlying database.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Content2Web software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can determine the installation path.
