ContentNow Multiple Vulnerabilities
Release Date: 2006-11-13 Last Update: 2006-11-21 Views: 7,087
Secunia Advisory SA22805
Where:
From remote
Impact:
Cross Site Scripting, Manipulation of data, Exposure of sensitive information, System access,
Solution Status:
Partial Fix
CVE Reference(s):
No CVE references.
Description
r0ut3r and Timq have discovered some vulnerabilities in ContentNow, which can be exploited by malicious people to disclose certain sensitive information, perform certain actions with escalated privileges, to compromise a vulnerable system, or to perform cross-site scripting attacks.
1) Input passed to the "lang" parameter in multiple files is not properly verified before it is used to include files. This can be exploited to include arbitrary files from local resources.
Examples:
http://[host]/cn/edit.php?lang=[file]
http://[host]/cn/image.php?lang=[file]
http://[host]/cn/upload.php?lang=[file]
NOTE: More files may potentially be affected.
2) It is possible to access certain scripts in the "cn" directory without proper authentication. This can e.g. be exploited to edit, view or delete files or to upload and execute arbitrary PHP code.
3) Input to the "path" parameter in cn/upload.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 context of an affected site.
The vulnerabilities are confirmed in version 1.30. Other versions may also be affected.
Solution:
Grant only trusted people access to the "cn" directory (e.g. with an ".htaccess" file) and edit the source code to ensure that input is properly sanitised.
