Description:
Alexandr Polyakov and Stas Svistunovich have discovered a vulnerability in phpCMS, which can be exploited by malicious people to disclose sensitive information.
Input passed to the "file" parameter in parser/parser.php is not properly verified before being used. This can be exploited to disclose the content of files (e.g. include/default.php) within the phpCMS root folder or it's subdirectories.
Note: Reportedly, it's possible to disclose arbitrary files via directory traversal attacks on Windows systems.
The vulnerability is confirmed in version 1.22. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified.
Provided and/or discovered by:
Alexandr Polyakov and Stas Svistunovich, Digital Security Research Group
