What is CVE-2011-10009?

S40 CMS version 0.4.2 contains a path traversal vulnerability that can be exploited through the index.php page handler. The vulnerability arises due to improper sanitization of the 'p' parameter, allowing attackers to traverse the filesystem and access arbitrary files beyond the web root directory. This exploit can be executed remotely without the need for authentication by appending traversal sequences or null bytes, thus bypassing file extension checks. This poses a significant risk as it enables unauthorized access to sensitive files, potentially leading to further exploitation of the affected system.
