The vulnerability identified as CVE-2007-3585 represents a critical remote file inclusion flaw in MyCMS version 0.9.8 and earlier systems. This issue resides within the games.php script which fails to properly validate or sanitize user input parameters before incorporating them into file operations. The vulnerability specifically manifests when the id parameter contains a URL that points to an external resource, enabling attackers to inject and execute malicious PHP code on the target server. This type of vulnerability falls under the broader category of insecure direct object references and improper input validation, which are commonly exploited in web application attacks.
The technical exploitation of this vulnerability occurs through the manipulation of the id parameter in the games.php script where the application directly includes or requires files based on user-supplied input without adequate sanitization. When an attacker supplies a malicious URL in the id parameter, the PHP interpreter processes this input as a file path and attempts to include the remote resource, thereby executing any PHP code contained within that remote file. This vulnerability is particularly dangerous because it allows for arbitrary code execution, which can lead to complete system compromise and unauthorized access to sensitive data.
From an operational impact perspective, this vulnerability creates significant security risks for organizations running affected MyCMS versions. Attackers can leverage this flaw to gain unauthorized access to the web server, potentially leading to data theft, system compromise, or further network infiltration. The vulnerability enables attackers to execute commands on the target system, deploy backdoors, or establish persistent access, making it a severe threat to the confidentiality, integrity, and availability of the affected systems. This type of vulnerability is particularly concerning in environments where the web application has elevated privileges and can access sensitive system resources.
Security mitigations for this vulnerability should focus on implementing proper input validation and sanitization techniques to prevent unauthorized file inclusion operations. Organizations should immediately upgrade to patched versions of MyCMS or apply the appropriate security patches that address this vulnerability. Input validation should include strict parameter filtering to ensure that only expected and safe values are accepted for the id parameter, with any external URL references being rejected or properly sanitized. Additionally, implementing proper access controls and restricting file inclusion operations to local resources only can significantly reduce the risk of exploitation. This vulnerability aligns with CWE-98 and CWE-22 categories, and represents a common attack vector that maps to techniques described in the MITRE ATT&CK framework under T1190 for exploitation of remote services and T1059 for command and scripting interpreters. Organizations should also implement web application firewalls and security monitoring to detect and prevent exploitation attempts targeting this specific vulnerability.
