The vulnerability identified as CVE-2024-46212 affects the REDAXO CMS version 5.17.1 and specifically targets the backup/export functionality accessible through the /index.php?page=backup/export endpoint. This directory traversal vulnerability represents a critical security flaw that allows unauthorized attackers to access arbitrary files on the server filesystem. The issue stems from insufficient input validation and sanitization within the backup module, where user-supplied parameters are not properly filtered before being processed. Attackers can exploit this weakness by manipulating the page parameter to navigate through the directory structure and potentially retrieve sensitive files including configuration data, database credentials, or other system files that should remain protected. The vulnerability falls under the CWE-22 category for Improper Limitation of a Pathname to a Restricted Directory, which is a well-documented weakness in web application security. This flaw aligns with ATT&CK technique T1083 (File and Directory Discovery) as it enables adversaries to enumerate the file system structure and access restricted resources.
The operational impact of this vulnerability extends beyond simple information disclosure, as it can lead to complete system compromise when combined with other attack vectors. An attacker who successfully exploits this directory traversal flaw can access not only configuration files but potentially application source code, user data, and other sensitive resources stored on the server. The vulnerability is particularly concerning because it affects a core administrative function within the CMS, meaning that unauthorized access to the backup/export feature could provide attackers with the ability to extract critical system information or even download the entire application structure. This type of vulnerability is often leveraged in conjunction with other exploits to establish persistence or escalate privileges within the compromised environment, making it a significant threat to organizations relying on REDAXO CMS for their web presence.
Mitigation strategies for CVE-2024-46212 should include immediate patching of the affected REDAXO CMS version to the latest available release that addresses this directory traversal vulnerability. Organizations should also implement proper input validation and sanitization measures within their web applications, ensuring that all user-supplied parameters are strictly validated before being processed. Network-level protections such as web application firewalls and proper access controls should be implemented to restrict access to administrative endpoints. Additionally, regular security audits and penetration testing should be conducted to identify similar vulnerabilities within the application stack. The remediation process should involve comprehensive testing to ensure that the patch does not introduce regressions in functionality while also implementing proper logging and monitoring to detect potential exploitation attempts. Organizations should also consider implementing principle of least privilege access controls and regular security training for administrators to reduce the risk of successful exploitation through social engineering or credential compromise.
