CVE-2024-31673 identifies a critical SQL Injection vulnerability in Kliqqi-CMS version 2.0.2, located in the load_data.php file via the userid parameter. SQL Injection (CWE-89) occurs when untrusted input is improperly sanitized before being included in SQL queries, allowing attackers to manipulate backend database commands. In this case, the userid parameter is not properly validated or escaped, enabling remote attackers to inject malicious SQL statements. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Successful exploitation can lead to full compromise of the database, including unauthorized data disclosure, data modification, or deletion, and potentially remote code execution if the database or application allows it. The vulnerability was reserved on April 5, 2024, and published on May 3, 2024. No patches or fixes have been linked yet, and no known exploits are publicly reported, but the critical severity and ease of exploitation make it a high-priority issue for affected users. Kliqqi-CMS is an open-source content management system, and its user base is relatively niche but can include websites relying on it for content publishing and management.

The impact of CVE-2024-31673 is severe for organizations using Kliqqi-CMS 2.0.2. Exploitation can lead to complete compromise of the backend database, resulting in unauthorized access to sensitive information, data tampering, or deletion. This can cause significant data breaches, loss of data integrity, and disruption of service availability. Attackers could leverage this vulnerability to escalate attacks, pivot within networks, or deploy further malware. Organizations relying on Kliqqi-CMS for public-facing websites or internal content management risk reputational damage, regulatory penalties, and operational downtime. Given the vulnerability requires no authentication and no user interaction, it can be exploited by automated tools or attackers scanning for vulnerable instances, increasing the likelihood of widespread attacks once exploit code becomes available.

To mitigate CVE-2024-31673, organizations should immediately audit their use of Kliqqi-CMS and identify any instances running version 2.0.2. Since no official patch is currently linked, users should consider the following specific actions: 1) Implement Web Application Firewall (WAF) rules to detect and block SQL Injection attempts targeting the userid parameter in load_data.php. 2) Apply input validation and sanitization at the application level, ensuring all user-supplied input is properly escaped or parameterized in SQL queries. 3) Restrict database user permissions to the minimum necessary to limit potential damage from injection attacks. 4) Monitor logs for suspicious activity related to load_data.php and userid parameter usage. 5) If possible, upgrade to a newer, patched version of Kliqqi-CMS once available or consider alternative CMS platforms with active security support. 6) Conduct regular security assessments and penetration tests focusing on injection flaws. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable component and parameter.
