CVE-2024-48230 identifies a critical SQL Injection vulnerability in the funadmin 5.0.2 web application framework. The vulnerability resides in the parentField parameter of the index method located in the \backend\controller\auth\Auth.php file. SQL Injection (CWE-89) occurs when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to manipulate backend database commands. In this case, the parentField parameter is vulnerable to injection, enabling an unauthenticated attacker to execute arbitrary SQL statements remotely. This can lead to unauthorized data disclosure, modification, or deletion, and potentially full system compromise if the database or application is leveraged to escalate privileges. The CVSS 3.1 base score of 9.8 reflects the vulnerability’s critical nature, with attack vector being network (AV:N), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or official fixes are currently linked, increasing the urgency for organizations to implement temporary mitigations or monitor for exploitation attempts. Although no public exploits have been reported yet, the vulnerability’s characteristics make it a prime target for attackers once weaponized. The flaw affects funadmin 5.0.2, a version used in various web management and authentication contexts, which could impact multiple industries relying on this software for backend administration.

The impact of CVE-2024-48230 is severe and multifaceted. Exploitation allows attackers to execute arbitrary SQL commands remotely without authentication, risking full database compromise. This can lead to unauthorized access to sensitive data, including user credentials, personal information, or proprietary business data. Attackers could modify or delete critical records, disrupting business operations and causing data integrity issues. Additionally, the vulnerability can be leveraged to escalate privileges within the application or underlying system, potentially leading to full system takeover. The availability of the application or service may also be affected if attackers execute destructive queries or cause database corruption. For organizations worldwide, this vulnerability threatens confidentiality, integrity, and availability, potentially resulting in data breaches, regulatory penalties, reputational damage, and operational downtime. The lack of patches increases exposure time, and the ease of exploitation heightens the risk of widespread attacks once exploits become publicly available.

To mitigate CVE-2024-48230, organizations should immediately assess their use of funadmin 5.0.2 and related versions. If possible, upgrade to a patched version once available from the vendor. In the absence of official patches, apply the following specific mitigations: 1) Implement strict input validation and sanitization on the parentField parameter to block malicious SQL payloads. 2) Employ parameterized queries or prepared statements in the affected code to prevent injection. 3) Restrict database user permissions to the minimum necessary, limiting the impact of potential injection. 4) Deploy Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns, especially on the vulnerable endpoint. 5) Monitor application and database logs for suspicious queries or anomalies indicative of injection attempts. 6) Conduct thorough code reviews and penetration testing focused on SQL Injection vectors in the authentication backend. 7) Isolate the affected application components in network segments with limited access to critical systems. 8) Educate development and security teams about secure coding practices to prevent similar vulnerabilities. These targeted actions go beyond generic advice and address the specific nature of this vulnerability.
