CVE-2024-53908 is a severe SQL injection vulnerability identified in Django's handling of JSON field lookups specifically when interfacing with Oracle databases. The issue exists in Django versions before 5.1.4, 5.0.10, and 4.2.17. The vulnerability stems from the direct use of the django.db.models.fields.json.HasKey lookup, which, when supplied with untrusted input as the lhs value, fails to properly sanitize or parameterize the input. This improper handling allows an attacker to craft malicious input that can alter the intended SQL query, leading to SQL injection (CWE-89). Notably, applications that use the jsonfield.has_key lookup via the double underscore (__) syntax are not vulnerable, indicating the flaw is limited to direct usage of HasKey. The vulnerability is critical because it allows remote attackers to execute arbitrary SQL commands without authentication or user interaction, potentially compromising the entire database's confidentiality, integrity, and availability. The CVSS 3.1 score of 9.8 reflects the ease of exploitation and the severe impact. Although no known exploits have been reported in the wild yet, the vulnerability's nature and severity make it a high-priority risk for organizations using affected Django versions with Oracle backends. The issue was publicly disclosed on December 6, 2024, and patches have been released in Django 5.1.4, 5.0.10, and 4.2.17 to address the problem.

The SQL injection vulnerability in Django's HasKey lookup on Oracle databases can have devastating impacts on organizations worldwide. Exploitation allows attackers to execute arbitrary SQL commands remotely without authentication, leading to full database compromise. This can result in unauthorized data disclosure, data modification or deletion, and potential disruption of application availability. Organizations relying on Django with Oracle backends for critical applications risk severe data breaches, loss of customer trust, regulatory penalties, and operational downtime. The vulnerability's ease of exploitation and high severity make it a prime target for attackers seeking to leverage SQL injection for lateral movement, data exfiltration, or ransomware deployment. Given Django's widespread use in web applications globally, especially in enterprise environments that may use Oracle databases, the impact is broad and significant.

To mitigate CVE-2024-53908, organizations should immediately upgrade Django to versions 5.1.4, 5.0.10, or 4.2.17 or later, where the vulnerability is patched. Avoid direct usage of django.db.models.fields.json.HasKey lookup with untrusted input, especially when using Oracle databases. Instead, use the jsonfield.has_key lookup via the double underscore syntax, which is not vulnerable. Conduct thorough code reviews to identify and refactor any direct HasKey usage with dynamic or user-supplied data. Implement strict input validation and sanitization on all inputs that interact with database queries. Employ Web Application Firewalls (WAFs) with SQL injection detection rules tailored for Oracle SQL syntax to provide an additional layer of defense. Monitor application logs and database query logs for suspicious activity indicative of SQL injection attempts. Finally, maintain an incident response plan ready to address potential exploitation attempts promptly.
