An issue was discovered in Django affecting versions 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. This vulnerability allows remote attackers to inject SQL via the band index parameter in raster lookups on the `RasterField`, which is only implemented on PostGIS. Earlier unsupported Django series, such as 5.0.x, 4.1.x, and 3.2.x, were not evaluated and may also be affected. Django appreciates Tarek Nakkouch for reporting this issue.
The vulnerability has been assigned a CVSS score of 5.4, indicating a medium severity level. The risk to organizations includes potential unauthorized SQL command execution, which could lead to data exposure or manipulation if successfully exploited.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. Patches are available for affected versions, and it is crucial for organizations to ensure they are running updated software to prevent exploitation.
As of now, no public exploit has been confirmed, and the vulnerability is not listed as actively exploited in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should not become complacent, as the potential for exploitation exists.
Vulnerability Details
Django has classified this vulnerability under CWE-89, which relates to SQL injection issues. The full CVSS vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N, indicating that the attack vector is network-based, with low complexity and low privileges required to execute the attack.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input for the band index parameter in raster lookups. Since this functionality is specific to the PostGIS implementation of Django, it is critical to review how user-supplied data is processed in this context.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the system. The attack complexity is low, as it requires minimal effort to inject malicious SQL commands if the system is vulnerable.
No user interaction is required for exploitation, making it easier for an attacker to execute an attack. The confidentiality and integrity impacts are classified as low, indicating that sensitive data may be exposed or altered, but there is no impact on availability.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is heightened due to its nature, allowing remote attackers to exploit vulnerable systems. Organizations using affected Django versions should assess their deployment environment and determine the potential blast radius of an exploit.
Risk to organizations includes unauthorized access to sensitive data and potential data corruption. Given the CVSS score of 5.4, organizations should address this vulnerability in their priority patch cycle to minimize exposure.
Although the vulnerability is currently not listed as actively exploited in the KEV catalog, the potential for exploitation remains a concern. Organizations should schedule remediation and ensure they remain vigilant against potential exploitation.

Affected Versions
The following Django versions are affected by this vulnerability: 6.0 prior to 6.0.2, 5.2 prior to 5.2.11, and 4.2 prior to 4.2.28. All versions prior to vendor patch are vulnerable.
Mitigation & Remediation
Organizations are advised to upgrade to Django versions 6.0.2, 5.2.11, or 4.2.28 to mitigate this vulnerability effectively. If immediate patching is not feasible, consider implementing input validation and sanitization to prevent SQL injection attacks.
Regular security assessments, including penetration testing, are also recommended to identify and remediate vulnerabilities proactively.
Detection Guidance
Monitoring logs for unusual database queries and behavior can help detect potential exploitation attempts. Look for patterns indicating SQL injection attempts, such as unexpected characters or commands being executed.
