MongoDB sqlCollectionsFields Bypass checkSQL Validation Leading to SQL Injection (GHSA-wwnh-288h-jjny)

Vulnerability Summary: Bypasses Validation (GHSA-wwnh-288h-jjny) Vulnerability Overview This vulnerability exists in the function within MongoDB, which is responsible for converting SQL collection fields (such as , , , etc.) into MongoDB's internal representation. Due to insufficient validation of input fields, attackers can craft malicious requests to bypass the security check, thereby injecting arbitrary SQL statements or executing unintended operations. Scope of Impact Affected Versions: MongoDB 4.0.x to 5.0.x (see official advisory for specific versions) Affected Components: function and related SQL collection processing logic Attack Surface: SQL collection field parameters passed via API interfaces (e.g., , , ) Risk Level: High (can lead to SQL injection, data leakage, privilege escalation, etc.) Remediation Official Fix: The issue has been addressed in subsequent versions; upgrading to the latest stable release is recommended. Temporary Mitigations: - Implement strict whitelist validation for all field values passed to . - Disable or restrict access to SQL collection-related interfaces for untrusted clients. - Add additional validation logic at the application layer to ensure field values conform to expected formats. POC / Exploitation Code > ⚠️ Note: The code above is for demonstration of the vulnerability principle only. Actual exploitation requires specific environmental conditions. Do not test or deploy such code in production environments. --- CVE Identifier: GHSA-wwnh-288h-jjny Report Date: 2023-08-07 Fix Status: Fixed (see official release notes)
