Lifecycle Timeline

Improper handling of case sensitivity in the configuration validation component of MongoDB Server may cause the authorization subsystem to remain in a default disabled state during server startup. An unauthenticated user with network access to a deployment where this condition occurs can perform arbitrary administrative operations, resulting in full impact of data confidentiality, integrity, and availability.

AnalysisAI
Authorization bypass in MongoDB Server (7.0.x before 7.0.41, 8.0.x before 8.0.30, 8.3.x before 8.3.9) allows unauthenticated network attackers to perform arbitrary administrative operations. An improper case-sensitivity flaw (CWE-178) in the configuration validation component can cause the authorization subsystem to silently remain in its default disabled state during server startup, leaving the deployment wide open with no access controls enforced. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the affected deployment to have actually entered the vulnerable state - specifically, the configuration validation component must have mis-evaluated the authorization setting due to a case-sensitivity mismatch, causing the authorization subsystem to remain in its default disabled state at server startup (this is the AT:P attack requirement in the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 vector (CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H, base 9.2) is internally consistent with the description: network reachable, no privileges, no user interaction, and full impact once triggered - but the AT:P (Attack Requirements: Present) metric correctly captures that exploitation is conditional on the specific misconfiguration/casing state actually occurring at startup rather than being universal. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to a fixed release for your branch: MongoDB Server 7.0.41, 8.0.30, or 8.3.9 respectively (Patch available from vendor; see the vendor ticket https://jira.mongodb.org/browse/SERVER-131229 for the authoritative advisory). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all MongoDB Server instances and identify those running 7.0.x, 8.0.x, or 8.3.x versions; immediately verify that authorization is properly enabled in each instance configuration and review database access logs for suspicious administrative operations. …
