Lifecycle Timeline
3DescriptionCVE.org
In MongoDB Connector for BI, MongoDB object names such as collection, field, and index names are placed into the quoted identifiers of the DDL text returned by SHOW CREATE statements without escaping the identifier delimiter. A user with permission to write to a sampled MongoDB collection can choose a name that closes the quoted identifier early, so that additional SQL text becomes part of the generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.
AnalysisAI
SQL injection via identifier escaping failure in MongoDB Connector for BI allows a low-privileged MongoDB user to craft collection, field, or index names that break out of SQL quoted identifiers, embedding arbitrary SQL into the DDL output produced by SHOW CREATE statements. Any user with write access to a sampled MongoDB collection can plant the payload; the injected SQL executes only when an operator or automated pipeline later replays that generated DDL against a downstream SQL-compatible server, triggering execution with that session's privileges. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold write permission to at least one MongoDB collection that is sampled and exposed by the BI Connector - this is the explicit PR:L (low privilege) prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:A) scores 8.5, reflecting low-complexity network exploitation requiring only low privileges but mandating an active interaction step - the DDL replay - before the payload fires. … 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 | The primary remediation is to upgrade MongoDB BI Connector to the fixed version documented in the vendor release notes at https://www.mongodb.com/docs/bi-connector/current/release-notes/; the exact patched version number is not confirmed from available intelligence and must be verified directly against that advisory before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all MongoDB instances using the BI Connector and restrict write access to sampled collections to trusted administrators; implement network segmentation isolating downstream SQL servers from untrusted MongoDB sources. …
