Lifecycle Timeline
2DescriptionCVE.org
An application using the MongoDB BI Connector ODBC Driver may encounter a memory-safety issue when a submitted SQL statement contains an unusually long run of digits following a LIMIT clause. The issue occurs only on connections where the driver's optional prefetch setting is enabled, and stems from the driver copying the digit sequence into a fixed-size internal buffer without checking its length. A user able to influence the numeric portion of a LIMIT clause could cause the hosting application process to terminate unexpectedly or corrupt adjacent memory in that process.
AnalysisAI
Stack-based buffer overflow in MongoDB BI Connector ODBC Driver allows an authenticated user who can influence the numeric argument of a SQL LIMIT clause to crash the hosting application process or corrupt adjacent stack memory. The vulnerability is gated by a non-default driver configuration: the prefetch feature must be explicitly enabled, narrowing real-world exposure to that subset of deployments. …

Vulnerability AssessmentAI
| Exploitation | Two specific conditions must simultaneously be present for exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The reporter-assigned CVSS 4.0 score of 6.0 (Medium) with vector AV:N/AC:L/AT:P/PR:L/UI:N reflects a balanced picture: network-reachable and requiring no special complexity once conditions are met, but gated by two real constraints - authenticated access (PR:L) and the non-default prefetch setting (AT:P). … 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 | Consult the MongoDB BI Connector ODBC Driver releases page at https://github.com/mongodb/mongo-bi-connector-odbc-driver/releases to identify and deploy the latest release containing the fix - an exact patched version number is not confirmed in the available advisory data and must be determined from release notes there. … Detailed patch versions, workarounds, and compensating controls in full report. |
