20th percentile - higher than 20% of all known CVEs

Summary

A user able to submit SQL through an application using the MongoDB Connector for BI ODBC driver can supply a positioned-cursor statement whose cursor name exceeds the size of an internal fixed-length buffer. Because the name length is not bounded before the driver builds its diagnostic message, memory adjacent to that buffer is overwritten with user-supplied content. This can terminate the hosting application process and may allow unintended code to run within it.

Risk Assessment

An attacker could crash the process or potentially execute arbitrary code in the context of the application, posing a serious threat to confidentiality and integrity.

Recommendation

Upgrade the MongoDB Connector for BI ODBC driver to a patched version. Restrict access to the application and enforce limits on cursor name lengths in SQL queries.
