HighCVSS 7.8Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
A data source definition with an over-length file path may cause the MongoDB BI Connector ODBC Driver setup dialog to write outside an allocated buffer. The issue stems from incorrect buffer capacity calculation in file/folder selection handling and is triggered only when the user opens the setup dialog and initiates a selection. Depending on build configuration, it may lead to abnormal termination or, under certain conditions, execution of unintended code.
Risk Assessment
The risk includes application crashes or potential code execution in the context of the user running the dialog, which could lead to unauthorized actions on the system.
Recommendation
It is recommended to update the MongoDB BI Connector ODBC Driver to a patched version and avoid opening the setup dialog for untrusted data sources.
Original NVD description (English source)
A data source definition containing an over-length file path setting may cause the MongoDB BI Connector ODBC Driver setup dialog to write outside the bounds of an allocated buffer. The issue stems from an incorrect buffer capacity calculation in the dialog's file and folder selection handling, and is reached only when a user opens the setup dialog for such a data source and initiates a file or folder selection. Depending on build configuration, the result may range from abnormal process termination to, under certain conditions, execution of unintended code in the context of the user running the dialog.
