VectorAV:N/AC:L/Au:S/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions MongoDB Server versions prior to 5.0.33 MongoDB Server versions prior to 6.0.28 MongoDB Server versions prior to 7.0.34 MongoDB Server versions prior to 8.0.23 MongoDB Server versions prior to 8.2.9 MongoDB Server versions prior to 8.3.2
Description An inconsistency in the internal field-name-to-index mapping within the time-series bucket catalog allows an authenticated user with database write privileges to trigger an out-of-bounds memory write in the mongod process. This memory corruption can lead to arbitrary code execution on the database server, which is particularly critical in multi-tenant clusters.
Recommendations Update versions prior to 5.0.33 to 5.0.33. Update versions prior to 6.0.28 to 6.0.28. Update versions prior to 7.0.34 to 7.0.34. Update versions prior to 8.0.23 to 8.0.23. Update versions prior to 8.2.9 to 8.2.9. Update versions prior to 8.3.2 to 8.3.2.
