MongoDB
Parameter Value
CVSS 7.1 (HIGH)
Type CWE-125 (Out-of-bounds Read)
Vendor MongoDB
Public PoC No

An issue in MongoDB Server's geospatial query processing could allow an authenticated user with write privileges to cause certain malformed geometry data to be stored and later processed without proper validation. Subsequent queries against this data could then result in the server accessing memory outside its intended bounds. This could result in a server crash (denial of service) and may expose a limited amount of server process memory.
