MongoDB Server: Improper Certificate Validation
CVE-2024-1351 is a critical-severity improper certificate validation vulnerability in MongoDB Server from MongoDB, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected MongoDB Server versions: 7.0 through 7.0.5; 6.0 through 6.0.13; 5.0 through 5.0.24, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.5% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of MongoDB Server you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on jira.mongodb.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Under certain configurations of --tlsCAFile and tls.CAFile, MongoDB Server may skip peer certificate validation which may result in untrusted connections to succeed. This may effectively reduce the security guarantees provided by TLS and open connections that should have been closed due to failing certificate validation. This issue affects MongoDB Server v7.0 versions prior to and including 7.0.5, MongoDB Server v6.0 versions prior to and including 6.0.13, MongoDB Server v5.0 versions prior to and including 5.0.24 and MongoDB Server v4.4 versions prior to and including 4.4.28. Required Configuration : A server process will allow incoming connections to skip peer certificate validation if the server process was started with TLS enabled (net.tls.mode set to allowTLS, preferTLS, or requireTLS) and without a net.tls.CAFile configured.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
