CVE-2020-7924: Specific command line parameter might result in accepting invalid certificate

Usage of specific command line parameter in MongoDB Tools which was originally intended to just skip hostname checks, may result in MongoDB skipping all certificate validation. This may result in accepting invalid certificates.This issue affects: MongoDB Inc. MongoDB Database Tools 3.6 versions later than 3.6.5; 3.6 versions prior to 3.6.21; 4.0 versions prior to 4.0.21; 4.2 versions prior to 4.2.11; 100 versions prior to 100.2.0. MongoDB Inc. Mongomirror 0 versions later than 0.6.0.

Security readout for executives and security teams

Plain-English summary

Some MongoDB command-line tools could treat a certificate-checking option too broadly. A setting meant to skip only hostname checks could make the tool accept invalid certificates, weakening trust in encrypted connections and exposing data in transit to interception or tampering in specific operational workflows.

Executive priority

Treat this as a targeted operational risk, not an internet-wide emergency. Prioritize environments where MongoDB tooling moves sensitive data over TLS, especially automated migration or backup paths. Fix through tool upgrades and configuration review.

Technical view

CVE-2020-7924 is a CWE-295 certificate validation flaw in MongoDB Database Tools and Mongomirror. A specific command-line parameter could cause certificate validation to be skipped beyond hostname verification. CVSS 3.1 is 4.2: network attack vector, high complexity, user interaction required, low confidentiality and integrity impact, no availability impact.

Likely exposure

Exposure is most likely where affected MongoDB Database Tools or Mongomirror versions are used with TLS and the relevant certificate-related command-line option in scripts, migration jobs, backups, imports, exports, or mirror workflows.

Exploitation context

The supplied sources do not show active exploitation, and the CVE is not listed as KEV. Exploitation would depend on an affected tool invocation and conditions where accepting an invalid certificate matters, such as a hostile or compromised network path.

Researcher notes

The public bundle identifies affected version ranges and root cause but does not name the exact parameter or provide full vendor remediation detail for Mongomirror. Avoid assuming exploitability without confirming tool version, TLS use, and invocation flags in the target environment.

Mitigation direction

  • Upgrade MongoDB Database Tools to fixed versions: 3.6.21, 4.0.21, 4.2.11, or 100.2.0 or later.
  • Review MongoDB guidance for Mongomirror because the source does not name a fixed Mongomirror version.
  • Remove or avoid the certificate-related parameter unless vendor guidance explicitly permits its use.
  • Ensure TLS workflows require valid certificates from trusted authorities.
  • Update automation, runbooks, and images that package affected MongoDB tools.

Validation and detection

  • Inventory installed MongoDB Database Tools and Mongomirror versions across hosts, containers, and CI images.
  • Review backup, migration, import, export, and mirror scripts for certificate-validation-related options.
  • Confirm production TLS connections reject invalid or untrusted certificates under normal operations.
  • Check vendor advisories or Jira TOOLS-2587 for product-specific remediation details.
  • Document any remaining legacy tool usage and compensating controls.

Improper Certificate Validation

Improper Certificate Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
