CVE-2021-3494 — Theforeman Foreman security vulnerability

Medium CVSS 5.9

A smart proxy that provides a restful API to various sub-systems of the Foreman is affected by the flaw which can cause a Man-in-the-Middle attack. The FreeIPA module of Foreman smart proxy does not check the SSL certificate, thus, an unauthenticated attacker can perform actions in FreeIPA if certain conditions are met. The highest threat from this flaw is to system confidentiality. This flaw affects Foreman versions before 2.5.0.

Cryptography, certificate, signature, and channel validation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
