Critical CVSS 9.2

The Use of a Hard-coded Cryptographic Key vulnerability in Juniper Networks Juniper Cloud Native Router (JCNR) and containerized routing Protocol Deamon (cRPD) products allows an attacker to perform Person-in-the-Middle (PitM) attacks which results in complete compromise of the container. Due to hardcoded SSH host keys being present on the container, a PitM attacker can intercept SSH traffic without being detected. This issue affects Juniper Networks JCNR: * All versions before 23.4. This issue affects Juniper Networks cRPD: * All versions before 23.4R1.

Matched remediation archetype

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.
