CVE-2025-3218 — Ibm I security vulnerability

Medium CVSS 5.4

IBM i 7.2, 7.3, 7.4, 7.5, and 7.6 is vulnerable to authentication and authorization attacks due to incorrect validation processing in IBM i Netserver. A malicious actor could use the weaknesses, in conjunction with brute force authentication attacks or to bypass authority restrictions, to access the server.

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.
