CVE-2019-3777 — Pivotal Software Application Service security vulnerability

Critical CVSS 9.8

Pivotal Application Service (PAS), versions 2.2.x prior to 2.2.12, 2.3.x prior to 2.3.7 and 2.4.x prior to 2.4.3, contain apps manager that uses a cloud controller proxy that fails to verify SSL certs. A remote unauthenticated attacker that could hijack the Cloud Controller's DNS record could intercept access tokens sent to the Cloud Controller, giving the attacker access to the user's resources in the Cloud Controller

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.
