CVE intelligence and bounded remediation

CVE-2017-15326 — DBS3900 TDD LTE V100R003C00, V100R004C10 have a weak encryption algorithm security vulnerability

Medium CVSS 4.3

DBS3900 TDD LTE V100R003C00, V100R004C10 have a weak encryption algorithm security vulnerability. DBS3900 TDD LTE supports SSL/TLS protocol negotiation using insecure encryption algorithms. If an insecure encryption algorithm is negotiated in the communication, an unauthenticated remote attacker can exploit this vulnerability to crack the encrypted data and cause information leakage.

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.
