CVE intelligence and bounded remediation
CVE-2019-5723 — An issue was discovered in portier vision 4.4.4.2 and 4.4.4.6
Critical
CVSS 9.8
An issue was discovered in portier vision 4.4.4.2 and 4.4.4.6. Passwords are stored using reversible encryption rather than as a hash value, and the used Vigenere algorithm is badly outdated. Moreover, the encryption key is static and too short. Due to this, the passwords stored by the application can be easily decrypted.

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.
