Insecure encryption algorithm

Description

The application uses insecure encryption algorithms.

Impact

• Reverse the ciphertext and collect sensible information.
• Tamper protected data by exploiting algorithm collisions.

Recommendation

Use algorithms considered cryptographically secure.

Threat

Anonymous attacker from adjacent network.

Expected Remediation Time

⌚ minutes.

Score

Default score using CVSS 3.1. It may change depending on the context of the src.
