CWE-338Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Description

Common consequences· 1

• Access Control — Bypass Protection Mechanism
  If a PRNG is used for authentication and authorization, such as a session ID or a seed for generating a cryptographic key, then an attacker may be able to easily guess the ID or cryptographic key and gain access to restricted functionality.

Potential mitigations· 1

• [Implementation]Use functions or hardware which use a hardware-based random number generation for all crypto. This is the recommended solution. Use CyptGenRandom on Windows, or hw_rand() on Linux.
