CWE-337—Predictable Seed in Pseudo-Random Number Generator (PRNG)

名称

Predictable Seed in Pseudo-Random Number Generator (PRNG)

描述

A Pseudo-Random Number Generator (PRNG) is initialized from a predictable seed, such as the process ID or system time.

The use of predictable seeds significantly reduces the number of possible seeds that an attacker would need to test in order to predict which random numbers will be generated by the PRNG.
