Small Space of Random Values
The number of possible random values is smaller than needed by the product, making it more susceptible to brute force attacks.
Use products or modules that conform to FIPS 140-2 [REF-267] to avoid obvious entropy problems. Consult FIPS 140-2 Annex C ("Approved Random Number Generators").
An attacker could easily guess the values used. This could lead to unauthorized access to a system if the seed is used for authentication and authorization.
