Delphi : Weak seed of random number generator

The RandSeed variable is assigned an integer value. The corresponding pseudo-random number generator generates a predictable sequence.

The work of many cryptographic algorithms based on cryptographically stable pseudo-random number generator. Some algorithms take the seed as an additional parameter and for each value of this parameter generate a predictable sequence. In this case, the security of the system is based on the assumption that the seed values will be unpredictable.

Sensitive Data Exposure vulnerabilities take the third place in the “OWASP Top 10 2017” web-application vulnerabilities ranking.
