CVE-2024-57868
Web::API 2.8 and earlier for Perl uses insecure rand() function for cryptographic functions
Description

Web::API 2.8 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Web::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.

Solution
Update Web::API and its dependencies to use a cryptographically secure random number generator.
  • Update Web::API to a version that uses a secure random source.
  • Ensure Data::Random is not used for cryptographic purposes.
  • Replace rand() with a cryptographically secure PRNG.
