CVE-2025-1828 | Perl - Crypt::Random Operational Intel

Executive Risk Summary

"The Crypt::Random Perl package versions 1.05 through 1.55 may use the insecure rand() function for cryptographic functions, posing a significant risk to the security of applications relying on this package. This vulnerability is particularly concerning for Windows versions of Perl, which will encounter this issue by default due to the lack of /dev/urandom or an Entropy Gathering Daemon (egd) service."

Internal Work Notes

Recommend upgrading to a version of Crypt::Random that uses a cryptographically strong random number generator, such as one that utilizes /dev/urandom or an Entropy Gathering Daemon (egd) service, to mitigate this vulnerability.

Original NVD Description

"Crypt::Random Perl package 1.05 through 1.55 may use rand() function, which is not cryptographically strong, for cryptographic functions. If the Provider is not specified and /dev/urandom or an Entropy Gathering Daemon (egd) service is not available Crypt::Random will default to use the insecure Crypt::Random::rand provider. In particular, Windows versions of perl will encounter this issue by default."
