Summary
WebService::Xero 0.11 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Specifically WebService::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.

Summary
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.

Summary
Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
This issue affects operating systems where "/dev/urandom'" is unavailable. In that case, Crypt::CBC will fallback to use the insecure rand() function.

Mitigation
Phase: Implementation
Description:
- Use functions or hardware which use a hardware-based random number generation for all crypto. This is the recommended solution. Use CyptGenRandom on Windows, or hw_rand() on Linux.
