Details

Net::NSCA::Client versions through 0.009002 for Perl uses a poor random number generator.

Version v0.003 switched to use Data::Rand::Obscure instead of Crypt::Random for generation of a random initialisation vectors.

Data::Rand::Obscure uses Perl's built-in rand() function, which is not suitable for cryptographic functions.

Severity ?

9.1 (Critical)
