Description

A flaw was found in Net::CIDR::Lite, a Perl module for handling IP address ranges. This vulnerability allows a remote attacker to bypass IP Access Control Lists (ACLs) due to improper validation of IP address and CIDR (Classless Inter-Domain Routing) mask inputs. Specifically, inputs containing trailing newlines or non-ASCII digit characters are incorrectly processed, leading to a mismatch between the intended and actual IP addresses. This can cause functions like `find()` and `bin_find()` to incorrectly allow or deny access, compromising network security policies.
