Detailsinfo

A vulnerability, which was classified as problematic, has been found in STIGTSP Net::CIDR::Lite up to 0.23 on Perl. Affected by this issue is the function find/bin_find. The manipulation with an unknown input leads to a improper validation of unsafe equivalence in input vulnerability. Using CWE to declare the problem leads to CWE-1289. The product receives an input value that is used as a resource identifier or other type of reference, but it does not validate or incorrectly validates that the input is equivalent to a potentially-unsafe value. Impacted is integrity. CVE summarizes:

Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass. Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result. Example: my $cidr = Net::CIDR::Lite->new(); $cidr->add("::1\n/128"); $cidr->find("::1a"); # incorrectly returns true See also CVE-2026-45191.
