Title
Net::CIDR::Set versions through 0.20 for Perl did not validate IP addresses
Summary
Net::CIDR::Set versions through 0.20 for Perl did not validate IP addresses.
The add method called the _encode method to parse addresses. If the addresses did not look like netmasks or network ranges, then they were assumed to single IP addresses and passed back to itself as a 32-bit or 128-bit netmask.
If the argument was not a well-formed IP address, then this would lead to indefinite recursion.
An attacker could use this to cause a denial of service.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
