Vulnerability from osv_openeuler – Published: 2023-07-08 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

perl-CPAN security update

Details

The CPAN module automates or at least simplifies the make and install of perl modules and extensions. It includes some primitive searching capabilities and knows how to use LWP, HTTP::Tiny, Net::FTP and certain external download clients to fetch distributions from the net. The CPAN module also supports named and versioned bundles of modules. Bundles simplify handling of sets of related modules.

Security Fix(es):

CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS.(CVE-2023-31484)

Severity

8.1 (High)

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.
