Description

IO::Socket::SSL::SelfCertificate versions 1.00 for Perl contains malware which executes Python code from an obfuscated URL.

The generate_certificate runs a Python script saved as a certificate file. The pyhton script attempts to retrieve code from a hardcoded http URL that is obfuscated with base64 encoding and run the response body directly.

The impact is that arbitrary code can be invoked as the user, without a dropped script being saved on the affected host.

The releases have no test scripts nor build hooks. The intention may have been to trigger the payload after installation.

The dropper script is in lib/Crypt/SelfCertificate/sample/cert.pem.

This is similar to CVE-2026-95831 for the module Crypt::SelfCertificate.
