Technical details

The vulnerability is a deliberate inclusion of malicious code in the module's certificate generation function. A Python dropper script embedded in lib/Crypt/SelfCertificate/sample/cert.pem fetches additional code from a base64-obfuscated URL and executes it directly, requiring no user interaction beyond module installation. The attack succeeds locally on the affected system with the permissions of the user running the installation.
