CVE-2026-97230

Estado: AplazadaCrítica (9.8)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Módulo malicioso en cadena de suministro (supply chain) ejecuta código Python obfuscado desde URL remota al instalar/usar el paquete, permitiendo ejecución arbitraria sin dejar scripts en disco.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
