CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). El texto describe ejecución arbitraria de código mediante descarga sin validación de certificado (CWE-295), permitiendo MITM (T1557) e inyección de código malicioso.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
