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 con AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-787 (out-of-bounds write) sugiere ejecución de código (T1059), aunque la descripción oficial solo menciona 'unexpected system termination', lo que apunta más a denegación de servicio (T1499.004 - application cras

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