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.

El vector AV:N/PR:L/UI:N exige privilegios de escritura (PR:L) y, según el texto, el proceso del servidor deja de funcionar al insertar un documento, lo que encaja con DoS por explotación de la aplicación.

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