CVE-2026-2507

Estado: AplazadaAlta (8.7)—

When BIG-IP AFM or BIG-IP DDoS is provisioned, undisclosed traffic can cause TMM to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

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.

Vector CVSS:4.0 con AV:N/PR:N/UI:N indica acceso de red sin privilegios ni interacción; VA:H apunta a disponibilidad. F5 BIG-IP expuesto permite enviar tráfico malformado causando DoS (TMM termina).

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.
