CVE-2020-9015

Estado: ModificadaCrítica (9.8)—💥 Exploit

Arista DCS-7050QX-32S-R 4.20.9M, DCS-7050CX3-32S-R 4.20.11M, and DCS-7280SRAM-48C6-R 4.22.0.1F devices (and possibly other products) allow attackers to bypass intended TACACS+ shell restrictions via a | character. NOTE: the vendor reports that this is a configuration issue relating to an overly permissive regular expression in the TACACS+ server permitted commands

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
