CVE-2024-21754

Estado: ModificadaMedia (4.4)—💥 PoC

A use of password hash with insufficient computational effort vulnerability [CWE-916] affecting FortiOS version 7.4.3 and below, 7.2 all versions, 7.0 all versions, 6.4 all versions and FortiProxy version 7.4.2 and below, 7.2 all versions, 7.0 all versions, 2.0 all versions may allow a privileged attacker with super-admin profile and CLI access to decrypting the backup file.

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
