CVE-2023-48194

Estado: ModificadaCrítica (9.8)—💥 PoC

Vulnerability in Tenda AC8v4 .V16.03.34.09 due to sscanf and the last digit of s8 being overwritten with \x0. After executing set_client_qos, control over the gp register can be obtained.

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.
