CVE-2021-40222

Estado: ModificadaAlta (7.2)—💥 PoC

Rittal CMC PU III Web management Version affected: V3.11.00_2. Version fixed: V3.17.10 is affected by a remote code execution vulnerablity. It is possible to introduce shell code to create a reverse shell in the PU-Hostname field of the TCP/IP Configuration dialog. Web application fails to sanitize user input on Network TCP/IP configuration page. This allows the attacker to inject commands as root on the device which will be executed once the data is received.

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.
