CVE-2021-46304

Estado: ModificadaAlta (7.5)—

A vulnerability has been identified in CP-8000 MASTER MODULE WITH I/O -25/+70°C (All versions), CP-8000 MASTER MODULE WITH I/O -40/+70°C (All versions), CP-8021 MASTER MODULE (All versions), CP-8022 MASTER MODULE WITH GPRS (All versions). The component allows to activate a web server module which provides unauthenticated access to its web pages. This could allow an attacker to retrieve debug-level information from the component such as internal network topology or connected systems.

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).
