CVE-2021-34579

Estado: ModificadaAlta (7.5)—

In Phoenix Contact: FL MGUARD DM version 1.12.0 and 1.13.0 access to the Apache web server being installed as part of the FL MGUARD DM on Microsoft Windows does not require login credentials even if configured during installation.Attackers with network access to the Apache web server can download and therefore read mGuard configuration profiles (“ATV profiles”). Such configuration profiles may contain sensitive information, e.g. private keys associated with IPsec VPN connections.

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).
