https://notcve.org/view.php?id=CVE-2022-3480
A remote, unauthenticated attacker could cause a denial-of-service of PHOENIX CONTACT FL MGUARD and TC MGUARD devices below version 8.9.0 by sending a larger number of unauthenticated HTTPS connections originating from different source IP’s. Configuring firewall limits for incoming connections cannot prevent the issue. Un atacante remoto no autenticado podría provocar una Denegación de Servicio (DoS) de los dispositivos PHOENIX CONTACT FL MGUARD y TC MGUARD inferiores a la versión 8.9.0 al enviar una mayor cantidad de conexiones HTTPS no autenticadas que se originan desde diferentes IP de origen. Configurar los límites de firewall para conexiones entrantes no puede evitar el problema. • https://cert.vde.com/en/advisories/VDE-2022-051 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 9.1EPSS: 0%CPEs: 18EXPL: 0CVE-2020-12523 – Phoenix Contact mGuard Devices versions before 8.8.3: LAN ports get functional after reboot even if they are disabled in the device configuration
https://notcve.org/view.php?id=CVE-2020-12523
On Phoenix Contact mGuard Devices versions before 8.8.3 LAN ports get functional after reboot even if they are disabled in the device configuration. For mGuard devices with integrated switch on the LAN side, single switch ports can be disabled by device configuration. After a reboot these ports get functional independent from their configuration setting: Missing Initialization of Resource En Phoenix Contact mGuard Devices versiones anteriores a 8.8.3, los puertos LAN funcionan después del reinicio, inclusive si están desactivados en la configuración del dispositivo. Para los dispositivos mGuard con switch integrado en el lado de la LAN, los puertos switch únicos pueden ser desactivados mediante la configuración del dispositivo. Después de un reinicio, estos puertos se vuelven funcionales independientemente de su configuración: Falta la Inicialización del Recurso • https://cert.vde.com/en-us/advisories/vde-2020-046 • CWE-909: Missing Initialization of Resource •

https://notcve.org/view.php?id=CVE-2018-5441
An Improper Validation of Integrity Check Value issue was discovered in PHOENIX CONTACT mGuard firmware versions 7.2 to 8.6.0. mGuard devices rely on internal checksums for verification of the internal integrity of the update packages. Verification may not always be performed correctly, allowing an attacker to modify firmware update packages. Se ha descubierto un problema de validación indebida de valores de comprobación de integridad en PHOENIX CONTACT mGuard, en versiones de firmware 7.2 a 8.6.0. Los dispositivos mGuard dependen de sumas de verificación internas para verificar la integridad interna de los paquetes de actualización. La verificación podría no realizarse siempre correctamente, lo que permite que un atacante modifique paquetes de actualización de firmware. • http://www.securityfocus.com/bid/102907 https://cert.vde.com/en-us/advisories/vde-2018-001 https://ics-cert.us-cert.gov/advisories/ICSA-18-030-01 • CWE-20: Improper Input Validation CWE-354: Improper Validation of Integrity Check Value •
