Descriptions

An unauthenticated remote attacker can extract a session token with a MitM attack and gain web-based
management access with the privileges of the currently logged in user due to cleartext transmission of sensitive information. No additional user interaction is required. The access is limited as only non-sensitive information can be obtained but the availability can be seriously affected.

Un atacante remoto no autenticado puede extraer un token de sesión con un ataque MitM y obtener acceso de administración basado en web con los privilegios del usuario actualmente conectado debido a la transmisión de texto plano de información confidencial. No se requiere interacción adicional del usuario. El acceso es limitado ya que sólo se puede obtener información no confidencial pero la disponibilidad puede verse seriamente afectada.

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Phoenix Contact CHARX SEC-3100 devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the configuration of nginx. The issue results from a lack of encryption. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the user-app account.
