HIGH 7.5

DescriptionCVE.org

The embedded web interface of the device does not support HTTPS/TLS for authentication and uses HTTP Basic Authentication. Traffic is encoded but not encrypted, exposing user credentials to passive interception by attackers on the same network.

AnalysisAI

HTTP Basic Authentication over unencrypted connections in the device's embedded web interface allows attackers on the same network to passively intercept and capture user credentials. This cleartext transmission of authentication data exposes administrative access to network-based eavesdropping attacks. The lack of HTTPS/TLS support creates a significant credential compromise risk for affected devices with no available patch.

Technical ContextAI

Classified as CWE-319 (Cleartext Transmission of Sensitive Information). The embedded web interface of the device does not support HTTPS/TLS for authentication and uses HTTP Basic Authentication. Traffic is encoded but not encrypted, exposing user credentials to passive interception by attackers on the same network.
