Executive Summary

This vulnerability exists because the embedded web interface of the device does not support HTTPS or TLS for authentication and instead uses HTTP Basic Authentication.

Although the traffic is encoded, it is not encrypted, which means that user credentials can be exposed to passive interception by attackers who are on the same network.

Impact Analysis

Because the authentication traffic is not encrypted, attackers on the same network can intercept user credentials.

This can lead to unauthorized access to the device's web interface, potentially compromising the device's security.

The CVSS base score of 7.5 indicates a high severity impact on confidentiality, meaning sensitive information can be exposed.

Detection Guidance

This vulnerability can be detected by monitoring network traffic for unencrypted HTTP Basic Authentication exchanges to the device's embedded web interface. Since the interface does not support HTTPS/TLS, credentials are transmitted in clear text (encoded but not encrypted), making them visible to passive interception.

To detect this on your network, you can use network packet capture tools such as tcpdump or Wireshark to inspect HTTP traffic for Basic Authentication headers.

• Use tcpdump to capture HTTP traffic on the relevant network interface: tcpdump -i <interface> -A 'tcp port 80'
• In Wireshark, filter traffic with the display filter: http.authbasic
• Look for HTTP requests containing the 'Authorization: Basic' header, which indicates Basic Authentication credentials sent in clear text.

Mitigation Strategies

Immediate mitigation steps include restricting network access to the device's web interface to trusted and secure networks only, such as isolating the device on a separate VLAN or using firewall rules to limit access.

Additionally, avoid using the device's web interface over untrusted or public networks since the credentials are exposed in unencrypted HTTP traffic.

If possible, use network-level encryption such as VPN tunnels to protect traffic to the device until the vendor provides support for HTTPS/TLS.
