The specific flaw exists within the web-based user interface. The issue results from the lack of proper management of sensitive information. An attacker can leverage this vulnerability to disclose information in the context of the device. Was ZDI-CAN-28297.

Executive ViewAI

Why It Matters

ALGO 8180 IP Audio Alerter devices are vulnerable to information disclosure attacks that could expose authentication credentials through the web interface. An attacker with network access can harvest session cookies without authentication, potentially leading to unauthorized device control and lateral network movement. This affects any organization using these devices for emergency communications.

Business Impact: High

Compensating Controls

Restrict network access to the ALGO 8180 web UI via firewall rules to trusted administrative networks only; implement network segmentation to isolate devices; deploy a WAF with rules to detect and block responses containing session cookies in the body; disable remote web UI access if not operationally required; enforce VPN-only administrative access; implement continuous monitoring and logging of authentication attempts to these devices.
