WebSocket API vulnerabilities

The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks or brute-force attacks to gain unauthorized access.

A flaw has been found in AV Stumpfl Pixera Two Media Server up to version 25.2 R2 in an unknown function of the Websocket API component, allowing for code injection. The attack can be initiated remotely.

A denial-of-service vulnerability exists in the WebSocket API due to insufficient validation and handling of JSON-based requests. A low-privileged authenticated attacker can send a specially crafted request that causes service disruption and may result in an unexpected device reboot.
