Summary

A CWE-288 authentication bypass vulnerability in the Positron Broadcast Signal Processor TRA7005 v1.20 allows attackers to bypass authentication and access unauthorized protected areas of the application. The vulnerability has a CVSS score of 7.5 (high severity) with a network attack vector, low attack complexity, and no privileges or user interaction required. Positron has not engaged with CISA to develop a fix, and no patch is available for affected versions.

What this means
What could happen
An attacker who can reach the TRA7005 over the network could bypass authentication and access functions they should not have permission to use, potentially modifying broadcast signal processing parameters or configurations.
Who's at risk
Broadcast and media facility operators using Positron TRA7005 Broadcast Signal Processors should be concerned. This device is typically deployed in broadcast centers, transmission facilities, and content distribution networks where signal integrity and configuration control are critical.
How it could be exploited
An attacker on the network sends requests to the TRA7005 without valid credentials. The authentication bypass vulnerability allows the requests to succeed, giving the attacker unauthorized access to protected features of the application.
Prerequisites
  • Network access to the Broadcast Signal Processor TRA7005
  • Device must be reachable from attacker's network location
  • No valid credentials required
