Title: Sielco Analog FM Transmitter 2.12 ‘id’ Cookie Brute Force Session Hijacking
Advisory ID: ZSL-2023-5758
Type: Local/Remote
Impact: Security Bypass
Risk: (4/5)
Release Date: 28.03.2023
Summary
Sielco designs and produces FM radio transmitters for professional broadcasting. The in-house laboratory develops standard and customised solutions to meet all needs. Whether digital or analogue, each product is studied to ensure reliability, resistance over time and a high standard of safety. Sielco transmitters are distributed throughout the world and serve many radios in Europe, South America, Africa, Oceania and China.
Description
The Cookie session ID ‘id’ is of an insufficient length and can be exploited by brute force, which may allow a remote attacker to obtain a valid session, bypass authentication and manipulate the transmitter.
