Title: Sielco Radio Link 2.06 ‘id’ Cookie Brute Force Session Hijacking
Advisory ID: ZSL-2023-5762
Type: Local/Remote
Impact: Security Bypass
Risk: (4/5)
Release Date: 30.03.2023
Sielco develops and produces radio links for all transmission and reception needs, thanks to innovative units and excellent performances, accompanied by a high reliability and low consumption.
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.
