What it is

⚡ An authentication bypass just made itself at home in Screen SFT DAB 1.9.3! A crafty attacker could reuse session identifiers to play around with your device management API like a kid in a candy store. 🍬 Think of it like a hotel where someone manages to sneak in using a guest's room key — they can access any room without any verification. Just like that guest, attackers can issue unauthorized requests and perform critical operations on your transmitter. This could lead to all sorts of chaos! An attacker could manipulate settings, push unauthorized commands, or even take full control of your device, leaving you with a massive security headache and potential loss of data.
