What it is

🔥 A crafty title change is all it takes! ConEmu through version 220807 and Cmder before 1.3.21 let attackers manipulate terminal titles to execute arbitrary commands. ⚡ Imagine a restaurant where the waiter can change the name on your order to something completely different, allowing them to serve whatever they want in your name. In this case, control characters are the sneaky ingredient that lets malicious commands slip right into the kitchen! An attacker could exploit this vulnerability to execute any command as soon as the terminal title is changed, potentially gaining full control over the system. This is absolutely devastating, as it opens the door to unauthorized access and manipulation of sensitive data!
