What it is

🚨 An improper input validation flaw in ZOOK software could let attackers create files without permission — like a guest at a hotel getting a room key to access any suite! 🔥 Think of ZOOK’s Tight File CMD function as a hotel check-in desk that accidentally gives anyone a master key instead of just their assigned room key. Just like that, an attacker can create and execute any file they wish, bypassing necessary checks. This vulnerability could allow remote attackers to run arbitrary files within the ZOOK agent program, opening the door to potentially devastating actions — stealing data, installing malware, or even disrupting services. The risks are immense, given that unauthorized access could mean full control over sensitive systems!
