What it is

⚡ A sneaky unquoted service path opens the door for local users to run code with elevated privileges! This one’s happening in the Acer Updater Service. 🔥 Think of it like a restaurant where a waiter can serve any dish without checking the menu — if they slip in something toxic before the chef starts cooking, the whole meal could be ruined! An attacker could easily exploit this to inject malicious executables that run with LocalSystem permissions, potentially taking full control of the system. This could lead to devastating outcomes, including data theft, system corruption, or worse!
