What it is

⚠️ Tenda routers G1 and G3 have a sneaky command injection vulnerability that allows attacks through the pic_name parameter—think of it as a recipe that lets an intruder add their own secret ingredient! 🔥 Imagine a restaurant where customers can submit their own dishes without any approval—one rogue chef could turn a tasty meal into a mystery dish! That's exactly how this command injection works, letting attackers execute arbitrary commands without anyone checking their credentials. An attacker could leverage this vulnerability to run any command on the router, potentially taking control of your entire network! This could lead to unauthorized access, data leaks, or even turning your router into a malicious node in a larger attack. Absolutely devastating for those relying on these devices!
