⚠️ An unrestricted file upload vulnerability hides in plain sight in ReadyDesk 9.1! Attackers can upload a sneaky .aspx file and execute arbitrary code at will. 🦸♂️ Think of it like a restaurant allowing anyone to bring in their own recipe and use the kitchen — if the chef doesn’t check the ingredient list, someone could sneak in a dish that ruins the entire meal. This vulnerability could allow an attacker to run malicious code on the server, leading to data breaches or even total server takeover. The potential damage could be extensive and absolutely devastating if exploited.
Think of it like a restaurant allowing anyone to bring in their own recipe and use the kitchen — if the chef doesn’t check the ingredient list, someone could sneak in a dish that ruins the entire meal. The flaw resides in the chat/sendfile.aspx endpoint, where attackers can upload .aspx files without proper checks, enabling them to execute arbitrary code remotely.
This vulnerability could allow an attacker to run malicious code on the server, leading to data breaches or even total server takeover.
