## Technical details

The vulnerability is a command injection flaw in the crash dump handler of the Sony XAV-9500ES. It stems from insufficient validation of user-supplied input before passing it to a system call. An attacker who has already obtained the ability to execute low-privileged code can craft a malicious input that breaks out of the intended command context and injects arbitrary shell commands. When the crash dump handler processes this input, the injected commands execute with root privileges, allowing full privilege escalation and arbitrary code execution. A patch has been released by Sony.
