A vulnerability exists within the httpd server of the TP-Link WA850RE Universal Wi-Fi Range Extender that allows authenticated attackers to inject arbitrary commands as arguments to an execve() call due to a lack of input sanitization. Injected commands are executed with root privileges. This issue is further exacerbated when combined with the configuration leak from EIP-9098806c.
