Description
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the wireless.cgi binary that allow unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the sz11gChannel or PIN POST parameters. Attackers can exploit unsanitized parameter handling in the set_wifi_basic and set_wifi_do_wps functions to achieve remote code execution without authentication.
