url /reboot.cgi↗

command curl -d "reboot_op=reboot" -X POST http://192.168.1.10/reboot.cgi↗

• → Alert on any HTTP POST to the path /reboot.cgi on TP-Link TL-SG105E web management interfaces (typically on LAN/management network), especially from unauthenticated sources. ↗

• · The exploit targets TP-Link TP-SG105E V4 firmware version 1.0.0 Build 20181120 specifically; patched firmware (1.0.0 Build 20200119 rel.52079) restricts access to the internal API and is not vulnerable. ↗
• · The vulnerable endpoint is part of the device's web management interface; if the management interface is exposed beyond the local network, the attack surface is significantly increased. ↗
