path /password.html↗

• → HTTP GET request to /password.html returns HTTP 200 and response body contains the strings 'Password Setting', "addCfg('username'", and "addCfg('newpass'" — all three must be present to confirm plaintext credential exposure.
• → The vulnerable page is served over plain HTTP (not HTTPS), making credentials interceptable in transit as well as readable in the page source. ↗

• · The vulnerability is specific to Acexy Wireless-N WiFi Repeater REV 1.0 firmware version 28.08.06.1. Scanning other firmware versions or hardware revisions may produce false positives or false negatives.
• · Detection requires all three keyword matches ('Password Setting', "addCfg('username'", "addCfg('newpass'") AND an HTTP 200 status; matching on fewer conditions risks false positives against other embedded web UIs.
