Advisory Details:
A Cross-Site Scripting (XSS) was discovered in “ESP8266 WiFi File Manager latest version”, which can be exploited to execute arbitrary code.
The vulnerability exists due to insufficient filtration of user-supplied data in the “chipIP” HTTP POST parameter passed to the “ESP8266_WiFi_File_Manager-master/PHP_files/send_Restart.php” URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
The exploitation example below uses the "alert()" JavaScript function to see a pop-up messagebox:
Poc:
(1)
Post:chipIP= ><script>alert(1);</script><
To
http://localhost/.../ESP8266_WiFi_File_Manager-master/PHP_files/send_Restart.php
