Product: Gazelle
Download: https://github.com/WhatCD/Gazelle
Vunlerable Version: latest version
Tested Version: latest version
Author: ADLab of Venustech

Advisory Details:
A Cross-Site Scripting (XSS) was discovered in “Gazelle latest version”, which can be exploited to execute arbitrary code.
The vulnerability exists due to insufficient filtration of user-supplied data in the “action” HTTP GET parameter passed to the “Gazelle-master/sections/tools/finances/bitcoin_balance.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:
http://localhost/.../Gazelle-master/sections/tools/finances/bitcoin_balance.php?action=%22%3E%3Cscript%3Ealert(1);%3C/script%3E%3C%22
