Threat: Panel Amadey.d.c
Vulnerability: Cross Site Scripting (XSS)
Family: Amadey
Type: Web Panel
MD5: 50467c891bf7de34d2d65fa93ab8b558 (Login.php)
SHA256: 65623eead2bcba66817861246e842386d712c38c5c5558e50eb49cffa2a1035d
Vuln ID: MVID-2024-0680
Disclosure: 05/09/2024
Description: The Amadey C2 web panel is written in PHP for remote
administration capability. The Login.php webpage accepts HTTP GET "l" and
"p" parameters which are passed to the backend server side code: $_GET["l"]
 name=\"login\",  $_GET["p"] , name=\"password\". However, there is no
secure coding practice of filtering input or sanitization of output. Panel
users who visit a third-party attacker website or click an infected link,
can trigger arbitrary client side JS code execution in the security context
of the current user. This can result in data theft or GEO location
disclosure of the user accessing the Amadey web interface.

The submit button contains the text "Unlock".
Entering incorrect password results in URI of "?wrong=1" and displays
"Wrong login or password", after a few seconds delay redirects back to
Login.php.

http://127.0.0.1/Panel.Amadey.d.c/Login.php?wrong=1
Wrong login or password

The web panel HTML source code for the URL "Login.php?wrong=1" contains the
letters "CC" plus the Domain/IP within brackets[x.x.x.x] within the HTML
title tag.
