Discovery / credits: Malvuln - malvuln.com (c) 2022 Original source: https://malvuln.com/advisory/8abb41f6e7010d70c90f65fd9a740faa_B.txt Contact: malvuln13@gmail.com Media: twitter.com/malvuln Threat: Win32.MarsStealer Web Panel Vulnerability: Unauthenticated Remote Persistent XSS Description: The Mars-Stealer web interface has a "Marker Rules" component area. Third-party attackers who can reach the Mars-Stealer server can send HTTP POST requests injecting arbitrary JS code into the "mars" MySql database in the markerrule table. This results in a persistent cross site scripting condition, executing client side code in the security context of the currently logged on user anytime the WebUI is accessed. This can result in PHPSESSID token and data theft or GEO location disclosure of the user accessing the Mars-Stealer WebUI. PHP code snippet "markeractions.php" require_once '../../db.php'; switch (trim($_POST['func'])) { case "markeradd": markeradd(); break; case "markerdelete": markerdelete(); break; case "markeractive": markeractive(); break; } Type: WebUI MD5: 8abb41f6e7010d70c90f65fd9a740faa (MarsStealer_Menu.exe) MD5: 03c2c5cb3dba09bfa479fd5c50b5a2cf (dashboard.php) Vuln ID: MVID-2022-0452 Disclosure: 01/15/2022 Exploit/PoC: curl http://MARS_STEALER/mars/panel/includes/markeractions.php --data "func=markeradd&name=/%3C%3Cscript%3Ealert(document.cookie)%3C/script%3E&marker=WWW.MALVULN.com" Disclaimer: The information contained within this advisory is supplied "as-is" with no warranties or guarantees of fitness of use or otherwise.
