Reflected XSS via unencoded Referer attribute
Published Dec 30, 2024 · Updated Dec 30, 2024
Reflected XSS in tltneon LGSL (Live Game Server List) 6.2.1 and earlier allows remote attackers to execute JavaScript via a crafted Referer header. When the preloader is enabled, lgsl_files/lgsl_list.php assigns HTTP_REFERER directly to $uri and emits it in an HTML attribute without encoding. Exploitation requires a user to load or reload the affected response; the injected script runs within the LGSL browser origin and can read or alter page data available there.
