CVE-2024-56517

17
FAUCET Score

CVE-2024-56517 describes a reflected cross-site scripting (XSS) vulnerability in LGSL (Live Game Server List) versions up to and including 6.2.1. This flaw allows attackers to inject arbitrary JavaScript code via the Referer HTTP header, which is then reflected in the HTML response without proper sanitization. Rated Medium (CVSS 5.3), the vulnerability requires user interaction (UI:P) but has a low attack complexity (AC:L) and no prerequisites (PR:N), potentially leading to client-side script execution. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
