CVE-2023-4382Public exploitNetwork attack vector

Authenticated stored XSS via unsanitized avatar value

Published Aug 16, 2023 · Updated Nov 21, 2024

Stored cross-site scripting in TDevs Hyip Rio 2.1 allows remote authenticated users to execute script in another user's browser. The /user/settings Profile Settings handler places the attacker-controlled avatar value into generated page content without neutralizing script syntax. A registered account and a separate user's viewing of the stored content are required; successful exploitation alters browser-rendered content.
