CVE-2024-28077Public exploitNetwork attack vector

Login interruption via malformed username handling

Published Aug 26, 2024 · Updated Mar 14, 2025

Denial of service in GL.iNet router firmware allows remote attackers to crash session management through a crafted login username. Session management fails to handle usernames containing unmatched parentheses or brackets and crashes when the login interface receives them. The interface must be network-exposed and requires no authentication; the interruption prevents device logins, with no reported data impact.
