Technical ContextAI · show details

A denial-of-service issue was discovered on certain GL-iNet devices. Some websites can detect devices exposed to the external network through DDNS, and consequently obtain the IP addresses and ports of devices that are exposed. By using special usernames and special characters (such as half parentheses or square brackets), one can call the login interface and cause the session-management program to crash, resulting in customers being unable to log into their devices. This affects MT6000 4.5.6, XE3000 4.4.5, X3000 4.4.6, MT3000 4.5.0, MT2500 4.5.0, AXT1800 4.5.0, AX1800 4.5.0, A1300 4.5.0, S200 4.1.4-0300, X750 4.3.7, SFT1200 4.3.7, MT1300 4.3.10, AR750 4.3.10, AR750S 4.3.10, AR300M 4.3.10, AR300M16 4.3.10, B1300 4.3.10, MT300N-V2 4.3.10, and XE300 4.3.16. Affected products include: Gl-Inet Mt6000 Firmware, Gl-Inet X3000 Firmware, Gl-Inet Xe3000 Firmware, Gl-Inet A1300 Firmware, Gl-Inet Ax1800 Firmware.
