VAR-201410-1357

Vulnerability from variot - Updated: 2025-04-13 23:32

The login page on the ZyXEL SBG-3300 Security Gateway with firmware 1.00(AADY.4)C0 and earlier allows remote attackers to cause a denial of service (persistent web-interface outage) via JavaScript code within unspecified "welcome message" form data that is improperly handled during use for the loginMsg variable's value, a different vulnerability than CVE-2014-7277. ZyXEL SBG-3300 Security Gateway The firmware login page shows service disruption ( permanent Web Interface down ) There are vulnerabilities that are put into a state. The ZyXEL SBG-3300 Security Gateway is a security gateway application. Zyxel SBG-3300 series routers are prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the device to reboot, denying service to legitimate users. Zyxel SBG-3300 V1.00(AADY.4)C0 and prior are vulnerable
