VAR-200708-0019
Vulnerability from variot - Updated: 2025-04-10 23:13Multiple cross-site request forgery (CSRF) vulnerabilities in the management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allow remote attackers to perform certain actions as administrators, as demonstrated by a request to Forms/General_1 with the (1) sysSystemName and (2) sysDomainName parameters. ZyXEL ZyWALL 2 is prone to multiple remote vulnerabilities that affect the management interface. An attacker can exploit these issues to carry out cross-site request forgery, HTML-injection, and denial-of-service attacks. ZyWALL 2 running with firmware V3.62(WK.6) is reported vulnerable to this issue.
