VAR-201404-0469
Vulnerability from variot - Updated: 2025-04-13 23:18The ZyXEL Wireless N300 NetUSB NBG-419N router with firmware 1.00(BFQ.6)C0 allows remote attackers to bypass authentication by using %2F sequences in place of / (slash) characters. ZyXEL Wireless N300 NetUSB Router NBG-419N running firmware version 1.00(BFQ.6)C0, and possibly earlier versions, is susceptible to multiple vulnerabilities. Other device models that use similar firmware may also be vulnerable. The ZyXEL NBG-419N Router is a router device. The ZyXEL NBG-419N Router has a security bypass vulnerability. By bypassing the \"/\" character in the escape URL, the script can be accessed directly. An attacker can exploit these issues to bypass certain security restrictions and execute arbitrary code or commands in the context of the affected device. This may aid in further attacks. ZyXEL Wireless N300 NetUSB NBG-419N is a wireless broadband router product of ZyXEL Technology Company. A remote attacker could exploit this vulnerability to bypass authentication by using the '' sequence instead of '/'
