VAR-201512-0086
Vulnerability from variot - Updated: 2023-12-18 12:20ZyXEL PMG5318-B20A devices with firmware 1.00AANC0b5 allow remote authenticated users to obtain administrative privileges by leveraging access to the user account. Several models of ZyXEL routers are vulnerable to multiple issues, including weak default passwords, command injections due to improper input validation, and cross-site scripting. ZyXEL PMG5318-B20A There is a vulnerability in the device firmware that can gain administrator privileges. The ZyXEL PMG5318-B20A is a wireless switch from ZyXEL Technology. A remote attacker could exploit this vulnerability to modify the system configuration. Multiple ZyXEL Routers are prone to following security vulnerabilities: 1. An insecure default-password vulnerability 2. Multiple cross-site scripting vulnerabilities 3. A command-execution vulnerability 4. A security-bypass vulnerability 5. An authorization-bypass Successful exploits allow attacker-supplied HTML and script code to run in the context of the affected browser potentially allowing attackers to steal cookie-based authentication credentials, execute arbitrary commands, to gain unauthorized access and bypass security restrictions and perform unauthorized actions
