Vulnerability from variot
A vulnerability in the TFTP client of Zyxel GS1900 series firmware, XGS1210 series firmware, and XGS1250 series firmware, which could allow an authenticated LAN user to execute arbitrary OS commands via the GUI of the vulnerable device. (DoS) It may be in a state. Zyxel ZyXEL GS1900 is a managed switch from Zyxel, Taiwan.
An access control error vulnerability exists in several Zyxel products. The vulnerability is caused by the product's TFTP client not adding permission control to the function of executing system commands. An attacker can use this vulnerability to execute arbitrary operating system commands after logging in
