Vulnerability from variot
An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Due to lack of input validation in the cmd_sys_traceroute_exec(), cmd_sys_arp_clear(), and cmd_sys_ping_exec() functions in the libclicmd.so library contained in the firmware, an attacker could leverage these functions to call system() and execute arbitrary commands on the switches. (Note that these functions are currently not called in this version of the firmware, however an attacker could use other vulnerabilities to finally use these vulnerabilities to gain code execution.). Zyxel GS1900 There is an input validation vulnerability in the device firmware.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The ZyXEL GS1900 is a managed switch from ZyXEL, Taiwan.
A security vulnerability exists in Zyxel GS1900 using firmware version 2.50 (AAHH.0) prior to C0, which is due to missing input in the 'cmd_sys_traceroute_exec()', 'cmd_sys_arp_clear()', and 'cmd_sys_ping_exec()' functions in the libclicmd.so library Verification check. An attacker could exploit this vulnerability to execute arbitrary code on the switch
