| CVE-2019-15800 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2020-08-24 | 10.0 HIGH | 9.8 CRITICAL |
| 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.) | |||||
| CVE-2019-15803 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2020-08-24 | 6.4 MEDIUM | 9.1 CRITICAL |
| An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Through an undocumented sequence of keypresses, undocumented functionality is triggered. A diagnostics shell is triggered via CTRL-ALT-t, which prompts for the password returned by fds_sys_passDebugPasswd_ret(). The firmware contains access control checks that determine if remote users are allowed to access this functionality. The function that performs this check (fds_sys_remoteDebugEnable_ret in libfds.so) always return TRUE with no actual checks performed. The diagnostics menu allows for reading/writing arbitrary registers and various other configuration parameters which are believed to be related to the network interface chips. | |||||
