Vulnerabilidades de Microhard Systems

Microhard Systems IPn4G 1.1.0 contains multiple authenticated remote code execution vulnerabilities in the admin interface that allow attackers to create crontab jobs and modify system startup scripts. Attackers can exploit hidden admin features to execute arbitrary commands with root privileges, including starting services, disabling firewalls, and writing files to the system.

Microhard Systems IPn4G 1.1.0 contains hardcoded default credentials that cannot be changed through normal gateway operations. Attackers can exploit these default credentials to gain unauthorized root-level access to the device by logging in with predefined username and password combinations.

Microhard Systems IPn4G 1.1.0 contains an undocumented vulnerability that allows authenticated attackers to list and manipulate running system processes. Attackers can send arbitrary signals to kill background processes and system services through a hidden feature, potentially causing service disruption and requiring device restart.

Microhard Systems IPn4G 1.1.0 contains an authentication bypass vulnerability in the hidden system-editor.sh script that allows authenticated attackers to read, modify, or delete arbitrary files. Attackers can exploit unsanitized 'path', 'savefile', 'edit', and 'delfile' parameters to perform unauthorized file system modifications through GET and POST requests.

Microhard Systems IPn4G 1.1.0 contains a service vulnerability that allows authenticated users to enable a restricted SSH shell with a default 'msshc' user. Attackers can exploit a custom 'ping' command in the NcFTP environment to escape the restricted shell and execute commands with root privileges.
