Zeroshell is a Linux-based network operating system for routers and firewalls. The official FAQ explicitly states: 'The username of the ZeroShell administrator is admin, while the initial password is zeroshell.' The same credentials apply to both the HTTPS web management interface (default LAN IP 192.168.0.75) and SSH. The project reached end-of-life with v3.9.5 in April 2021 and has multiple unpatched RCE vulnerabilities. Default credentials are a known attack vector on internet-exposed deployments.
