GHSA-rchw-322g-f7rm osctrl is Vulnerable to OS Command Injection via Environment Configuration

• Go github.com/jmpsec/osctrl: < 0.5.0 → fixed in 0.5.0

Summary An OS command injection vulnerability exists in the `osctrl-admin` environment configuration. An authenticated administrator can inject arbitrary shell commands via the hostname parameter when creating or editing environments. These commands are embedded into enrollment one-liner scripts generated using Go's `text/template` package (which does not perform shell escaping) and execute on every endpoint that enrolls using the compromised environment. Impact An attacker with administrator access can achieve remote code execution on every endpoint that enrolls using the compromised environment. Commands execute as root/SYSTEM (the privilege level used for osquery enrollment) before osquery is installed, leaving no agent-level audit trail. This enables backdoor installation, credential exfiltration, and full endpoint compromise. Patches Fixed in osctrl `v0.5.0`. Users should upgrade immediately. Workarounds Restrict osctrl administrator access to trusted personnel. Review existing environment configurations for suspicious hostnames. Monitor enrollment scripts for unexpected commands.
