LibreNMS 23.10.0 before 26.4.0 OS Command Injection via Hostname
LibreNMS versions >= 23.10.0 and < 26.2.0 (fixed in 26.4.0) contain an authenticated OS command injection vulnerability in libvirt discovery. When libvirt support is enabled (enable_libvirt=true), the device hostname ($this->getDevice()->hostname) is concatenated into shell commands (ssh, virsh list/dumpxml/domstate) in VminfoLibvirt.php and passed to exec() without escapeshellarg() or argument separation. An authenticated admin can set a crafted device hostname to inject arbitrary OS commands, leading to remote code execution in the discovery worker context.
