Description
Control Web Panel (CWP) before webpanel_version 1.16 contains an OS command injection vulnerability in the loopback API password change route /newpass/, which runs as root. An attacker can inject arbitrary OS commands by manipulating the POST 'user' parameter that is passed unescaped into a shell command, achieving remote code execution with root privileges.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-77880 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
