Description
XWEB EVO before 5.6.2 contains a command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary commands as root by exploiting the setuid-root CGI xwconsole.cgi. Attackers can supply malicious input through the sh parameter, which is passed unsanitized to popen(), to achieve full system compromise. This product line reached it's end of service date in March 2026.
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
The records we use list no fixed release for CVE-2026-124010. Check the upstream advisory for a patched version, 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.
