Description

A vulnerability was found in Chengdu Feiyuxing Technology VW2100 and VEC10GP 1.0 B-MB3W202-210825-r11775. This impacts the function handle_wechat_cn_wifi of the file var/html/webserver of the component Weixin Auth Endpoint. The manipulation of the argument extend results in os command injection. The attack can be executed remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

Detection & mitigation playbook

Vulnerability

  1. Detect

    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`).

  2. Remediation status

    The records we use list no fixed release for CVE-2026-124580. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.

  3. 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.
