Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was found in Ruijie RG-UAC up to 20240428 and classified as critical. This issue affects some unknown processing of the file /view/IPV6/ipv6StaticRoute/static_route_add_ipv6.php. The manipulation of the argument text_prefixlen/text_gateway/devname leads to os command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-263111. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OS command injection vulnerability in Ruijie RG-UAC unified access control device. The ipv6StaticRoute functionality in static_route_add_ipv6.php passes user-supplied parameters (text_prefixlen, text_gateway, devname) directly to system shell commands without sanitization, allowing arbitrary OS command execution. Attack is remote and a public exploit exists.

MitigationSince vendor did not respond and no patch is available, implement network segmentation to isolate the device, deploy WAF rules to detect/block command injection patterns in HTTP parameters, and monitor for indicators of compromise. Consider disabling IPv6 static route functionality if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device is Ruijie RG-UAC
    Access the device web interface or check system information via CLI (show system-info or similar vendor command). Look for model number indicating RG-UAC 6000 series (CC, E10, E10c, E20, E20c, E20m, E50, E50c).
    Affected if Device is a Ruijie RG-UAC 6000 series model and the ipv6StaticRoute feature is accessible or has been accessed.
  2. Identify firmware version
    Check the device firmware version through web interface (usually under System > Firmware or System > Version) or via CLI command like 'show version' or 'get system info'.
    Affected if Firmware version is any version on the affected models (all versions of the listed models are affected).
  3. Verify IPv6 static route functionality is present
    Navigate to the static routing configuration page in the web interface, specifically look for IPv6 static route settings (static_route_add_ipv6.php). Check if the file exists on the device filesystem via CLI access if available.
    Affected if The static_route_add_ipv6.php file exists and the IPv6 static route configuration interface is accessible or was previously configured.
  4. Check for unauthorized commands or scripts
    Review device logs, especially web access logs and system command logs. Look for unusual commands, unexpected network connections, or suspicious processes. Search for indicators like shell metacharacters (; | & $`) in HTTP request logs targeting the static route pages.
    Affected if Logs show command injection patterns (shell metacharacters) in requests to static_route_add_ipv6.php, or unexpected commands have been executed on the system.
  5. Inspect for backdoors or persistence
    Check for new user accounts, scheduled tasks, cron jobs, or startup scripts that may have been created. Review /etc/passwd, /etc/crontab, and startup configuration files if CLI access is available.
    Affected if Unauthorized accounts, scripts, or scheduled tasks exist on the device that were not configured by the administrator.

A user is affected if they operate a Ruijie RG-UAC 6000 series device (any firmware version) with the IPv6 static route functionality exposed, particularly if the device is directly accessible from network or has been targeted by remote attacks.
