CVE-2024-4509
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 · uneditedA vulnerability was found in Ruijie RG-UAC up to 20240428. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /view/IPV6/naborTable/add_commit.php. The manipulation of the argument ip_addr/mac_addr leads to os command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-263113 was assigned to this vulnerability. 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 confidenceOS command injection vulnerability in Ruijie RG-UAC unified access controller. The add_commit.php file in the IPV6 naborTable functionality accepts user-supplied ip_addr or mac_addr parameters and passes them unsanitized to system shell commands, allowing remote attackers to execute arbitrary OS commands.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm device modelAccess the device's web management interface or check system information pages to identify the exact RG-UAC model number (such as RG-UAC 6000 CC, E10, E10c, E20, E20c, E20m, E50, or E50c).Affected if The device is any of the listed Ruijie RG-UAC 6000 series models.
-
Verify firmware versionNavigate to the device's web interface system settings or use CLI commands (such as 'show version' or 'display device') to retrieve the installed firmware version.Affected if The firmware version matches any of the affected models (all versions of the listed models are vulnerable).
-
Check web interface accessibilityAttempt to access the device's web management interface via HTTP/HTTPS on the typical management ports (commonly port 80 or 443).Affected if The web interface is accessible, indicating the PHP application is running and the vulnerable code is present.
-
Locate vulnerable PHP fileCheck for the presence of the add_commit.php file in the web root or related directories. This file is typically found in paths related to IPv6 functionality.Affected if The file add_commit.php exists on the device's web server.
-
Verify IPv6 neighbor table featureAccess or probe the IPv6 naborTable functionality within the web interface to confirm the feature is enabled and accessible.Affected if The IPv6 neighbor table (naborTable) feature is enabled and accessible through the web interface, exposing the vulnerable parameters ip_addr and mac_addr.
If the device is a Ruijie RG-UAC 6000 series model (CC, E10, E10c, E20, E20c, E20m, E50, or E50c) with an accessible web interface and the IPv6 neighbor table feature is enabled, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation using allowlists for IP and MAC address formats, and replace any system call execution with parameterized alternatives or safe API functions that do not invoke shell interpreters.
