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 20240516 and classified as critical. This issue affects some unknown processing of the file /view/systemConfig/sys_user/user_commit.php. The manipulation of the argument email2/user_name 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-266243. 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

A command injection vulnerability exists in Ruijie RG-UAC's user_commit.php file. Attackers can inject OS commands through the email2 and user_name parameters due to insufficient input sanitization. This remote, high-severity flaw allows arbitrary command execution on the underlying system.

MitigationImplement strict input validation and sanitization on all user-supplied parameters, particularly email2 and user_name. Replace any unsafe shell command execution with parameterized functions or safe APIs that do not pass user input to system shells.

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 Ruijie RG-UAC 6000 product is deployed
    Check system information, web interface banner, or network device inventory to identify the device model as one of the listed RG-UAC 6000 series (C, E10, E10c, E20, E20c, E20m, E50, E50c)
    Affected if The device is identified as any Ruijie RG-UAC 6000 series model from the affected list
  2. Verify user_commit.php exists on the web server
    Attempt to access the path /user_commit.php (or the full path if known for this product) via HTTP/HTTPS request and check for a 200 response or file presence via file system access if available
    Affected if The user_commit.php file is present and accessible via web request
  3. Check if the vulnerable parameters are accepted
    Submit a test HTTP POST or GET request to the user_commit.php endpoint including the email2 and/or user_name parameters with benign test values, observe if the application accepts and processes these parameters
    Affected if The email2 and user_name parameters are accepted and processed by the application without validation errors
  4. Verify the application processes user input in system calls
    If accessible, review the user_commit.php source code or observe application behavior when special characters are submitted in the email2 or user_name parameters to determine if unsanitized input reaches system command execution
    Affected if User input from email2 or user_name parameters is passed to shell execution functions without proper sanitization

If the environment contains a Ruijie RG-UAC 6000 series device and the user_commit.php endpoint is accessible with unvalidated email2 or user_name parameters, the environment is affected by CVE-2024-5337.

Mitigation

Implement strict input validation and sanitization on all user-supplied parameters, particularly email2 and user_name. Replace any unsafe shell command execution with parameterized functions or safe APIs that do not pass user input to system shells.
