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
RG-EG series gateway EG350 EG_RGOS 11.1(6) was discovered to contain a SQL injection vulnerability via the function get_alarmAction at /alarm_pi/alarmService.php.

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

SQL injection vulnerability in the get_alarmAction function of /alarm_pi/alarmService.php on RG-EG350 gateways running EG_RGOS 11.1(6). An attacker can inject malicious SQL queries via HTTP requests to the alarmService endpoint, potentially allowing unauthorized database access, data exfiltration, or compromise of the gateway device.

MitigationApply vendor firmware patch when available; until then, restrict network access to the web management interface, implement WAF rules to detect SQL injection patterns, and monitor for suspicious requests to alarmService.php.

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. Identify the RG-EG350 gateway model
    Log into the device web interface or check the device label/model number to confirm the hardware is an RG-EG350 gateway
    Affected if The device is not an RG-EG350 model, the detection does not apply
  2. Check the installed firmware version
    Access the web management interface, navigate to System Status or About page to view the firmware version. Alternatively, use CLI command 'show version' or check the startup banner
    Affected if The firmware version is exactly EG_RGOS 11.1(6)
  3. Verify the alarmService.php endpoint exists
    Attempt to access the URI /alarm_pi/alarmService.php on the device's web server (e.g., http://<device-ip>/alarm_pi/alarmService.php)
    Affected if The endpoint returns a response (200, 404, or any HTTP response rather than a connection timeout), indicating the PHP file is present and reachable
  4. Confirm the web management interface is exposed
    Verify that the device's HTTP/HTTPS management interface is accessible from the network by attempting a connection to ports 80 or 443
    Affected if The web interface is reachable from network segments where untrusted users could send requests

You are affected if you have an RG-EG350 gateway running exactly firmware EG_RGOS 11.1(6) with the alarmService.php endpoint accessible on the network.

Mitigation

Apply vendor firmware patch when available; until then, restrict network access to the web management interface, implement WAF rules to detect SQL injection patterns, and monitor for suspicious requests to alarmService.php.
