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
Improper neutralization of input during web page generation ('Cross-site Scripting') vulnerability in WiFi Connect Setting functionality in Synology Router Manager (SRM) before 1.3.1-9346-10 allows remote authenticated users with administrator privileges to read or write specific files containing non-sensitive information and conduct limited denial-of-service attacks by injecting arbitrary web script or HTML.

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

Cross-site scripting (XSS) vulnerability in the WiFi Connect Setting component of Synology Router Manager allows authenticated administrators to inject arbitrary JavaScript or HTML through unsanitized input. The vulnerability enables limited file read/write operations on non-sensitive files and limited DoS attacks.

MitigationUpgrade Synology Router Manager to version 1.3.1-9346-10 or later to obtain the vendor patch for this XSS vulnerability.

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 Synology Router Manager version
    Access the DSM web interface, navigate to Main Menu > Synology Router Manager > Help > About, or run `cat /etc/VERSION` via SSH to retrieve the installed version number.
    Affected if The version displayed is 1.3.0 or any version from 1.3.1 through 1.3.1-9346 (inclusive). Versions below 1.3 or at or above 1.3.1-9346-10 are not affected.
  2. Confirm SRM is the active router firmware
    Verify the device is running Synology Router Manager (SRM) as the operating system, not standard DSM. Check via the web interface header or by running `grep -i 'synology' /etc/VERSION` over SSH.
    Affected if The device runs Synology Router Manager firmware; the vulnerability does not apply to standard DiskStation Manager installations.
  3. Check if WiFi Connect Setting is accessible
    In the SRM web interface, navigate to WiFi Connect or Wireless > WiFi Connect to determine if this component is present and configurable.
    Affected if WiFi Connect Setting component exists and is accessible to administrator accounts, which is required for exploitation.
  4. Verify administrator authentication status
    Confirm you have administrative privileges on the SRM device, as the vulnerability requires an authenticated administrator session.
    Affected if You have valid administrator credentials for the SRM interface, which is required to exploit the XSS in WiFi Connect Setting.

You are affected if your Synology Router Manager version is 1.3.0 through 1.3.1-9346 (inclusive) and an administrator can access the WiFi Connect Setting component.
