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 network center policy route 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 network center policy route functionality of Synology Router Manager allows authenticated administrators to inject arbitrary web script or HTML via unsanitized input, potentially enabling limited file read/write of non-sensitive data and limited denial-of-service conditions.

MitigationUpgrade Synology Router Manager to version 1.3.1-9346-10 or later to address the XSS vulnerability in the policy route feature.

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 installed SRM version via web interface
    Log into Synology Router Manager (SRM) web interface, go to Control Panel > System > Info, and locate the 'Software' section showing the version number
    Affected if Version is 1.3.0 through 1.3.1-9345 (any build before 1.3.1-9346), or exactly 1.3.1-9346
  2. Identify installed SRM version via command line
    Access the router via SSH and run: `cat /etc/VERSION` or `cat /etc.defaults/VERSION` to retrieve the exact firmware build number
    Affected if The displayed version string falls within the range >= 1.3 and < 1.3.1-9346, or equals 1.3.1-9346 exactly
  3. Verify policy route feature configuration
    In SRM web interface, navigate to Network Center > Policy Route and check if any policy routes are defined or if the feature is accessible
    Affected if Policy route feature exists and is accessible to the administrator account (vulnerability requires authenticated admin access)
  4. Confirm administrator access to network settings
    Log into SRM as an administrator and verify access to Network Center settings where policy route configuration is located
    Affected if Administrator account has permissions to configure policy routes - the XSS payload would be injected through this interface

You are affected if your Synology Router Manager version is 1.3.0 through 1.3.1-9345 or exactly 1.3.1-9346, and you have an administrator account that can access the Network Center policy route feature.
