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 NTP Region functionality in Synology Router Manager (SRM) before 1.3.1-9346-11 allows remote authenticated users with administrator privileges to inject arbitrary web script or HTML via unspecified vectors.

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 NTP Region functionality of Synology Router Manager (SRM) allows authenticated administrators to inject arbitrary web script or HTML through unspecified vectors, potentially leading to session hijacking or credential theft when other administrators view the affected interface.

MitigationUpgrade Synology Router Manager to version 1.3.1-9346-11 or later to patch the vulnerability. Restrict administrative access to trusted personnel as a defense-in-depth measure.

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. Check installed SRM version
    Access Synology Router Manager web interface, go to Control Panel > System > DSM Update, or run 'grep -i version /etc/*release' via SSH to retrieve the current firmware version
    Affected if Version is 1.3.0 through 1.3.1-9346 (inclusive)
  2. Compare version against safe version
    Verify the full version number against the affected range: versions < 1.3.1-9346 are vulnerable, and version exactly 1.3.1-9346 is also vulnerable; only 1.3.1-9346-11 or later is patched
    Affected if Installed version falls within >= 1.3, < 1.3.1-9346 or equals 1.3.1-9346
  3. Identify NTP Region configuration
    In SRM web interface, navigate to Network Center > Time Server > NTP Region, or check /etc/config/ntp.conf via SSH to see if NTP Region settings are configured
    Affected if NTP Region feature is actively configured or has custom region entries
  4. Audit NTP Region entries for script tags
    Inspect any manually configured NTP region names or custom NTP server entries in Network Center > Time Server for suspicious HTML or JavaScript content
    Affected if Any NTP Region field contains unexpected HTML tags, script elements, or encoded characters that were not entered by the current administrator

User is affected if SRM version is 1.3.0 through 1.3.1-9346 (inclusive) and the NTP Region feature contains injected script content or was accessed by untrusted administrators.
