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
Telesquare TLR-2005KSH 1.1.4 is vulnerable to unauthorized stack overflow vulnerability when requesting admin.cgi parameter with setNtp.

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 · moderate confidence

A critical stack-based buffer overflow vulnerability exists in Telesquare TLR-2005KSH firmware version 1.1.4. The vulnerability is triggered via an unauthenticated HTTP request to the admin.cgi endpoint with the setNtp parameter, allowing remote attackers to overflow the stack and potentially achieve remote code execution.

MitigationApply vendor firmware update when available; until then, isolate the affected device behind a firewall and disable external administrative access to mitigate exploitation.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 device model
    Access the router web interface or check network device information. Look for 'TLR-2005KSH' or 'Telesquare' branding on the login page, or use network scanning to fingerprint the device.
    Affected if The device is a Telesquare TLR-2005KSH router
  2. Determine the firmware version
    Check the router admin interface for a firmware version display (typically in Status, System, or About sections), or query the device via SNMP or API if available.
    Affected if The firmware version is exactly 1.1.4
  3. Verify the admin.cgi endpoint exists
    Attempt to access the admin.cgi endpoint on the router (e.g., http://<router-ip>/admin.cgi or /cgi-bin/admin.cgi).
    Affected if The admin.cgi endpoint is present and responds to requests
  4. Check network exposure of admin interface
    Scan the router's IP for open HTTP/HTTPS ports (80, 443, 8080, 8443) from external networks. Verify if the web administration interface is accessible from untrusted networks.
    Affected if The admin interface is reachable from untrusted/untrusted networks (not just LAN or trusted IPs)
  5. Confirm setNtp parameter handling exists
    If authenticated (or using the vulnerability without auth), probe for the setNtp parameter in admin.cgi. This may be visible in NTP settings page or by inspecting form submissions.
    Affected if The router processes NTP settings through admin.cgi with a setNtp parameter

If the device is a Telesquare TLR-2005KSH running firmware 1.1.4 and the admin.cgi web interface is network-accessible, the environment is affected by CVE-2025-26005.
