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
Heap-based Buffer Overflow vulnerability in TP-Link Archer AX53 v1.0 (tmpserver modules) allows authenticated adjacent attackers to cause a segmentation fault or potentially execute arbitrary code via a specially crafted set of network packets containing an excessive number of host entries This issue affects Archer AX53 v1.0: through 1.3.1 Build 20241120.

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

Heap-based buffer overflow in the tmpserver module of TP-Link Archer AX53 v1.0 allows authenticated adjacent attackers to send specially crafted network packets containing excessive host entries, overflowing the heap buffer and potentially enabling code execution or causing denial of service via segmentation fault.

MitigationApply vendor firmware updates when available; otherwise, restrict adjacent network access and enforce strong authentication to limit attack surface.

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. Confirm device model and firmware version
    Access the router's web management interface (typically at 192.168.0.1) or via SSH and navigate to the Firmware Upgrade or System settings section to view the exact firmware version
    Affected if The firmware version is exactly 1.0 (1.0.x or 1.0 build numbers)
  2. Verify tmpserver module accessibility
    Check if the tmpserver functionality is accessible on the device by examining the web interface or attempting to access common tmpserver endpoints (often port 8080 or /tmpserver paths)
    Affected if The tmpserver module is exposed and responds to requests from the local network
  3. Check remote management settings
    Examine the router's Administration or Management settings to determine if remote/adjacent network access to the tmpserver is enabled, particularly looking for settings like 'Enable Remote Management' or 'Allow Remote Access'
    Affected if Remote or adjacent network access to the management interface is enabled and accessible from non-LAN segments
  4. Identify authentication exposure
    Review the router's access control and authentication settings to determine if default credentials are in use or if the administrative interface is accessible without strong authentication from the local network
    Affected if The router allows unauthenticated or weakly authenticated access to the tmpserver functionality from adjacent network segments

The device is affected if it is a TP-Link Archer AX53 running firmware version 1.0 with the tmpserver module accessible from the adjacent network without proper access controls.

Mitigation

Apply vendor firmware updates when available; otherwise, restrict adjacent network access and enforce strong authentication to limit attack surface.

Recommended fix Moderate confidence

Latest available Archer AX53 v1.0 firmware (verify on TP-Link support website)

  1. 1. Identify the current firmware version of the TP-Link Archer AX53 v1.0 by accessing the router's web management interface or checking the device label.
  2. 2. Navigate to the TP-Link support website (www.tp-link.com) and search for the Archer AX53 firmware downloads section.
  3. 3. Download the latest available firmware version for the Archer AX53 v1.0.
  4. 4. Access the router's web management interface, go to the Administration > Firmware Upgrade section.
  5. 5. Upload and apply the downloaded firmware file, ensuring the device remains powered on during the update process.
  6. 6. After the firmware update completes, verify the new firmware version matches the latest available release.
Caveat Firmware updates typically require a brief downtime; ensure no critical network operations are in progress
