A denial-of-service attack in WPA2, and WPA3-SAE authentication methods in D-Link DIR-X1560, v1.04B04, and DIR-X6060, v1.11B04 allows a remote unauthenticated attacker to disconnect a wireless client via sending specific spoofed SAE authentication frames.

Security readout for executives and security teams

Plain-English summary

This issue can let an unauthenticated attacker disrupt Wi-Fi service on specified D-Link routers by forcing wireless clients to disconnect. The main business risk is availability: affected sites may see unreliable wireless access rather than data theft. Public sources do not provide CVSS, exploitation evidence, or detailed vendor remediation in the supplied bundle.

Executive priority

Treat this as a targeted availability risk for affected wireless sites. It does not indicate data compromise in the supplied sources, but unreliable Wi-Fi can disrupt operations. Prioritize asset identification and vendor-guided remediation before broader emergency response.

Technical view

CVE-2021-41753 describes a denial-of-service condition in WPA2 and WPA3-SAE authentication handling on D-Link DIR-X1560 v1.04B04 and DIR-X6060 v1.11B04. The CVE states that spoofed SAE authentication frames can disconnect a wireless client. No CWE, CVSS vector, or confirmed active exploitation is provided.

Likely exposure

Exposure appears limited to organizations using the named D-Link DIR-X1560 or DIR-X6060 firmware versions for wireless access. The attacker must be able to affect wireless authentication traffic, so practical risk is highest for reachable Wi-Fi environments using those devices.

Exploitation context

The supplied CVE data does not show CISA KEV listing or any cited active exploitation. The attack is unauthenticated and availability-focused, but the bundle does not provide exploit maturity, prevalence, or real-world incident evidence.

Researcher notes

Evidence is sparse: the source bundle provides the CVE description, affected model and firmware strings, a D-Link advisory URL, and no CVSS or CWE. Do not assume broader D-Link impact, public exploit availability, or a specific patch without checking the vendor advisory.

Mitigation direction

  • Identify any DIR-X1560 or DIR-X6060 routers and record firmware versions.
  • Review the linked D-Link advisory for supported firmware or replacement guidance.
  • Prioritize replacing unsupported exposed wireless infrastructure.
  • Monitor for repeated unexplained wireless client disconnects.
  • Reduce reliance on affected devices for business-critical Wi-Fi where feasible.

Validation and detection

  • Inventory wireless routers by model and firmware version.
  • Compare findings against DIR-X1560 v1.04B04 and DIR-X6060 v1.11B04.
  • Check whether affected devices provide WPA2 or WPA3-SAE wireless access.
  • Review D-Link advisory SAP10243 for current vendor direction.
  • Correlate helpdesk reports with wireless disconnect patterns.
