Security readout for executives and security teams
Plain-English summary
CVE-2026-2926 affects D-Link DWR-M960 firmware 1.01.07. A remotely reachable LTE configuration function can overflow memory when handling the submit-url argument. The public record says exploit code exists, but there is no KEV listing or cited evidence of active exploitation. Treat exposed or remotely administered devices as urgent to review.
Executive priority
High priority for any environment using DWR-M960 1.01.07, particularly remote sites or carrier-connected devices. The combination of critical impact, remote reachability, and public exploit availability justifies rapid inventory, exposure reduction, and vendor guidance monitoring.
Technical view
The flaw is a stack-based buffer overflow in /boafrm/formLteSetup, function sub_4237AC, in the LTE Configuration Endpoint. The affected input is submit-url. CVSS v2 is 9.0 with network access, low complexity, and single authentication. Reported CWEs are CWE-119 and CWE-121. No remediation version is named in the provided sources.
Likely exposure
Organizations using D-Link DWR-M960 devices on firmware 1.01.07 are potentially exposed, especially where the management or LTE configuration interface is reachable over untrusted networks. The CVSS vector indicates authentication is required, so credential compromise or misuse increases risk.
Exploitation context
The source bundle states an exploit has been published and may be used. The CVSS exploitability field indicates proof-of-concept. However, KEV is false and the provided sources do not establish active exploitation in the wild.
Researcher notes
Evidence is mainly from CVE/VulDB-linked records and a public GitHub issue. The record identifies the affected function and parameter but does not name a fixed firmware. Avoid assuming unauthenticated exploitation; the supplied CVSS vector is Au:S.
Mitigation direction
- Identify all D-Link DWR-M960 devices and firmware versions.
- Check D-Link guidance for firmware updates or official mitigation.
- Remove internet exposure for management and LTE configuration interfaces.
- Restrict access to trusted administrative networks only.
- Review and harden administrative credentials for affected devices.
Validation and detection
- Confirm whether any DWR-M960 runs firmware 1.01.07.
- Verify whether /boafrm/formLteSetup is reachable from untrusted networks.
- Review access logs for unexpected use of LTE configuration pages.
- Check CVE, VulDB, and D-Link pages for updated remediation guidance.
- Document compensating controls for any device awaiting vendor guidance.
