Summary
CVE-2026-2960 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dwr-M960 Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 4.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires timely remediation of the stack-based buffer overflow flaw through firmware patching or updates specific to CVE-2026-2960.
Implements memory protections like stack canaries, ASLR, and DEP to mitigate exploitation of the stack-based buffer overflow in sub_468D64.
Mandates validation of inputs such as the submit-url argument to prevent buffer overflows in the /boafrm/formDhcpv6s function.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Stack-based buffer overflow in public router web form (/boafrm/formDhcpv6s) with remote unauthenticated-adjacent access and RCE impact directly maps to exploitation of public-facing application.
NVD Description
A flaw has been found in D-Link DWR-M960 1.01.07. Affected by this issue is the function sub_468D64 of the file /boafrm/formDhcpv6s. Executing a manipulation of the argument submit-url can lead to stack-based buffer overflow. The attack can be executed remotely.…

Deeper analysisAI
CVE-2026-2960 is a stack-based buffer overflow vulnerability in the D-Link DWR-M960 router running firmware version 1.01.07. The flaw affects the function sub_468D64 within the file /boafrm/formDhcpv6s, where manipulation of the submit-url argument triggers the overflow. It has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow). The vulnerability was published on 2026-02-23.
The vulnerability enables remote exploitation by an attacker with low privileges, requiring network access and no user interaction. Successful exploitation can result in high-impact confidentiality, integrity, and availability violations, potentially allowing arbitrary code execution on the affected device.
Advisories and details are available via VulDB entries (ctiid.347327, id.347327, submit.754512) and a GitHub issue at LX-66-LX/cve-new/issues/27, which includes a published exploit that may be used. The D-Link website (dlink.com) should be consulted for any vendor-specific patches or mitigation guidance.
