CVE-2026-2929
Published: 22 February 2026
Summary
CVE-2026-2929 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 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 49.4th 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).
Deeper analysis
CVE-2026-2929 is a stack-based buffer overflow vulnerability affecting the D-Link DWR-M960 router on firmware version 1.01.07. The flaw resides in the function sub_453140 within the file /boafrm/formWlAc of the Wireless Access Control Endpoint component, triggered by manipulation of the submit-url argument. It is classified under CWE-119 and CWE-121.
Remote exploitation is possible by an attacker with low privileges (PR:L), requiring network access with low complexity and no user interaction, per the CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation can compromise confidentiality, integrity, and availability to a high degree, potentially enabling remote code execution on the affected device.
Advisories and additional details are documented in references including VulDB entries (ctiid.347276, id.347276, submit.754503), a GitHub issue at LX-66-LX/cve-new/issues/24, and the D-Link website.
The exploit has been publicly disclosed and may be utilized, heightening the risk for unpatched devices.

Why these techniques?
Stack buffer overflow in public web management interface (formWlAc) with PR:L allows RCE; directly maps to exploiting public-facing apps for initial/privileged access and priv-esc via vulnerable component.

Validating the submit-url argument in the /boafrm/formWlAc Wireless Access Control Endpoint directly prevents the stack-based buffer overflow triggered by malicious input manipulation.
Memory protection mechanisms such as stack canaries, ASLR, and DEP safeguard against stack-based buffer overflows in functions like sub_453140.
Timely flaw remediation through firmware patching directly addresses and corrects the buffer overflow vulnerability in D-Link DWR-M960 version 1.01.07.
