Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly remediates the stack-based buffer overflow in sub_46385C of /boafrm/formDosCfg by applying vendor firmware patches or updates.

prevent

Enforces validation of the submit-url argument to restrict operations within memory bounds and prevent the buffer overflow.

prevent

Deploys memory safeguards like stack canaries, ASLR, and DEP to protect against remote exploitation of the stack-based buffer overflow.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Stack-based buffer overflow in the router's web management form handler (/boafrm/formDosCfg) is a remotely exploitable flaw in an internet-facing application. Low-privilege authenticated network access is sufficient to trigger arbitrary code execution and full device compromise, directly mapping to T1190.

Deeper analysisAI

CVE-2026-2882 is a stack-based buffer overflow vulnerability affecting the D-Link DWR-M960 router on firmware version 1.01.07. The issue is located in the function sub_46385C within the file /boafrm/formDosCfg, where manipulation of the submit-url argument triggers the overflow. Published on 2026-02-21, it is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow).

Attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction, provided they possess low privileges (PR:L). The CVSS v3.1 score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates high impacts on confidentiality, integrity, and availability, enabling potential full compromise of the affected device.

Advisories on VulDB and a GitHub issue (LX-66-LX/cve-new/issues/16) document the vulnerability and note that a public exploit exists which could be used. The D-Link website is referenced for further details, though specific patch information is not detailed in available sources.
