Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly validates manipulated inputs like the submit-url argument to prevent buffer overflow exploitation in the /boafrm/formWlEncrypt function.

prevent

Implements memory protections such as stack canaries or DEP to mitigate arbitrary code execution from buffer overflow vulnerabilities.

preventrecover

Requires timely flaw remediation through firmware updates for affected D-Link DIR-822K and DWR-M920 versions to eliminate the buffer overflow vulnerability.

Security SummaryAI

CVE-2025-13552 is a buffer overflow vulnerability (CWE-119, CWE-120) discovered in D-Link DIR-822K and DWR-M920 routers running firmware versions 1.00_20250513164613 and 1.1.50. The flaw affects an unknown function in the /boafrm/formWlEncrypt file and is triggered by manipulating the submit-url argument.

The vulnerability enables remote exploitation over the network with low attack complexity and requires low privileges (PR:L) but no user interaction (CVSS:3.1 score of 8.8; AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). An attacker with such access can achieve high impacts on confidentiality, integrity, and availability, potentially leading to arbitrary code execution on the affected device.

Advisories and details are available in references such as GitHub issues at https://github.com/QIU-DIE/CVE/issues/36 and https://github.com/QIU-DIE/CVE/issues/44, along with VulDB entries at https://vuldb.com/?ctiid.333319, https://vuldb.com/?id.333319, and https://vuldb.com/?submit.693803; no specific patches or mitigations are detailed in the disclosure.

An exploit for this vulnerability has been publicly released, indicating potential for active exploitation.

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?

Buffer overflow vulnerability in the web management interface (/boafrm/formWlEncrypt) of D-Link routers enables remote arbitrary code execution over the network, directly facilitating T1190: Exploit Public-Facing Application.
