CVE-2025-3785
Published: 18 April 2025
Summary
CVE-2025-3785 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dwr-M961 Firmware. Its CVSS base score is 8.7 (High).
Operationally, ranked in the top 12.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A stack-based buffer overflow vulnerability, tracked as CVE-2025-3785 and assigned CWE-119 and CWE-121, affects the Authorization Interface component in D-Link DWR-M961 firmware version 1.1.36. The flaw resides in the /boafrm/formStaticDHCP endpoint, where unsanitized input supplied to the Hostname argument can overflow a stack buffer.
An authenticated remote attacker can send a crafted request to trigger the overflow, resulting in arbitrary code execution or denial of service with high impact to confidentiality, integrity, and availability. The CVSS 4.0 score of 8.7 reflects network attack vector, low attack complexity, and low privileges required, and a working exploit has already been published.
Vendor guidance and public references recommend upgrading to firmware version 1.1.49 to remediate the issue; the D-Link advisory and VulDB entries provide the official patch information.
The associated EPSS score rose from low values at disclosure to a peak of 0.0504 on 2026-05-27 before receding to the current 0.0347, indicating that exploitation interest increased after the vulnerability became public.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
