DescriptionCVE.org

A vulnerability was identified in D-Link DWR-M960 1.01.07. The affected element is the function sub_41914C of the file /boafrm/formWanConfigSetup of the component WAN Interface Setting Handler. The manipulation of the argument submit-url leads to stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is publicly available and might be used.

AnalysisAI

Stack-based buffer overflow in D-Link DWR-M960 firmware versions up to 1.01.07 allows authenticated remote attackers to achieve arbitrary code execution through a malformed submit-url parameter in the WAN interface configuration handler. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker with network access and valid credentials can leverage this to gain complete system compromise.

Technical ContextAI

Classified as CWE-119 (Buffer Overflow). Affects Dwr-M960 Firmware. A vulnerability was identified in D-Link DWR-M960 1.01.07. The affected element is the function sub_41914C of the file /boafrm/formWanConfigSetup of the component WAN Interface Setting Handler. The manipulation of the argument submit-url leads to stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is publicly available and might be used.

RemediationAI

Monitor vendor advisories for a patch. Enable ASLR, DEP/NX, and stack canaries where possible. Restrict network access to the affected service where possible.
