Which versions of Dir 513 Firmware are affected by CVE-2025-70245?

A critical stack buffer overflow vulnerability (CVE-2025-70245) affects D-Link DIR-513 v1.10 devices, allowing unauthenticated remote code execution with a 9.8 CVSS score.

How to fix or mitigate CVE-2025-70245?

Within 24 hours: Inventory all D-Link DIR-513 v1.10 devices in production and isolate them to segregated network segments with restricted internet access. Within 7 days: Implement network-based intrusion detection signatures blocking requests to goform/formSetWizardSelectMode and disable remote management interfaces. Within 30 days: Plan replacement of affected devices with patched firmware versions or alternative vendor equipment, or enforce strict network access controls through firewall rules limiting device exposure.

CRITICAL 9.8

DescriptionCVE.org

Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formSetWizardSelectMode.

AnalysisAI

D-Link DIR-513 router (v1.10) has a stack buffer overflow in the curTime parameter of formSetWizardSelectMode. This is an end-of-life router with no expected patch, meaning exploitation will remain possible indefinitely.

Technical ContextAI

The formSetWizardSelectMode handler does not bounds-check the curTime parameter before copying it to a stack buffer (CWE-787). A sufficiently long input overwrites the return address, enabling attacker-controlled code execution. As a MIPS-based router, exploitation follows well-known MIPS ROP techniques.

RemediationAI

Replace the D-Link DIR-513 with a currently supported router. If replacement is not immediately possible, disable remote management and restrict LAN access to the admin interface.
