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.
