TITLE

D-Link Technology DIR-605L Buffer Overflow Vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-18479

DESCRIPTION

A stack-based buffer overflow vulnerability exists in D-Link DIR-605L Wireless N300 Cloud Router firmware versions 1.12 and 1.13 via the getAuthCode() function. The flaw arises from unsafe usage of sprintf() when processing user-supplied CAPTCHA data via the FILECODE parameter in /goform/formLogin. A remote unauthenticated attacker can exploit this to execute arbitrary code with root privileges on the device. The D-Link DIR-605L is D-Link's first cloud router, designed for home and small office networks
