Lifecycle Timeline
4DescriptionCVE.org
A vulnerability has been found in D-Link DIR-605L 2.13B01. This affects the function formAdvFirewall of the file /goform/formAdvFirewall of the component POST Request Handler. Such manipulation of the argument curTime leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Buffer overflow in D-Link DIR-605L 2.13B01 wireless router enables remote authenticated attackers to execute arbitrary code via the formAdvFirewall function in POST request handler. Exploitation occurs through manipulation of the curTime parameter in /goform/formAdvFirewall endpoint. Publicly available exploit code exists. This end-of-life product receives no vendor security support, requiring immediate device replacement for affected deployments.
Technical ContextAI
CWE-120 classic buffer overflow in formAdvFirewall function caused by unchecked curTime parameter length validation. POST request handler fails to enforce boundary checks before copying user-controlled input into fixed-size memory buffer. CVSS vector PR:L indicates authenticated access requirement. Affects DIR-605L firmware 2.13B01 (cpe:2.3:a:d-link:dir-605l).
RemediationAI
No vendor-released patch identified at time of analysis. D-Link has discontinued support for DIR-605L hardware, making security updates unavailable. Primary remediation: immediately replace affected DIR-605L devices with currently supported router models from D-Link or alternative vendors. Interim risk reduction for environments unable to replace immediately: disable remote administration interfaces, restrict administrative access to trusted internal networks only via firewall rules, implement network segmentation to isolate vulnerable devices, and monitor for unauthorized configuration changes.
