Lifecycle Timeline
4DescriptionCVE.org
A vulnerability was detected in D-Link DIR-605L 2.13B01. Affected by this vulnerability is the function formVirtualServ of the file /goform/formVirtualServ of the component POST Request Handler. The manipulation of the argument curTime results in buffer overflow. The attack can be launched remotely. The exploit is now 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 router allows authenticated remote attackers to achieve code execution through malicious curTime parameter in formVirtualServ function via POST request to /goform/formVirtualServ endpoint. Affects end-of-life product with no vendor support. Publicly available exploit code exists. Attack requires low-privilege authentication but no user interaction, enabling remote compromise of device confidentiality and integrity.
Technical ContextAI
CWE-120 classic buffer overflow in POST request handler's formVirtualServ function. Improper bounds checking on curTime argument enables memory corruption. CVSS PR:L indicates authenticated context required. Affects cpe:2.3:a:d-link:dir-605l:*:*:*:*:*:*:*:* firmware 2.13B01. Vulnerability exploits insufficient input validation in virtual server configuration interface.
RemediationAI
No vendor-released patch identified at time of analysis. D-Link has discontinued support for DIR-605L per end-of-life status confirmed at https://www.dlink.com/. Primary recommendation: replace device with currently supported hardware. Interim mitigations: disable remote administration interfaces, restrict admin access to trusted internal networks only via firewall rules, disable virtual server configuration feature if operationally feasible. Monitor https://vuldb.com/vuln/356533 for community developments. Organizations using affected devices should prioritize hardware replacement due to absence of security updates and publicly available exploit code.
