These vulnerabilities allows an attacker, who has gained authorized access to the Web-GUI configration, the ability to change configuration or cause the product to be unreliable.

Security and performance is of the utmost importance to D-Link across all product lines. This is not just through the development process but also through regular firmware updates to comply with the current safety and quality standards. We are proactively working with the sources of these reports as well as continuing to review across the complete product line to ensure that the vulnerabilities discovered are addressed. We will continue to update this page to include the relevant product firmware updates addressing these concerns. In the meantime, you can exercise the below cautions to avoid unwanted intrusion into your D-Link product.
Immediate Recommendations for all D-Link router customers
- Do not enable the Remote Management feature since this will allow malicious users to use this exploit from the internet. Remote Management is default disabled on all D-Link Routers and is included for customer care troubleshooting if useful and the customer enables it.
- If you receive unsolicited e-mails that relates to security vulnerabilities and prompt you to action, please ignore it. When you click on links in such e-mails, it could allow unauthorised persons to access your router. Neither D-Link nor its partners and resellers will send you unsolicited messages where you are asked to click or install something.
- Make sure that your wireless network is secure.
- Do not provide your admin password to anyone. If required we suggest updating the password frequently.
The DIR865L router is susceptible to several CSRF attacks, which allow an attacker to forge HTML forms and execute actions in an authorized (logged in) browser session. A malicious attacker can exploit this vulnerability on an unsuspecting device administrator, allowing changes to the administrator credentials and enablement remote management services.
Requirements for the vulneratiblity to be exploited are:
- The victim must have an active logged-in management session with the router.
- The victim must be fooled in to performing an action (e.g., by clicking an attacker provided link), browse to a malicious or compromised site, or be the victim of a man-in-the-middle attack.
Due to the requirement of having to be authenticated (logged in) to the router, the threat of this attack has a very narrow scope so the impact to users is also considered narrow. We also are aware that a exploit to take advantage of the vulnerability is not impossible. In a hardend system, an external user would not have access to excutable commands with-in the router, they should only be accessible by the router's itself, which is configured thru the Web_GUI only.
In order to comply and close this vulnerability D-Link hasl released new firmware (v.1.05b07) that corrects this vulnerability.
