Summary

A critical vulnerability has been discovered in the D-Link DIR-619L B1 router, firmware version 2.06. The vulnerability affects the formAdvNetwork function in the /goform/formAdvNetwork file. This issue allows for a buffer overflow attack through the manipulation of the curTime argument. The vulnerability can be exploited remotely, making it particularly dangerous. It has been assigned a CVSS v3.1 base score of 8.8, indicating high severity.

Impact

This vulnerability could have severe consequences if exploited. As a buffer overflow attack, it potentially allows attackers to execute arbitrary code on the affected device. Given the high impact ratings for confidentiality, integrity, and availability, a successful exploit could lead to: 1. Unauthorized access to sensitive information stored or transmitted through the router. 2. Modification or corruption of data, potentially compromising the integrity of network traffic. 3. Disruption of router services, possibly causing network outages. 4. Potential use of the compromised router as a launching point for further attacks on the network. The fact that this vulnerability can be exploited remotely without user interaction increases its severity and the likelihood of exploitation. The CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates that the attack vector is network-based, requires low attack complexity, low privileges, and no user interaction, which makes it relatively easy to exploit.

Exploitation

One proof-of-concept exploit is available on github.com. There is no evidence of proof of exploitation at the moment.

Patch

As of the current information, there is no mention of an available patch for this vulnerability. Users of the affected D-Link DIR-619L B1 router running firmware version 2.06 should monitor D-Link's official channels for security updates and apply them as soon as they become available.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Restrict network access to the router's administration interface, allowing only trusted IP addresses. 2. If possible, disable remote administration features. 3. Regularly monitor router logs for any suspicious activities. 4. Consider using network segmentation to isolate the vulnerable device from critical network assets. 5. If feasible, consider replacing the affected router with a different model that is not vulnerable to this specific attack. 6. Implement strong, unique passwords for router access. 7. Keep the router's firmware updated with the latest available version (while being cautious about the vulnerable version 2.06). 8. Monitor D-Link's official security advisories for updates on this vulnerability and potential patches.

US-CERT Vulnerability Summary for the Week of October 7, 2024
The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week. In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores. Please visit NVD for updated vulnerability entries, which include CVSS scores once they are available. Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. The division of high, medium, and low severities correspond to the following scores: High : vulnerabilities with a CVSS base score of 7.0–10.0 Medium : vulnerabilities with a CVSS base score of 4.0–6.9 Low : vulnerabilities with a CVSS base score of 0.0–3.9 Entries may include additional information provided by organizations and efforts sponsored by CISA. This information may include identifying information, values, definitions, and related links.
