Summary

A critical vulnerability has been found in D-Link DIR-619L B1 2.06. This issue affects the function formAdvFirewall of the file /goform/formAdvFirewall. The manipulation of the argument curTime leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

This vulnerability could potentially allow attackers to compromise the affected D-Link DIR-619L devices. Given its critical nature and the potential for remote exploitation, successful attacks could lead to unauthorized access, data theft, or use of the device as a pivot point for further network attacks. The vulnerability affects the confidentiality, integrity, and availability of the system, all rated as "HIGH" impact. The attack vector is through the network, requires low attack complexity, and needs no user interaction, making 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

Information about available patches is not provided in the given vulnerability data. The security team should monitor D-Link's official channels for any forthcoming security updates or patches for the DIR-619L model, specifically version 2.06B1.

Mitigation

1. Immediately identify and inventory all D-Link DIR-619L devices, especially those running firmware version 2.06B1, in your network. 2. Closely monitor D-Link's security advisories for updates related to this CVE. 3. Implement network segmentation to isolate potentially vulnerable devices. 4. Strengthen access controls and enhance monitoring for these devices. 5. Be prepared to rapidly apply any security patches as soon as they become available from D-Link. 6. Consider replacing the affected devices with newer models that may have better security features, especially if patches are not forthcoming. 7. If possible, disable or restrict access to the vulnerable formAdvFirewall function until a patch is available. 8. Implement strict input validation for the curTime argument if you have any control over the device's software.

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.
