Summary

A critical vulnerability has been discovered in D-Link DIR-619L B1 router firmware version 2.06. The vulnerability affects the formEasySetupWWConfig function in the /goform/formEasySetupWWConfig file. It allows for a buffer overflow attack through manipulation of the curTime argument. This vulnerability can be exploited remotely and has been publicly disclosed.

Impact

This vulnerability has a high severity rating with a CVSS v3.1 base score of 8.8 and a CVSS v4.0 base score of 8.7, both indicating critical severity. The impact is severe across all three main security aspects: 1. Confidentiality: High impact, potentially allowing unauthorized access to sensitive information. 2. Integrity: High impact, possibly enabling attackers to modify or tamper with system data. 3. Availability: High impact, potentially causing system crashes or denial of service. The vulnerability requires low attack complexity and can be initiated remotely with low privileges and no user interaction, making it relatively easy to exploit. This could lead to complete compromise of the affected D-Link router, potentially exposing the entire network to various attacks such as data theft, man-in-the-middle attacks, or use of the router as a pivot point for further network intrusion.

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 provided information, there is no mention of an available patch. Given the critical nature of the vulnerability and its public disclosure, it is crucial to monitor D-Link's official channels for any security updates or patches for the DIR-619L B1 router firmware.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Disable remote administration access to the router if not strictly necessary. 2. Implement strong network segmentation to isolate the vulnerable device. 3. Monitor for any suspicious activities or unauthorized access attempts. 4. If possible, consider replacing the affected D-Link DIR-619L B1 router with a different model or brand that is not vulnerable to this specific exploit. 5. Regularly check for and apply any firmware updates from D-Link as soon as they become available. 6. Implement additional network security measures such as intrusion detection/prevention systems (IDS/IPS) to monitor and block potential exploit attempts.
