Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. The issue affects the formWlanSetup_Wizard function in the /goform/formWlanSetup_Wizard file. This vulnerability allows for a buffer overflow attack through the manipulation of the 'webpage' argument. The attack can be initiated remotely, and the exploit has been publicly disclosed.

Impact

This vulnerability could allow an attacker to execute arbitrary code on the affected D-Link DIR-605L routers. Given the critical nature and the high impact on confidentiality, integrity, and availability, successful exploitation could lead to complete compromise of the device. Attackers might be able to: 1. Gain unauthorized access to the router's administration interface 2. Modify router configurations 3. Intercept or manipulate network traffic 4. Use the compromised router as a pivot point for further attacks on the network 5. Cause denial of service by crashing the device The fact that this vulnerability can be exploited remotely with low attack complexity increases the likelihood of widespread attacks. The CVSS v3.1 base score is 8.8 (High), with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating high impact on confidentiality, integrity, and availability.

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 that the affected firmware version is labeled as BETA (2.13B01 BETA), it's possible that D-Link may release a patched version in the future. However, users should not rely on this assumption and should take immediate mitigation steps.

Mitigation

Until a patch is available, the following mitigation steps are recommended: 1. Disable remote administration access to the router if it's not absolutely necessary. 2. Implement strong network segmentation to isolate potentially vulnerable devices. 3. Monitor for any suspicious activities or unauthorized access attempts on the affected routers. 4. Consider replacing the affected D-Link DIR-605L routers with alternative, non-vulnerable devices if possible. 5. Regularly check for firmware updates from D-Link and apply them as soon as they become available. 6. Implement additional network security measures such as intrusion detection/prevention systems (IDS/IPS) to detect and block potential exploit attempts. 7. Limit network exposure of the affected devices by placing them behind firewalls and ensuring they are not directly accessible from the internet. Given the critical nature of this vulnerability and its potential impact, addressing this issue should be considered a high priority for the security team.
