Summary

A critical vulnerability has been identified in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formEasySetupWizard/formEasySetupWizard2 function in the /goform/formEasySetupWizard file. By manipulating the 'curTime' argument, an attacker can trigger a buffer overflow condition. This is classified as a classic buffer overflow vulnerability (CWE-120). The vulnerability can be exploited remotely and requires low attack complexity and only low privileges. It has a CVSS v3.1 base score of 8.8 (High severity), indicating a significant risk to affected devices.

Impact

The impact of this vulnerability is severe. If successfully exploited, it can lead to high impacts on confidentiality, integrity, and availability of the affected system. Attackers could potentially execute arbitrary code, gain unauthorized access to sensitive information, or cause system crashes. The vulnerability allows for remote exploitation, which increases its potential impact. Given the low attack complexity and low privileges required, it poses a significant threat to the security of affected D-Link DIR-605L routers.

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 latest information provided, there is no mention of an available patch. The vulnerability is in a BETA version of the firmware (2.13B01 BETA), which suggests that D-Link may be working on a stable release that addresses this issue. However, until an official patch is released, the device remains vulnerable. The security team should regularly check D-Link's official website or support channels for firmware updates and apply them as soon as they become available.

Mitigation

Given the severity of the vulnerability and the lack of an official patch, the following mitigation steps are recommended: 1. Disable remote administration of the router if it's not absolutely necessary. 2. Implement strong network segmentation to isolate vulnerable devices. 3. Monitor for any suspicious activities or unauthorized access attempts. 4. Consider replacing the affected D-Link DIR-605L routers with alternative, secure devices if possible. 5. Regularly check D-Link's official website or support channels for firmware updates and apply them as soon as they become available. 6. Implement additional network security measures such as firewalls and intrusion detection systems to help detect and prevent exploitation attempts. 7. Limit network exposure of the affected devices to trusted networks only. 8. Apply the principle of least privilege to all systems and services that interact with the vulnerable routers.

Vulnerability Summary for the Week of September 30, 2024
High Vulnerabilities Primary Vendor — Product Description Published CVSS Score Source & Patch Info n/a–n/a An issue was discovered in Atos Eviden iCare 2.7.1 through 2.7.11. The application exposes a web interface locally. In the worst-case scenario, if the application is remotely accessible, it allows an attacker to execute arbitrary commands with system privilege on the endpoint hosting the application, without any authentication. 2024-09-30 10 CVE-2024-42017 cve@mitre.org cve@mitre.org Cisco–Cisco Data Center Network Manager A vulnerability in the REST API and web UI of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to perform a command injection attack against an affected device. This vulnerability is due to improper user authorization and insufficient validation of command arguments. An attacker could exploit this vulnerability by submitting crafted commands to an affected REST API endpoint or through the web UI. A successful exploit could allow the attacker to execute arbitrary commands on the CLI of a Cisco NDFC-managed device with network-admin privileges. Note: This vulnerability does not affect Cisco NDFC when it is configured for storage area network (SAN) controller deployment. 2024-10-02 9.9 CVE-2024-20432 ykramarz@cisco.com n/a–n/a The WebDAV service in Infinera TNMS (Transcend Network Management System) 19.10.3 allows a low-privileged remote attacker to conduct unauthorized file operations, because of execution with unnecessary privileges.
