Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formSetWanL2TP function in the /goform/formSetWanL2TP file. This is a buffer overflow vulnerability that can be triggered by manipulating the 'webpage' argument. The vulnerability can be exploited remotely, and an exploit has been publicly disclosed.

Impact

Successful exploitation of this vulnerability could lead to severe consequences. The attacker could potentially gain unauthorized access to the router with high impacts on confidentiality, integrity, and availability of the system. This could result in: 1. Unauthorized access to sensitive information passing through the router 2. Modification or corruption of router configuration and data 3. Disruption of network services, potentially causing a denial of service 4. Use of the compromised router as a pivot point for further attacks on the internal network The vulnerability has a CVSS v3.1 base score of 8.8 (Critical), indicating a high severity level that requires immediate attention.

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 the public disclosure of the exploit, it is crucial to monitor for and apply any security updates or patches as soon as they become available from D-Link.

Mitigation

While awaiting a patch, consider the following mitigation strategies: 1. Limit remote access to the router's management interface, restricting it to trusted IP addresses only. 2. If remote management is not required, disable it completely. 3. Implement strong, unique passwords for router access. 4. Regularly monitor router logs for any suspicious activities. 5. Consider using network segmentation to isolate the vulnerable router from critical network assets. 6. If possible, replace the vulnerable router with a different model or a router from another manufacturer that is not affected by this vulnerability. 7. Keep the router firmware updated with the latest security patches as soon as they become available. 8. Implement additional network security measures such as firewalls and intrusion detection/prevention systems to help detect and prevent potential exploitation attempts.

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.
