Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formSetEnableWizard function in the /goform/formSetEnableWizard file. By manipulating the curTime argument, an attacker can cause a buffer overflow condition. This vulnerability can be exploited remotely, and public exploit code is available.

Impact

The impact of this vulnerability is severe. It allows for remote code execution with potential for full system compromise. The attacker can gain unauthorized access to the router, potentially leading to: 1. Interception and manipulation of network traffic 2. Use of the compromised router as a pivot point for further attacks on the internal network 3. Modification of router settings to redirect users to malicious websites 4. Installation of malware or backdoors for persistent access 5. Denial of service by crashing the router The CVSS v3.1 base score is 8.8 (High), indicating a critical severity level with high impacts 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 latest information provided, there is no mention of an available patch for this vulnerability. Given the critical nature of the issue and the availability of public exploit code, it is crucial to monitor for any security updates or patches released by D-Link for the DIR-605L router firmware.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Disable remote administration of the router if it's not absolutely necessary. 2. Implement strong network segmentation to isolate affected devices. 3. Monitor for any suspicious activities or unauthorized access attempts on the affected routers. 4. If possible, consider replacing the vulnerable router with a different model or from another vendor that is not affected by this vulnerability. 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 monitor and block potential exploit attempts. 7. Limit network access to the router's management interface to only trusted IP addresses. Given the critical nature of this vulnerability and the availability of public exploit code, addressing this issue should be considered a high priority for your patching and remediation efforts.

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.
