Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formSetEasy_Wizard function in the /goform/formSetEasy_Wizard file. By manipulating the curTime argument, an attacker can cause a buffer overflow. This is a remote attack vector that doesn't require user interaction.

Impact

This vulnerability could allow an attacker to execute arbitrary code on the affected device, potentially leading to complete system compromise. The impact is severe, with high risks to confidentiality, integrity, and availability of the system. An attacker could potentially gain unauthorized access to sensitive information, modify system configurations, or disrupt network operations. Given the nature of the device (a router), this could also serve as an entry point for further attacks on the network.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

As of the current information, there is no mention of an available patch. The vulnerability has been publicly disclosed, which increases the urgency for a patch or mitigation measures.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Disable remote administration of the router if it's not necessary. 2. Implement strong access controls and use a firewall to limit access to the device's web interface. 3. Monitor for suspicious activities or unauthorized access attempts. 4. If possible, consider replacing the affected device with a different model or from another vendor that is not vulnerable to this specific issue. 5. Regularly check for firmware updates from D-Link and apply them as soon as they become available.

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.
