Summary

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

Impact

The impact of this vulnerability is severe, with potential for high compromise of confidentiality, integrity, and availability. Successful exploitation could lead to: 1. Unauthorized access to the router's administrative functions 2. Manipulation or interception of network traffic 3. Potential for remote code execution on the affected device 4. Use of the compromised router as a pivot point for further attacks on the network The CVSS v3.1 base score is 8.8 (Critical), indicating a high severity level. The attack vector is network-based, requires low attack complexity, and no user interaction, making it relatively easy to exploit.

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 current information, there is no mention of an available patch for this vulnerability. D-Link has not yet released an update to address this issue in the DIR-605L firmware version 2.13B01 BETA.

Mitigation

Given the severity of the vulnerability and the lack of an official patch, the following mitigation steps are recommended: 1. Disable remote management access to the router if not absolutely necessary. 2. Implement strong network segmentation to isolate affected devices. 3. Monitor for suspicious activities or unauthorized access attempts on the affected routers. 4. Consider replacing the vulnerable D-Link DIR-605L routers with alternative, secure models 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 to monitor for potential exploitation attempts.

High Vulnerabilities Primary Vendor โ€” Product Description Published CVSS Score Source & Patch Info n/aโ€“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 Ciscoโ€“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/aโ€“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.

US-CERT Vulnerability Summary for the Week of September 30, 2024
The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week. In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores. Please visit NVD for updated vulnerability entries, which include CVSS scores once they are available. Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. The division of high, medium, and low severities correspond to the following scores: High : vulnerabilities with a CVSS base score of 7.0โ€“10.0 Medium : vulnerabilities with a CVSS base score of 4.0โ€“6.9 Low : vulnerabilities with a CVSS base score of 0.0โ€“3.9 Entries may include additional information provided by organizations and efforts sponsored by CISA. This information may include identifying information, values, definitions, and related links.
