Summary

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

Impact

This vulnerability allows for remote exploitation with low attack complexity and minimal privileges required. 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. Given the public disclosure of the exploit, the risk of active exploitation in the wild is significantly increased.

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. Users of the affected D-Link DIR-605L router with firmware version 2.13B01 BETA should monitor for updates from D-Link and apply any security patches as soon as they become available.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Limit network exposure of the affected devices, ideally placing them behind firewalls and not directly exposed to the internet. 2. If possible, disable remote administration features on the router. 3. Implement strong, unique passwords for router access. 4. Regularly monitor for and apply firmware updates from D-Link. 5. Consider using network segmentation to isolate potentially vulnerable devices. 6. Implement intrusion detection/prevention systems to monitor for exploitation attempts. 7. If feasible, consider replacing the affected router with a patched or unaffected model.

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.
