Summary

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

Impact

This vulnerability allows for remote exploitation and can lead to severe consequences. The potential impacts include: 1. Unauthorized access: An attacker could gain unauthorized access to the router's system. 2. Data breach: There's a high risk of compromising the confidentiality of data passing through the router. 3. System manipulation: The integrity of the router's operations could be compromised, allowing an attacker to modify settings or redirect traffic. 4. Service disruption: The availability of the router services might be affected, potentially causing network outages. The CVSS v3.1 base score of 8.8 (High) indicates that this is a severe vulnerability with significant potential for harm. The CVSS v4.0 base score of 8.7 (High) further confirms the severity of this vulnerability.

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. Users of the affected D-Link DIR-605L router with firmware version 2.13B01 BETA should check the D-Link support website for any security updates or newer firmware versions that may address this vulnerability.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Limit network exposure: If possible, avoid exposing the router's management interface to the internet. 2. Use strong authentication: Ensure that strong, unique passwords are used for router access. 3. Monitor for suspicious activity: Regularly check router logs for any signs of unusual access or behavior. 4. Network segmentation: Implement network segmentation to limit the potential impact if the router is compromised. 5. Consider alternative firmware: If available and supported, consider using alternative firmware like OpenWrt or DD-WRT that might not be affected by this specific vulnerability. 6. Upgrade hardware: If possible, consider upgrading to a newer router model with more recent security features and regular firmware updates.

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.

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 7.0–10.0 Medium : vulnerabilities with a CVSS base score of 4.0–6.9 Low : vulnerabilities with a CVSS base score of 0.0–3.9 Entries may include additional information provided by organizations and efforts sponsored by CISA. This information may include identifying information, values, definitions, and related links.
