Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formEasySetupWWConfig function in the /goform/formEasySetupWWConfig file. The issue arises from improper input validation of the 'curTime' argument, which can lead to a buffer overflow condition. This vulnerability allows for remote exploitation and can be launched without user interaction. The exploit has been publicly disclosed.

Impact

This vulnerability allows for remote exploitation and can have severe consequences. An attacker can potentially execute arbitrary code with elevated privileges, leading to complete system compromise. The impact includes: 1. Unauthorized access: Attackers may gain control over the affected router. 2. Data breach: Confidential information passing through the router could be intercepted or stolen. 3. Network manipulation: The compromised router could be used as a pivot point for further attacks on the internal network. 4. Denial of Service: The buffer overflow could crash the router, disrupting network services. The vulnerability has been assigned a CVSS v3.1 base score of 8.8 (High severity), indicating a significant risk.

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, no specific patch has been mentioned for this vulnerability. Users of D-Link DIR-605L routers running firmware version 2.13B01 BETA should check the D-Link support website for any available updates or security advisories.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Limit remote access: Disable remote management of the router if not strictly necessary. 2. Use strong authentication: Implement strong, unique passwords for router access. 3. Network segmentation: Isolate the vulnerable router from critical network segments. 4. Monitor for suspicious activity: Implement network monitoring to detect potential exploitation attempts. 5. Consider alternative firmware: If possible, consider using alternative firmware solutions that may not be affected by this vulnerability. 6. Regular updates: Keep checking for and apply any firmware updates from D-Link 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.

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.
