Summary

A critical vulnerability has been discovered in D-Link DIR-605L version 2.13B01 BETA. The vulnerability affects the formSetWAN_Wizard51/formSetWAN_Wizard52 function and is caused by manipulation of the argument curTime, leading to a buffer overflow. This vulnerability can be exploited remotely. The vulnerability is classified as a Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') (CWE-120).

Impact

This buffer overflow vulnerability can have severe consequences. Given its critical nature and high CVSS scores (8.8 for v3.1 and 8.7 for v4.0), the potential impacts include: 1. Unauthorized access: Attackers may gain unauthorized access to the affected D-Link router. 2. Code execution: The buffer overflow could allow attackers to execute arbitrary code on the device. 3. Data breach: With high confidentiality impact, sensitive information stored on or passing through the router could be compromised. 4. System manipulation: The high integrity impact suggests that attackers could modify system files or configurations. 5. Service disruption: The high availability impact indicates that the router's services could be disrupted or made unavailable. 6. Network compromise: As a network device, a compromised router could serve as an entry point for further attacks on the connected network.

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 running firmware version 2.13B01 BETA should monitor D-Link's official channels for security updates and patch announcements.

Mitigation

While waiting for an official patch, consider the following mitigation strategies: 1. Limit access: Restrict remote access to the router's management interface. 2. Network segmentation: Isolate the vulnerable router from critical network segments. 3. Firewall rules: Implement strict firewall rules to filter traffic to and from the affected device. 4. Monitoring: Increase monitoring for suspicious activities related to the router. 5. Alternative firmware: If possible, consider using alternative firmware that may not be affected by this vulnerability. 6. Replace hardware: In critical environments, consider replacing the vulnerable router with a different model or brand that is not affected by this issue. 7. Regular updates: Ensure the router firmware is always updated to the latest version once a patch becomes available. 8. Disable unnecessary services: Turn off any unnecessary services or features that might expose the vulnerability.

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.
