Summary

A critical vulnerability has been identified in D-Link DIR-605L router firmware version 2.13B01 BETA. The vulnerability affects the formWlanSetup function in the /goform/formWlanSetup file. An attacker can manipulate the 'webpage' argument, leading to a buffer overflow condition. This is a classic buffer overflow vulnerability, where input size is not properly checked before copying into a buffer. The vulnerability can be exploited remotely and does not require user interaction.

Impact

This vulnerability allows for remote exploitation without user interaction, potentially leading to severe consequences. The impact is classified as high for confidentiality, integrity, and availability. Successful exploitation could allow an attacker to execute arbitrary code, potentially gaining full control over the affected device. This could lead to unauthorized access to sensitive information, modification of system settings, or disruption of network services. The vulnerability has a CVSS v3.1 base score of 8.8 and a CVSS v4.0 base score of 8.7, both indicating high severity.

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. Given that the vulnerability affects a specific version of the firmware (2.13B01 BETA), it is likely that an updated firmware version will be required to address this issue. Users and administrators should monitor D-Link's official channels for security advisories and firmware updates.

Mitigation

Until a patch is available, consider the following mitigation strategies: 1. Limit network exposure of the affected devices. Place them behind firewalls and isolated from the internet where possible. 2. Implement strong access controls, including complex passwords and restricted administrative access. 3. Monitor for suspicious activities or unauthorized access attempts. 4. Disable remote administration features if not absolutely necessary. 5. Regularly check for and apply firmware updates as soon as they become available from D-Link.

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.
