Summary

A critical vulnerability has been discovered in D-Link DIR-605L router firmware version 2.13B01 BETA. This vulnerability affects the formSetWizard1/formSetWizard2 function and is related to a buffer overflow issue. The vulnerability can be exploited by manipulating the 'curTime' argument, potentially leading to a buffer overflow condition. This is a remote attack vector, meaning an attacker does not need physical access to the device to exploit this vulnerability.

Impact

The impact of this vulnerability is severe, with a CVSS v3.1 base score of 8.8 (high severity). It affects all three main aspects of security: 1. Confidentiality: High impact, potentially allowing unauthorized access to sensitive information. 2. Integrity: High impact, possibly allowing an attacker to modify or corrupt data. 3. Availability: High impact, which could result in denial of service or system crashes. This network-based attack has low complexity and requires no user interaction. An attacker with low privileges can potentially exploit this vulnerability to gain unauthorized access, manipulate data, or disrupt services on affected D-Link DIR-605L routers. The vulnerability is classified as a buffer overflow (CWE-120), which is a common and dangerous type of security flaw. It allows attackers to potentially execute arbitrary code, crash the system, or cause other unintended behavior.

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 provided information, there is no mention of an available patch. Given that the vulnerability affects a specific beta version (2.13B01 BETA) of the D-Link DIR-605L router firmware, it is crucial to check with D-Link for any security updates or newer firmware versions that may address this issue.

Mitigation

While waiting for an official patch, consider the following mitigation strategies: 1. Limit network exposure: If possible, avoid exposing the management interface of the D-Link DIR-605L router to the internet. 2. Use strong access controls: Implement strong, unique passwords for router access. 3. Monitor for suspicious activities: Keep an eye on router logs for any unusual access attempts or behaviors. 4. Consider alternative firmware: If available and feasible, consider using alternative firmware that may not be affected by this vulnerability. 5. Network segmentation: Isolate the affected routers in a separate network segment to limit potential impact. 6. Regular updates: Keep checking for and apply any firmware updates from D-Link as soon as they become available. 7. Replace if necessary: If no patch is forthcoming and the risk is deemed too high, consider replacing the affected routers with alternative models not subject to this 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.
