The CVE-2024-23629 is a critical security vulnerability discovered in the web component of the Motorola MR2600 router. This vulnerability, identified and published by Exodus Intelligence on January 25, 2024, allows an attacker to bypass authentication mechanisms, potentially accessing protected URLs and retrieving sensitive information. The issue is present in version 1.0.7 of the router's firmware.

The vulnerability has been classified under CWE-287 for Improper Authentication and is associated with CAPEC-115 Authentication Bypass. The CVSS 3.1 scoring for this vulnerability is a high-risk 9.6, indicating a critical impact on confidentiality, integrity, and availability.

Technical Details

According to the CVSS metrics, the attack complexity is low, and the attack vector is limited to the adjacent network. No authentication or user interaction is required to exploit this vulnerability, making it particularly dangerous. The impact on affected systems includes:

• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

The vector string for this vulnerability is CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H.

Mitigation Strategies

Mitigating the CVE-2024-23629 vulnerability requires a proactive approach to ensure your Motorola MR2600 router remains secure. Below are recommended steps to mitigate the risk:

• Update Firmware: The most effective mitigation strategy is to update the router's firmware to a version that addresses this vulnerability. Check Motorola's official website or contact their support for the latest firmware updates.
• Network Segmentation: Isolate the vulnerable device from critical networks. Network segmentation can significantly reduce the attack surface.
• Access Control Lists (ACLs): Employ ACLs to restrict access to the router’s web interface, ensuring only trusted IP addresses can communicate with the device.
• Disable Unnecessary Services: Disable the web interface if it is not needed or restrict its use to local management only.

Conclusion

The CVE-2024-23629 vulnerability poses a significant threat to systems using the Motorola MR2600 router with version 1.0.7 firmware. By promptly updating the firmware, implementing network segmentation, using ACLs, and disabling unnecessary services, organizations can mitigate the risks associated with this vulnerability.
