What to do

AI-suggested

To mitigate CVE-2025-67113, organizations should immediately restrict access to the ACS endpoints by implementing network segmentation, firewall rules, and VPNs to ensure only trusted management systems can communicate with the CWMP client. Monitoring and logging of TR-069 traffic should be enhanced to detect anomalous or unexpected firmware download requests. Until an official firmware patch is released, consider disabling remote firmware upgrades or replacing affected devices with alternatives that do not expose this vulnerability. Vendors and integrators should prioritize releasing and deploying firmware updates that properly sanitize and escape the Download URL parameter to prevent command injection. Additionally, implement strict input validation and employ security best practices such as running CWMP clients with least privilege where feasible. Regular vulnerability scanning and penetration testing focused on TR-069 interfaces can help identify exploitation attempts. Finally, educate network administrators about the risks of exposing ACS endpoints to untrusted networks.

Description

OS command injection in the CWMP client (/ftl/bin/cwmp) of Small Cell Sercomm SCE4255W (FreedomFi Englewood) firmware before DG3934v3@2308041842 allows remote attackers controlling the ACS endpoint to execute arbitrary commands as root via a crafted TR-069 Download URL that is passed unescaped into the firmware upgrade pipeline.
