Description Preview
Overview
The MoFi Network MOFI4500-4GXeLTE-V2 router contains an authentication bypass vulnerability that affects firmware version 3.5.6-xnet-5052. When exploited, this vulnerability allows attackers to send specially crafted HTTP requests that circumvent the router's authentication mechanisms. Once authentication is bypassed, an attacker can execute arbitrary code on the device, potentially leading to full control of the router. This could allow attackers to modify network configurations, intercept network traffic, use the router as a pivot point for further attacks, or compromise connected devices. This vulnerability is particularly severe as it requires no user interaction and could be exploited remotely.
Remediation
To mitigate this vulnerability, users should:
- Update the router firmware to the latest version as provided by MoFi Network if a patch is available.
- If no patch is available, consider implementing network-level protections:
- Place the router behind another firewall if possible
- Restrict remote access to the router's management interface
- Configure access control lists to limit which IP addresses can access the router
- Monitor for suspicious access attempts to the router
- Change default credentials on all network devices
- Regularly check the MoFi Network website for security updates and patches
- Consider network segmentation to limit potential damage if the router is compromised
