AI-suggested
- Immediately restrict access to the /admin/upload-custom-firmware endpoint to only trusted administrators using network segmentation and strong access controls.
- Implement multi-factor authentication (MFA) for all accounts with access to the firmware upload feature to reduce risk from credential compromise.
- Apply strict input validation and sanitization on all user-controlled parameters (filename, port, baud_rate, core, autoreset) to prevent command injection.
- Monitor logs for unusual activity related to firmware uploads or command execution attempts.
- If possible, disable the firmware upload feature until a vendor patch or official fix is available.
- Conduct regular audits of user accounts and permissions to ensure only necessary personnel have upload privileges.
- Deploy network intrusion detection systems (NIDS) with rules targeting suspicious command injection patterns.
- Stay informed on vendor advisories and apply patches promptly once released.
- Consider deploying application-layer firewalls or web application firewalls (WAFs) with custom rules to block malicious payloads targeting this endpoint.
- Educate administrators about phishing and credential theft risks to prevent unauthorized access.
Description
Emoncms 11.7.3 has a remote code execution vulnerability in the firmware upload feature that allows authenticated users to execute arbitrary commands on the target system. The vulnerability stems from insufficient input validation of user-controlled parameters including filename, port, baud_rate, core, and autoreset within the /admin/upload-custom-firmware endpoint.
