Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for unauthenticated POST requests to the ZipFileConfigurationApiHandler endpoint with path parameter set to 'reset_password', which triggers ZIP extraction to /var/cyberx/reset_password without authentication. ↗
- →The vulnerability exploits the password recovery flow: an attacker uploads a crafted ZIP to the reset_password path, then triggers PasswordRecoveryApiHandler via POST. Even if certificate validation fails, the internal Tomcat reset-password endpoint is still called and a new password is generated and returned. Detect unauthenticated POST requests to the password recovery API endpoint. ↗
- →Monitor for unexpected changes to the 'cyberx' or 'support' user passwords on Defender for IoT appliances, which may indicate exploitation of the password recovery bypass. ↗
- ·The decryption key for the product.tar.gz archive is shared across all Defender for IoT installations, meaning any attacker who obtains it can decrypt the source code from any installation. ↗
- ·Both the Management and Sensor components share roughly the same code base, meaning both are affected by the same vulnerabilities including CVE-2021-42310. ↗
- ·The same web interface credentials are also used as SSH login credentials, meaning a successful password reset via this vulnerability also grants SSH access. ↗
- ·The fix requires upgrading to Microsoft Defender for IoT version 10.5.2 or above. ↗
