CVE-2022-4333
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHardcoded Credentials in multiple SPRECON-E CPU variants of Sprecher Automation allows an remote attacker to take over the device. These accounts should be deactivated according to Sprecher's hardening guidelines.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceHardcoded authentication backdoor in multiple SPRECON-E CPU variants from Sprecher Automation allows remote unauthenticated attackers to gain full device control. The embedded credentials bypass normal authentication mechanisms and provide administrative access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Sprecon device modelLog into the device web interface or check the device label/hardware documentation to confirm the exact model variant (e.g., Sprecon E P Dq6 1, Sprecon E C, etc.)Affected if The device model matches any of the affected variants listed in the CVE (P Dq6 1, P Dl6 1, P Ds6 0, C, T3, Tc Ax 3110, Ap 2200, Cp 2131)
-
Confirm the firmware versionAccess the device management interface and locate the firmware version information, typically found under System Info, Device Status, or About sectionsAffected if The device is running any firmware version of the affected Sprecon E variants (all versions are affected)
-
Review device user accounts for unauthorized entriesAccess the user management or account configuration panel in the device web interface and enumerate all defined user accountsAffected if Unexpected or undocumented accounts exist beyond those created by legitimate administrators, especially accounts with administrative privileges
-
Inspect authentication configuration filesIf accessible via FTP, SSH, or SD card export, examine configuration backups or user database files for embedded credentials or additional accounts not created through the normal admin interfaceAffected if Configuration files contain hardcoded username/password pairs that are not documented in the device administration manual
-
Check for abnormal administrative sessionsReview device logs or session records for administrative logins from IP addresses or times not initiated by your organizationAffected if Administrative sessions are recorded from unknown sources or at unusual times indicating unauthorized access via the backdoor
If the device is any Sprecon E variant listed in the CVE with any firmware version and contains undocumented administrative accounts or shows evidence of unauthorized access, the environment is affected by this hardcoded backdoor vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedLocate and deactivate the hardcoded accounts on affected devices per Sprecher's hardening guidelines immediately. Implement network segmentation to reduce exposure until remediation can be safely executed.
- 1. Identify the hardcoded accounts present on the Sprecon-E device by reviewing the device documentation or contacting Sprecher Automation support.
- 2. Access the device management interface using administrator credentials.
- 3. Navigate to the user account management section.
- 4. Locate and deactivate any hardcoded accounts mentioned in the vulnerability disclosure.
- 5. Create new, unique user accounts with strong, unique passwords following Sprecher's hardening guidelines.
- 6. Verify that the hardcoded accounts are no longer accessible by attempting to log in with the known credentials.
- 7. Document the changes and monitor for any unauthorized access attempts.
