CVE-2022-43761
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 · uneditedMissing authentication when creating and managing the B&R APROL database in versions < R 4.2-07 allows reading and changing the system configuration.
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 · moderate confidenceThe vulnerability is a missing authentication mechanism in B&R APROL's database management functionality. Unauthenticated attackers can access the database management interface to read and modify system configuration settings. This affects versions prior to R 4.2-07.

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 installed APROL versionLocate the APROL installation and check the version information, typically found in system information files, control panel entries, or the About section of the APROL management interface. Compare the version number to R 4.2-07.Affected if The installed version is any release prior to R 4.2-07 (e.g., R 4.2-06, R 4.2-05, R 4.1-xx, etc.)
-
Locate database management serviceIdentify the database management component of APROL, which typically handles system configuration storage. Check for services or processes related to database administration or configuration management.Affected if The database management functionality is present and running on the system (this is true for standard APROL installations)
-
Test database management interface accessibilityAttempt to access the database management interface via the typical web-based or service-based endpoint used by APROL for database administration tasks. Observe whether the system prompts for credentials or allows direct access.Affected if The interface is accessible without requiring any authentication credentials (login prompt is absent or bypassed)
-
Assess network exposure of management interfacesReview network configuration to determine if the APROL management ports and interfaces are exposed to untrusted networks or the internet. Check firewall rules and network segmentation configurations.Affected if The database management interface is reachable from untrusted network segments or external IP addresses without proper access controls
You are affected if your APROL installation is version R 4.2-07 or earlier AND the database management interface is accessible without authentication, particularly if exposed to less trusted networks.

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 · scopedUpgrade B&R APROL to version R 4.2-07 or later which includes authentication requirements for database management. If immediate upgrade is not possible, implement network segmentation and restrict access to the APROL management interfaces.
R 4.2-07
- Upgrade B&R APROL to version R 4.2-07 or later to address the missing authentication vulnerability
- Consult B&R Automation documentation for the specific upgrade procedure for your deployment
- After upgrade, verify that authentication is now required for database management operations
- Test that system configuration can only be accessed by authenticated users
