CVE-2022-43989
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 · uneditedPassword recovery vulnerability in SICK SIM2x00 (ARM) Partnumber 1092673 and 1081902 with firmware version < 1.2.0 allows an unprivileged remote attacker to gain access to the userlevel defined as RecoverableUserLevel by invocating the password recovery mechanism method. This leads to an increase in their privileges on the system and thereby affecting the confidentiality integrity and availability of the system. An attacker can expect repeatable success by exploiting the vulnerability. The recommended solution is to update the firmware to a version >= 1.2.0 as soon as possible (available in SICK Support Portal).
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 confidencePassword recovery vulnerability in SICK SIM2x00 industrial controllers allows unprivileged remote attackers to invoke the password recovery mechanism to gain access to the RecoverableUserLevel, resulting in privilege escalation. This affects firmware versions prior to 1.2.0 on part numbers 1092673 and 1081902.

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 device modelLocate the SICK industrial controller on the network or physically inspect the hardware labeling to confirm it is a SIM2000 or SIM2500 modelAffected if The device is not a SICK SIM2000 or SIM2500 controller, then it is not affected by this CVE
-
Check the firmware versionAccess the device's web interface, management console, or use the manufacturer's diagnostic tool to retrieve the installed firmware versionAffected if The firmware version is less than 1.2.0, indicating the device is vulnerable
-
Verify the part numberCheck the hardware label or system information to identify the part number - look for 1092673 (Sim2000) or 1081902 (Sim2500)Affected if The part number matches 1092673 or 1081902 and the firmware is below 1.2.0, the device is affected
-
Assess password recovery accessibilityDetermine if the password recovery mechanism is exposed and accessible to unprivileged users on the network interfaceAffected if The password recovery feature can be invoked without administrator privileges, confirming the vulnerability is exploitable
A SICK SIM2000 or SIM2500 controller with part number 1092673 or 1081902 running firmware version below 1.2.0 with an accessible password recovery mechanism is affected by this vulnerability.

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 · scoped1.2.0
Update firmware to version >= 1.2.0 (available from SICK Support Portal) to remediate the vulnerability.
Firmware >= 1.2.0
- Identify the exact model number and current firmware version of the SICK SIM2000 or SIM2500 device
- Download the firmware version 1.2.0 or later from the SICK Support Portal (sick.com)
- Review the SICK firmware upgrade documentation for your specific device model
- Ensure the device is powered on and connected to a stable network before initiating the upgrade
- Access the device management interface (web-based or through SICK configuration software)
- Navigate to the firmware update section and upload the new firmware file
- Initiate the firmware upgrade process and wait for completion - do not power off the device during this process
- After upgrade completes, verify the new firmware version is 1.2.0 or later
