CVE-2022-27582
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 SIM4000 (PPC) Partnumber 1078787 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 firmware versions <=1.10.1 allow to optionally disable device configuration over the network interfaces. Please make sure that you apply general security practices when operating the SIM4000. A fix is planned but not yet scheduled.
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 confidencePassword recovery vulnerability in SICK SIM4000 industrial controllers allows an unprivileged remote attacker to obtain elevated 'RecoverableUserLevel' access by invoking the password recovery mechanism. This provides a direct authentication bypass enabling privilege escalation with critical impact to confidentiality, integrity, and availability.

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 SICK SIM device modelQuery the device's system information or check the device nameplate/labels to determine if it is a Sim2000, Sim2000st, Sim2500, Sim1012, Sim1004, Sim1000 Fx, or Sim4000 controllerAffected if The device is any of these seven models
-
Determine the installed firmware versionAccess the device's web interface, system settings, or use the vendor's diagnostic tool to retrieve the current firmware versionAffected if The firmware version is below 1.2.0 for Sim2000/Sim2000st/Sim2500, below 2.2.0 for Sim1012, below 2.0.0 for Sim1004, below 1.6.0 for Sim1000 Fx, or any version for Sim4000
-
Verify network exposure of the password recovery interfaceCheck the device's network configuration settings to determine if the password recovery or configuration interface is accessible over network interfaces (HTTP/HTTPS/remote access ports)Affected if The device allows remote network access to its password recovery mechanism without requiring privileged authentication
-
Confirm if RecoverableUserLevel is enabledInspect the user authentication settings or user level configuration within the device's administrative interface to see if the RecoverableUserLevel feature is activeAffected if The RecoverableUserLevel feature is enabled and accessible to unprivileged users
The environment is affected if a SICK SIM controller model matches the affected product list AND the installed firmware version falls within the vulnerable ranges (or is any version for Sim4000) AND the password recovery interface is network-accessible.

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.
From vendor data1.2.01.6.02.0.0
Where firmware supports it, disable device configuration over network interfaces; otherwise implement strict network segmentation and firewall controls to limit remote access to trusted personnel only.
