CVE-2026-22911
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 · uneditedFirmware update files may expose password hashes for system accounts, which could allow a remote attacker to recover credentials and gain unauthorized access to the device.
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 confidenceThis vulnerability exists in the firmware update mechanism where password hashes for system accounts are exposed within the firmware update files themselves. A remote attacker who obtains these firmware files (which may be publicly available through vendor download sites or intercepted during transit) can extract the password hashes and potentially crack them to recover plaintext credentials. This grants unauthorized access to the device's system accounts.

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.
-
Confirm presence of Sick Tdc X401gl deviceInventory your network or device assets to identify if any Sick Tdc X401gl devices are deployed in your environmentAffected if The device model matches the affected product
-
Locate firmware update filesSearch for firmware update files for the Sick Tdc X401gl in your environment - check vendor download areas, update servers, local storage, or documentation repositoriesAffected if Firmware update files for this device exist in your environment
-
Extract firmware contentsUse firmware extraction tools (binwalk, firmware-mod-kit, or similar) to unpack the firmware binary and examine its contentsAffected if You are able to extract and inspect the firmware file system contents
-
Search for password hash patternsWithin the extracted firmware, search for hash patterns typical of /etc/shadow files, salted password hashes, or credential storage formats (look for $id$salt$hash patterns, or hex strings resembling MD5/SHA hashes)Affected if The firmware contains recognizable password hash strings or credential files
-
Check firmware file accessibilityReview whether firmware files are stored in locations with weak access controls, are downloadable from public vendor sites without authentication, or could be intercepted during distributionAffected if Firmware files are accessible to unauthorized parties or publicly available
You are affected if you use Sick Tdc X401gl devices and their firmware files (whether stored internally or obtained from vendor sites) contain password hashes that could be extracted and cracked by an attacker who obtains the firmware.

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 dataImplement proper access controls and encryption on firmware update files; ensure password hashes are not stored in firmware or use salted, iterated hashing with appropriate key derivation functions if credential storage in firmware is necessary.
