CVE-2024-45862
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 · uneditedKastle Systems firmware prior to May 1, 2024, stored machine credentials in cleartext, which may allow an attacker to access sensitive information.
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 confidenceKastle Systems firmware versions prior to May 1, 2024 contain a CWE-312 cleartext storage vulnerability where machine credentials are stored without encryption in the firmware image or associated storage, potentially exposing authentication secrets to attackers who obtain firmware dumps or device 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 installed firmware versionAccess the device admin interface or use the vendor's diagnostic tool to retrieve the current firmware build date or version string. This is typically found under System > About, Device Info, or Firmware Update sections.Affected if The firmware build date is before May 1, 2024, or the version number indicates a release prior to the May 2024 update.
-
Obtain the firmware image fileDownload the firmware binary from the device (via web interface, TFTP, FTP, or USB depending on device model) or locate a previously saved firmware backup. Record the file size and hash for reference.Affected if You successfully obtain the firmware image and it was created or published before May 2024.
-
Extract and inspect firmware contents for credential storageUse binwalk, firmware extraction tools, or the vendor's firmware unpacker to extract the filesystem from the binary. Navigate to directories that typically store credentials such as /etc, /config, /var, or application data folders. Look for files containing usernames, passwords, API keys, tokens, or machine credentials.Affected if Plaintext credentials, passwords, API keys, or authentication tokens are found in any configuration, database, or data files within the extracted firmware filesystem.
-
Check for encryption indicators on credential storageExamine any files suspected of containing credentials for encryption markers. Look for encrypted file headers, key files, or evidence of encryption mechanisms (AES, RSA, or proprietary). Compare the presence and strength of encryption against what the May 2024 update provides.Affected if Credential storage files show no encryption (plaintext), or encryption is absent or weak, indicating credentials are stored without protection.
-
Inspect device local storage if accessibleIf you have physical access or administrative shell access to the device, examine onboard storage (NAND/NOR flash, SD card, or EEPROM) for credential files. Use hex editors or string search tools to identify plaintext secrets stored outside the firmware image.Affected if Credentials are found in plaintext on device storage media, confirming the vulnerability is present in the live system.
The environment is affected if the installed firmware predates May 1, 2024 AND plaintext machine credentials are found within the firmware image or associated storage.

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 · scoped2024-05-01
Update Kastle Systems firmware to the May 2024 or later release which should encrypt credentials at rest. Following the update, rotate all exposed machine credentials as a precautionary measure.
Kastle Systems Access Control System Firmware dated May 1, 2024 or later
- Identify the specific Kastle Systems Access Control System model and current firmware version in use
- Contact Kastle Systems technical support or visit the official vendor website to obtain the firmware update dated May 1, 2024 or later
- Review all release notes and upgrade documentation provided by Kastle Systems
- Backup current system configuration and credentials before proceeding with the upgrade
- Apply the firmware upgrade following the vendor's documented procedure
- After upgrade, verify that credentials are no longer stored in cleartext (confirm encrypted storage)
- Verify normal operation of the access control system post-upgrade
