CVE-2024-27159
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 · uneditedAll the Toshiba printers contain a shell script using the same hardcoded key to encrypt logs. An attacker can decrypt the encrypted files using the hardcoded key. This vulnerability can be executed in combination with other vulnerabilities and difficult to execute alone. So, the CVSS score for this vulnerability alone is lower than the score listed in the "Base Score" of this vulnerability.

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 confidenceToshiba printers contain a shell script that uses a hardcoded encryption key for log files. The same key is used across all affected devices, allowing an attacker who obtains the key to decrypt any encrypted log files. This vulnerability is difficult to exploit in isolation and requires chaining with other vulnerabilities.

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 Toshiba printer models in your environmentReview your asset inventory or network scan results for Toshiba printer devices. Check device web interfaces or print server configurations for Toshiba logo/branding and model numbers.Affected if Any identified printer is a Toshiba device (regardless of specific model number, since version ranges are not specified)
-
Locate the log encryption shell scriptAccess the printer's internal file system via FTP, SMB, or the web administrative interface file browser. Look for shell scripts in /etc/, /usr/local/, or similar directories that handle log encryption or rotation.Affected if A shell script exists that performs encryption of log files using a shared/hardcoded key
-
Verify the hardcoded key presenceExamine the shell script content for a static encryption key string. Search the script file for cryptographic key variables, base64-encoded strings, or hardcoded password/secret patterns.Affected if The script contains a hardcoded encryption key rather than a unique, device-specific key
-
Confirm log encryption is enabledCheck the printer's administrative settings, configuration files, or the shell script execution logs to determine if log encryption is currently active or scheduled to run.Affected if Log encryption is enabled or has been run on the device, meaning encrypted logs exist that could be decrypted with the obtained key
If you have any Toshiba printer where a shell script uses a hardcoded encryption key for log files and log encryption is active, your environment is potentially affected by this CVE.

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 dataContact Toshiba for firmware updates that address the hardcoded key issue; until then, isolate affected printers on restricted network segments and monitor for unauthorized access attempts.
