CVE-2024-27167
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 · uneditedToshiba printers use Sendmail to send emails to recipients. Sendmail is used with several insecure directories. A local attacker can inject a malicious Sendmail configuration file. As for the affected products/models/versions, see the reference URL.
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 in Toshiba printers allows a local attacker to inject a malicious Sendmail configuration file due to insecure directory permissions. The Sendmail service is configured to use directories with improper access controls, enabling a local user to replace or modify configuration files and potentially escalate privileges or manipulate email routing.

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 device is a Toshiba printer with Sendmail serviceAccess the printer's web administrative interface or check the device model documentation to verify the manufacturer is Toshiba and identify if Sendmail is listed as an available service in the configuration or status pagesAffected if The device is a Toshiba printer that supports or includes Sendmail functionality for email forwarding or alerting
-
Locate Sendmail configuration directoriesNavigate to the printer's administrative settings and locate paths related to email, SMTP, or Sendmail configuration. Common paths may include /etc/mail, /var/spool/mail, or similar configuration directories accessible via the printer's file system or web UIAffected if Sendmail configuration directories exist on the device and are accessible to local users
-
Check directory permissions on Sendmail config locationsUse the printer's diagnostic or file management interface to view the permission settings (mode bits) on the identified Sendmail configuration directories. Look for directories with permissions such as 777, 775, or any setting that allows write access by non-privileged users (world-writable or group-writable)Affected if Any Sendmail configuration directory shows world-writable (o+w) or group-writable (g+w) permissions, or permissions like 777 or 775
-
Verify ownership of configuration filesInspect the ownership settings of Sendmail configuration files (such as sendmail.cf, submit.cf, or alias files) within the configuration directories. Check if files are owned by a non-root user or if ownership allows modification by low-privilege accountsAffected if Configuration files are owned by a user other than root or system administrator, or ownership is set to a privileged group that includes non-admin accounts
-
Test for local user write accessIf the printer allows shell or limited command access, attempt to create or modify a test file in the Sendmail configuration directory using a low-privilege account. Alternatively, review access control lists or permission inheritance settings that may grant write access to local usersAffected if A local non-administrative user can successfully write or modify files in Sendmail configuration directories
A user is affected if they have a Toshiba printer with Sendmail enabled and the Sendmail configuration directories have world-writable or group-writable permissions that allow non-root users to modify configuration files.

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 dataSecure Sendmail configuration directories by removing world/group writable permissions, ensure configuration files are owned by root with restrictive permissions, and consider updating to patched firmware versions if available from Toshiba.
