Root code execution via world-writable programs
Published Jun 14, 2024 · Updated Feb 13, 2025
Incorrect permissions in Toshiba Tec e-STUDIO MFPs allow local users to replace executable programs and execute code as root. The Linux firmware marks 106 executable programs mode 777, including 103 root-run binaries, so unprivileged writes replace trusted code. Local access is sufficient; remote exploitation requires a separate file-upload or code-execution path, after which a replaced program runs with its service account privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
