CVE-2024-27168Public exploitNetwork attack vector

Administrative API access via hardcoded cookie-signing keys

Published Jun 14, 2024 · Updated Feb 13, 2025

Authentication bypass in Toshiba Tec e-STUDIO MFPs allows remote attackers to access administrative APIs by forging session cookies. The Settingapp, HomeApp, and WebServerApp Pyramid WSGI configurations reuse embedded session.secret values to sign authentication cookies. Apache exposes these applications through a reverse proxy, so network access to the MFP and knowledge of the disclosed keys are sufficient to reach administrative interfaces and read protected information.
