CVE-2024-27142Public exploitNetwork attack vector

Device stoppage via unauthenticated recursive entity expansion

Published Jun 14, 2024 · Updated Feb 13, 2025

XXE in the e-STUDIO /contentwebserver API allows remote attackers to stop affected Toshiba Tec MFPs with unauthenticated HTTP requests. The mod_contentwebserver.so parser expands attacker-controlled recursive DTD entities, and deeply nested expansion sharply increases request processing time. Network access to the API is sufficient; the disclosure also reports information retrieval but did not analyze that impact in depth.
