CVE-2019-25253Public exploitNetwork attack vector

Unauthenticated file disclosure via external DTD entities

Published Dec 24, 2025 · Updated Dec 24, 2025

XXE in KYOCERA Net Admin 3.4.0906 allows remote attackers to read arbitrary Windows files through a crafted Multi-Set template. The kmmted.exe editor, invoked by MultisetTemplateEditorActiveXComponent.dll, parses external DTD parameter entities without sanitizing the XML input. Exploitation requires the template to be processed and sends file contents to an attacker-controlled server through out-of-band HTTP requests.
