Database-table disclosure via unrestricted diagzip export

Published Feb 16, 2021 · Updated Aug 3, 2024

Information disclosure in Mutare Voice (EVM) 3.2.6 through 3.3.7 allows remote authenticated users to export database tables via diagzip.asp. The administrative utility accepts an arbitrary email address and sends the selected database-table export to that recipient without restricting the destination. Administrative portal access is required, and successful exploitation discloses database contents without modifying data or interrupting service.
