Unauthenticated user-data disclosure via invalid_browser error path

Published Feb 14, 2022 · Updated Aug 4, 2024

Information disclosure in Sangoma Switchvox 102409 allows remote attackers to read user data via an unauthenticated HTTP GET request. The /main?cmd=invalid_browser error path returns an HTTP 200 page whose gJSON variable embeds account, extension, server, and profile data. No credentials or user interaction are required, and the demonstrated consequence is disclosure of PBX user and system metadata.
