CVE-2026-45362 Details
Description
Sangoma Switchvox before 8.4 places cleartext SIP authentication credentials in a backup file.
A vulnerability exists in Sangoma Switchvox versions prior to 8.4, where cleartext SIP authentication credentials are stored in backup files. These `.svb` files, which contain unencrypted carrier authentication details including usernames, passwords, and connection information, can be accessed by any party with possession of the backup. This exposure allows for direct authentication to upstream SIP carriers, potentially leading to impersonation of the PBX endpoint at the carrier level.
Users can update to Sangoma Switchvox version 8.4 or later to address this vulnerability.
