Vulnerability Overview
The Backup Migration plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.2.8 via config and log files in the wp-content/backup-migration/ folder. This can allow unauthenticated attackers to extract sensitive data in certain configurations, including the site administrator's email address and the locations of site backups as well as the backups themselves.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-538: Insertion of Sensitive Information into Externally-Accessible File or Directory
The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information.
Remediation
Update to version 1.2.9, or a newer patched version
How does WordSec protect against this?
