CVE-2024-7315
📋 TL;DR
The Migration, Backup, Staging WordPress plugin before version 0.9.106 uses insufficient randomness when generating backup filenames, allowing attackers to brute-force guess these filenames and potentially access sensitive backup data. This affects WordPress sites using vulnerable versions of this plugin. Attackers could discover and download backups containing database credentials, user data, or other sensitive information.
💻 Affected Systems
- Migration, Backup, Staging WordPress plugin
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers download full site backups containing database credentials, admin passwords, user PII, and configuration files, leading to complete site compromise and data breach.
Likely Case
Attackers discover and download recent backups containing sensitive data like database dumps, configuration files, or user information.
If Mitigated
Attackers cannot guess backup filenames due to proper randomness, preventing unauthorized access to backup files.
🎯 Exploit Status
Exploitation requires brute-forcing predictable backup filenames. No authentication needed if backups are accessible via web.
