CVE-2025-68462
📋 TL;DR
Freedombox versions before 25.17.1 have improper permissions on the backups-data directory, allowing unauthorized users to read database dump files. This affects all Freedombox installations running vulnerable versions, potentially exposing sensitive database information.

⚠️ Risk & Real-World Impact
Worst Case
Attackers gain access to database dumps containing sensitive user data, credentials, or configuration information, leading to data breaches or credential theft.
Likely Case
Local users or processes with limited access can read database backup files, potentially exposing application data or configuration details.
If Mitigated
With proper directory permissions, only authorized backup processes can access the database dump files, preventing data exposure.
🎯 Exploit Status
Exploitation requires filesystem access to read the directory contents, which typically means local user access or compromised service.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 25.17.1
Vendor Advisory: https://salsa.debian.org/freedombox-team/freedombox/-/commit/8ba444990b4af6eec4b6b2b26482b107d
Restart Required: No
Instructions:
1. Update Freedombox to version 25.17.1 or later using apt. 2. Run: sudo apt update && sudo apt upgrade freedombox. 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Manual directory permission fix
linuxManually set proper permissions on the backups-data directory to restrict access.
sudo chmod 700 /var/lib/freedombox/backups-data
sudo chown freedombox:freedombox /var/lib/freedombox/backups-data
🧯 If You Can't Patch
- Restrict filesystem access to the backups-data directory using appropriate permissions.
- Implement network segmentation to limit which systems can access the Freedombox server.
🔍 How to Verify
Check if Vulnerable:
Check Freedombox version with: dpkg -l | grep freedombox. If version is earlier than 25.17.1, check directory permissions: ls -la /var/lib/freedombox/backups-dataCheck Version:
dpkg -l | grep freedomboxVerify Fix Applied:
Verify Freedombox version is 25.17.1 or later and check directory permissions show restricted access (drwx------).📡 Detection & Monitoring
