CVE-2022-25577
📋 TL;DR
ALF-BanCO v8.2.5 and earlier uses a hardcoded password to encrypt its SQLite database, allowing attackers with system access to read and modify user data. This affects all installations using vulnerable versions, potentially exposing sensitive financial or personal information.

📦 What is this software?
Alf Banco by Alf Banco
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all database contents including financial transactions, user credentials, and sensitive personal data, leading to data theft, fraud, or system manipulation.
Likely Case
Unauthorized access to database contents by attackers with system access, resulting in data exposure and potential integrity violations.
If Mitigated
Limited impact if database is isolated with strict access controls, though hardcoded credentials remain a persistent risk.
🎯 Exploit Status
Exploitation requires system access but is trivial once access is obtained. Public proof-of-concept demonstrates database decryption.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Upgrade to a version above 8.2.5 if released by vendor, or implement workarounds.
🔧 Temporary Workarounds
Database Re-encryption
allExport database contents and re-encrypt with a strong, unique password not embedded in code.
sqlite3 database.db .dump > backup.sql
# Re-import with encryption using a secure method
Application Isolation
linuxRun ALF-BanCO in a restricted environment with minimal access to database files.
# Use containerization or VM with limited permissions
# chmod 600 database.db
# Set up proper file system ACLs
🧯 If You Can't Patch
- Implement strict access controls to limit who can access the system running ALF-BanCO.
- Monitor database file access and alert on unauthorized attempts to read or modify the SQLite database.
🔍 How to Verify
Check if Vulnerable:
Check ALF-BanCO version. If version is 8.2.5 or lower, it is vulnerable. Examine application binaries for hardcoded encryption strings.Check Version:
Check application interface or documentation for version information. On Linux: strings application_binary | grep -i versionVerify Fix Applied:
Verify database encryption uses a unique, non-hardcoded password. Test that the hardcoded password no longer decrypts the database.📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to database files
- Failed decryption attempts with hardcoded password
- Unexpected SQLite read/write operations
Network Indicators:
- Not applicable - this is a local file system vulnerability
