CVE-2024-7701
📋 TL;DR
CVE-2024-7701 is a vulnerability in Percona Toolkit's pt-secure-collect tool that uses weak password hashing algorithms, allowing attackers to perform brute-force attacks against encrypted data. This affects systems using percona-toolkit version 3.6.0 for data collection and encryption. Database administrators and DevOps teams using this tool for sensitive data handling are primarily affected.

Toolkit by Percona
⚠️ Risk & Real-World Impact
Worst Case
Attackers could decrypt sensitive database collection data, potentially exposing credentials, configuration files, or other confidential information stored in encrypted archives.
Likely Case
Unauthorized access to collected diagnostic or backup data containing database metadata, configuration details, or partial data samples.
If Mitigated
Limited exposure of non-sensitive diagnostic information with proper access controls and encryption key management.
🎯 Exploit Status
Exploitation requires obtaining encrypted output files from pt-secure-collect operations.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.6.1 or later
Vendor Advisory: https://www.percona.com/blog/
Restart Required: No
Instructions:
1. Check current version: pt-version
2. Update via package manager: yum update percona-toolkit or apt-get update && apt-get upgrade percona-toolkit
3. Verify update: pt-version should show 3.6.1 or higher
🔧 Temporary Workarounds
Avoid pt-secure-collect encryption
allUse alternative encryption methods or avoid encrypting sensitive data with pt-secure-collect
pt-secure-collect --no-encryption
Use external encryption
linuxCollect data without encryption and encrypt using strong algorithms like AES-256
pt-secure-collect --no-encryption | gpg --symmetric --cipher-algo AES256
🧯 If You Can't Patch
- Avoid using pt-secure-collect for sensitive data collection
- Implement strict access controls on encrypted output files and monitor for unauthorized access
🔍 How to Verify
Check if Vulnerable:
Check if percona-toolkit version is 3.6.0: pt-version | grep 'percona-toolkit'Check Version:
pt-version | grep 'percona-toolkit'Verify Fix Applied:
Verify version is 3.6.1 or higher: pt-version | grep -E 'percona-toolkit.*3\.6\.([1-9]|[1-9][0-9])'📡 Detection & Monitoring
Log Indicators:
- Failed decryption attempts on pt-secure-collect output files
- Unusual access patterns to encrypted archive files
Network Indicators:
- Unexpected transfers of encrypted .tar.gz files from database servers
