CVE-2024-24892
📋 TL;DR
This vulnerability allows attackers to execute arbitrary operating system commands on systems running vulnerable versions of openEuler migration-tools. It affects systems using migration-tools versions 1.0.0 through 1.0.1 on Linux, potentially leading to full system compromise and privilege escalation.
💻 Affected Systems
- openEuler migration-tools
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with root privileges, data exfiltration, lateral movement within the network, and persistent backdoor installation.
Likely Case
Unauthorized command execution with the privileges of the migration-tools service account, potentially leading to data manipulation, service disruption, or privilege escalation.
If Mitigated
Limited impact if proper network segmentation, least privilege principles, and input validation are implemented, though command injection could still occur within the service context.
🎯 Exploit Status
The vulnerability involves improper input sanitization in a RESTful API endpoint, making exploitation straightforward once the attack vector is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 1.0.1 (check latest release)
Vendor Advisory: https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-1275
Restart Required: Yes
Instructions:
1. Update migration-tools to the latest version from the official openEuler repository. 2. Restart the migration-tools service. 3. Verify the fix by checking the version and testing the affected endpoints.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to the migration-tools RESTful API interface using firewall rules.
sudo iptables -A INPUT -p tcp --dport <migration-tools-port> -s <trusted-ips> -j ACCEPT
sudo iptables -A INPUT -p tcp --dport <migration-tools-port> -j DROP
Service Account Privilege Reduction
linuxRun migration-tools with a non-privileged service account to limit potential damage from command injection.
sudo useradd -r -s /bin/false migrationuser
sudo chown -R migrationuser:migrationuser /path/to/migration-tools
sudo systemctl edit migration-tools.service (set User=migrationuser)
🧯 If You Can't Patch
- Disable or remove migration-tools if not essential for operations.
- Implement strict network segmentation to isolate affected systems from critical assets.
🔍 How to Verify
Check if Vulnerable:
Check the migration-tools version: if it's 1.0.0 or 1.0.1, the system is vulnerable. Review the index.py file for improper input sanitization in command execution functions.Check Version:
Check the package version: rpm -q migration-tools or dpkg -l migration-toolsVerify Fix Applied:
Verify the migration-tools version is updated beyond 1.0.1. Test the RESTful API endpoints with malicious input to ensure command injection is no longer possible.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns in system logs from the migration-tools process
- Failed authentication attempts or unexpected API calls to migration-tools endpoints
Network Indicators:
- Suspicious HTTP requests to migration-tools API endpoints containing shell metacharacters or command injection payloads
SIEM Query:
Example: source="migration-tools.log" AND (command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*")
