CVE-2023-25805
📋 TL;DR
CVE-2023-25805 is a command injection vulnerability in versionn software that allows attackers to execute arbitrary commands on the system. All users running versionn versions prior to 1.1.0 are affected. The vulnerability stems from improper neutralization of special elements used in OS commands.
💻 Affected Systems
- versionn
📦 What is this software?
Versionn by Versionn Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution, data theft, and lateral movement across the network.
Likely Case
Unauthorized command execution leading to data exfiltration, system modification, or service disruption.
If Mitigated
Limited impact with proper input validation and command sanitization in place.
🎯 Exploit Status
Command injection vulnerabilities typically have low exploitation complexity when user-controlled input reaches vulnerable functions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.1.0
Vendor Advisory: https://github.com/commenthol/versionn/security/advisories/GHSA-fj78-2vc5-f6cm
Restart Required: No
Instructions:
1. Update versionn to version 1.1.0 or later using your package manager. 2. Verify the update completed successfully. 3. Test versionn functionality to ensure compatibility.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitize all user-controlled inputs before passing to versionn commands.
Restrict Versionn Usage
allLimit versionn usage to trusted users and environments only.
🧯 If You Can't Patch
- Remove versionn from production systems if not essential
- Implement network segmentation to isolate systems running vulnerable versionn
🔍 How to Verify
Check if Vulnerable:
Check versionn version using 'versionn --version' or check package manager. If version is below 1.1.0, system is vulnerable.Check Version:
versionn --versionVerify Fix Applied:
After updating, run 'versionn --version' to confirm version is 1.1.0 or higher.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns
- Suspicious process creation from versionn
- Error logs showing command injection attempts
Network Indicators:
- Unexpected outbound connections from systems running versionn
SIEM Query:
Process creation where parent process contains 'versionn' and command line contains suspicious characters like ;, |, &, $, (, )🔗 References
