CVE-2023-40582
📋 TL;DR
CVE-2023-40582 is a command injection vulnerability in find-exec utility versions before 1.0.3 that allows attackers to execute arbitrary shell commands by controlling input parameters. This affects all users of vulnerable find-exec versions who process untrusted input. Attackers can achieve remote code execution with the privileges of the running process.
💻 Affected Systems
- find-exec
📦 What is this software?
Find Exec by Find Exec Project
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via remote code execution, allowing attackers to install malware, exfiltrate data, or pivot to other systems.
Likely Case
Local privilege escalation or execution of arbitrary commands in the context of the vulnerable application.
If Mitigated
No impact if input validation and proper escaping are implemented, or if only trusted input is processed.
🎯 Exploit Status
Command injection vulnerabilities are typically easy to exploit. The advisory provides technical details but no public exploit code.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.0.3
Vendor Advisory: https://github.com/shime/find-exec/security/advisories/GHSA-95rp-6gqp-6622
Restart Required: No
Instructions:
1. Update find-exec: npm update find-exec -g 2. Verify version: find-exec --version 3. Ensure version is 1.0.3 or higher
🔧 Temporary Workarounds
Input validation and sanitization
allImplement strict input validation to only allow expected characters and sanitize all user input before passing to find-exec.
# Example: Validate input contains only alphanumeric characters
if [[ ! "$input" =~ ^[a-zA-Z0-9]+$ ]]; then
echo "Invalid input"
exit 1
fi
🧯 If You Can't Patch
- Restrict find-exec usage to only process input from trusted, validated sources
- Implement network segmentation and access controls to limit who can interact with vulnerable systems
🔍 How to Verify
Check if Vulnerable:
Check find-exec version: find-exec --version. If version is below 1.0.3, system is vulnerable.Check Version:
find-exec --versionVerify Fix Applied:
After updating, verify version is 1.0.3 or higher: find-exec --version📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns
- Suspicious shell commands in find-exec process logs
- Multiple failed parameter validation attempts
Network Indicators:
- Unexpected outbound connections from find-exec processes
- Command and control traffic patterns
