CVE-2022-23377
📋 TL;DR
CVE-2022-23377 is a local file inclusion vulnerability in Archeevo document management systems that allows attackers to read arbitrary files on the server through a crafted file parameter. This affects all Archeevo installations below version 5.0. Attackers can exploit this to access sensitive configuration files and potentially escalate privileges.
💻 Affected Systems
- Archeevo
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through retrieval of sensitive files like /etc/passwd, database credentials, or SSH keys leading to lateral movement and data exfiltration.
Likely Case
Unauthorized access to sensitive configuration files, potentially exposing credentials, system information, or application secrets.
If Mitigated
Limited impact with proper file permissions and network segmentation preventing access to critical system files.
🎯 Exploit Status
Exploit requires simple HTTP requests with crafted file parameter. Multiple public exploits available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.0 and above
Vendor Advisory: https://www.archeevo.com/security-advisories
Restart Required: Yes
Instructions:
1. Backup current installation and data. 2. Download Archeevo version 5.0 or later from official vendor. 3. Follow vendor upgrade documentation. 4. Restart application services. 5. Verify upgrade completed successfully.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation to block file parameter containing path traversal sequences
Modify web.config or application code to sanitize 'file' parameter input
Web Application Firewall Rules
allBlock requests containing path traversal patterns in file parameter
WAF rule: block requests with 'file=~/' or '../' patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Archeevo servers from sensitive systems
- Apply strict file system permissions to limit access to sensitive configuration files
🔍 How to Verify
Check if Vulnerable:
Test by accessing URL: http://target/archeevo/path?file=~/web.config and check if server returns web.config fileCheck Version:
Check Archeevo admin interface or version.txt file in installation directoryVerify Fix Applied:
Attempt same exploit after patching - should return error or sanitized output📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing 'file=~/' in query parameters
- Multiple 200 OK responses to file parameter requests
Network Indicators:
- Unusual file access patterns via web interface
- Requests for known sensitive files like web.config, passwd, shadow
SIEM Query:
source="web_logs" AND (uri_query="*file=~/*" OR uri_query="*file=../*")
