CVE-2023-2315
📋 TL;DR
This path traversal vulnerability in OpenCart allows authenticated users with Log component modify privileges to delete arbitrary files on the server. It affects OpenCart installations from version 4.0.0.0 through 4.0.2.2. Attackers could potentially delete critical system files or application data.
💻 Affected Systems
- OpenCart
📦 What is this software?
Opencart by Opencart
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via deletion of critical system files, leading to service disruption, data loss, or privilege escalation.
Likely Case
Unauthorized deletion of application files, configuration files, or user data causing service disruption and data loss.
If Mitigated
Limited impact if proper access controls and file permissions are in place, restricting damage to non-critical files.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained. Public proof-of-concept available in advisory links.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.0.2.3 and later
Vendor Advisory: https://github.com/opencart/opencart/commit/0a8dd91e385f70e42795380009fd644224c1bc97
Restart Required: No
Instructions:
1. Backup your OpenCart installation and database. 2. Download OpenCart 4.0.2.3 or later from official sources. 3. Replace affected files with patched versions. 4. Clear OpenCart cache. 5. Verify functionality.
🔧 Temporary Workarounds
Restrict Log Component Access
allRemove modify privileges from Log component for non-essential users
Navigate to System > Users > User Groups in OpenCart admin panel
Edit user groups to remove 'access/modify' permission for Log component
File Permission Hardening
linuxSet restrictive permissions on critical directories to prevent deletion
chmod 755 /path/to/opencart/
chmod 644 /path/to/opencart/system/storage/logs/*
chmod 755 /path/to/opencart/system/storage/logs/
🧯 If You Can't Patch
- Implement strict access controls: Only grant Log component modify privileges to absolutely necessary administrative accounts.
- Enable comprehensive logging and monitoring of file deletion activities, particularly in system directories.
🔍 How to Verify
Check if Vulnerable:
Check OpenCart version in admin panel Dashboard or examine /upload/version.php file for version string.Check Version:
grep -r "define.*VERSION" /path/to/opencart/upload/version.phpVerify Fix Applied:
Verify version is 4.0.2.3 or later, and check that the patch commit 0a8dd91e385f70e42795380009fd644224c1bc97 is applied in the codebase.📡 Detection & Monitoring
Log Indicators:
- Unusual file deletion events in system logs
- Multiple failed authentication attempts followed by successful login and file operations
- Admin panel access from unusual IP addresses
Network Indicators:
- HTTP POST requests to admin log endpoints with suspicious file paths
- Unusual outbound traffic patterns after file deletion
SIEM Query:
source="opencart_logs" AND (event="file_deletion" OR event="log_clear") AND file_path CONTAINS "../"
