CVE-2025-61318
📋 TL;DR
Emlog Pro 2.5.20 contains an arbitrary file deletion vulnerability in admin/template.php and admin/plugin.php components. Attackers can exploit directory traversal to delete critical system files without authentication. This affects all Emlog Pro 2.5.20 installations with admin access enabled.
💻 Affected Systems
- Emlog Pro
📦 What is this software?
Emlog by Emlog
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through deletion of critical OS files, web server configuration, or application files leading to denial of service and potential privilege escalation.
Likely Case
Website defacement, data loss, and service disruption by deleting application files, themes, plugins, or configuration files.
If Mitigated
Limited impact if proper file permissions, web application firewalls, and access controls prevent unauthorized admin access.
🎯 Exploit Status
Exploitation requires admin credentials; public proof-of-concept demonstrates directory traversal via deletion parameters.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor Emlog Pro vendor for security updates. 2. Consider upgrading to latest version if available. 3. Apply workarounds immediately.
🔧 Temporary Workarounds
Restrict Admin Access
allLimit admin panel access to trusted IP addresses only.
# Apache: Set in .htaccess
Order deny,allow
Deny from all
Allow from 192.168.1.0/24
# Nginx: Set in nginx.conf
location /admin/ {
allow 192.168.1.0/24;
deny all;
}
File Permission Hardening
linuxSet restrictive permissions on critical directories to prevent deletion.
chmod 755 /var/www/html/emlog
chmod 644 /var/www/html/emlog/*.php
chown www-data:www-data /var/www/html/emlog
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block directory traversal patterns in HTTP requests.
- Disable admin panel entirely if not needed and use read-only configurations.
🔍 How to Verify
Check if Vulnerable:
Check if Emlog Pro version is 2.5.20 by examining the application footer or version.php file.Check Version:
grep -r "2.5.20" /path/to/emlog/ || cat /path/to/emlog/version.phpVerify Fix Applied:
Verify admin/template.php and admin/plugin.php have proper path validation and input sanitization for deletion operations.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to admin/template.php or admin/plugin.php with suspicious parameters containing '../' or similar traversal patterns
- File deletion events in system logs for unexpected files
Network Indicators:
- Unusual POST requests to admin endpoints with file deletion parameters
- Traffic spikes to admin panel from untrusted sources
SIEM Query:
source="web_access.log" AND (uri_path="/admin/template.php" OR uri_path="/admin/plugin.php") AND (query_string="*../*" OR query_string="*delete*")
