📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete server takeover, data theft, and deployment of ransomware or backdoors.

🟠

Likely Case

Webshell upload allowing persistent access, data exfiltration, and lateral movement within the network.

🟢

If Mitigated

File upload blocked or sanitized, limiting impact to denial of service or minor data corruption.

🌐 Internet-Facing: HIGH - Attack can be initiated remotely without authentication, making internet-facing instances immediate targets.
🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could exploit this, but requires network access.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploit details are publicly disclosed on GitHub. Requires admin authentication but upload mechanism is trivial to exploit once authenticated.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://www.campcodes.com/

Restart Required: No

Instructions:

No official patch available. Check vendor website for updates. Consider implementing workarounds or replacing software.

🔧 Temporary Workarounds

File Upload Restriction

all

Implement server-side validation to restrict uploaded file types to images only and enforce file extension verification.

# Add to PHP configuration or application code
# Example: Validate file extension and MIME type
$allowed_extensions = ['jpg', 'jpeg', 'png', 'gif'];
$allowed_mime = ['image/jpeg', 'image/png', 'image/gif'];

Access Control Hardening

all

Restrict access to /admin/ directory with IP whitelisting and strong authentication requirements.

# Apache .htaccess example
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
# Or use authentication
AuthType Basic
AuthName "Admin Area"
AuthUserFile /path/to/.htpasswd
Require valid-user

🧯 If You Can't Patch

  • Disable or remove the /admin/edit-subcategory.php file if not required for functionality.
  • Implement web application firewall (WAF) rules to block requests containing suspicious file upload patterns to the vulnerable endpoint.

🔍 How to Verify

Check if Vulnerable:

Attempt to upload a non-image file (e.g., .php, .exe) via the productimage parameters in /admin/edit-subcategory.php. If accepted, system is vulnerable.

Check Version:

Check application version in admin panel or readme files. Default installation is version 1.0.

Verify Fix Applied:

Attempt the same upload test; successful uploads should be rejected with proper validation messages.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file uploads to /admin/edit-subcategory.php
  • Uploads of non-image file types (.php, .exe, .sh)
  • Multiple failed upload attempts followed by successful suspicious upload

Network Indicators:

  • POST requests to /admin/edit-subcategory.php with file uploads
  • Unusual outbound connections from web server following uploads

SIEM Query:

source="web_logs" AND uri="/admin/edit-subcategory.php" AND method="POST" AND (file_extension="php" OR file_extension="exe" OR file_extension="sh")
