CVE-2025-9487

4.7 MEDIUM

📋 TL;DR

The Admin and Site Enhancements (ASE) WordPress plugin before version 7.9.8 fails to properly sanitize SVG files uploaded via xmlrpc.php when uploads are enabled. This allows authenticated users to upload malicious SVG files containing cross-site scripting (XSS) payloads, potentially compromising site visitors. WordPress sites using vulnerable ASE plugin versions with xmlrpc.php enabled are affected.

💻 Affected Systems

Products:
  • Admin and Site Enhancements (ASE) WordPress plugin
Versions: All versions before 7.9.8
Operating Systems: Any OS running WordPress
Default Config Vulnerable: ✅ No
Notes: Requires xmlrpc.php uploads to be enabled (not default in many configurations) and authenticated user access to upload files.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker uploads a malicious SVG file that executes JavaScript payloads in visitors' browsers, potentially stealing session cookies, redirecting users to malicious sites, or performing actions on behalf of authenticated users.

🟠

Likely Case

Authenticated users with upload privileges (like authors or editors) could upload malicious SVG files that execute JavaScript when viewed by administrators or other users, potentially leading to privilege escalation or account takeover.

🟢

If Mitigated

With proper controls like disabling xmlrpc.php or restricting SVG uploads, the attack surface is significantly reduced, though the core vulnerability remains in the plugin code.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: LOW

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires authenticated access to upload files via xmlrpc.php, which may be disabled by default in many WordPress configurations.

Disable xmlrpc.php entirely

all

Completely disable xmlrpc.php if not needed

Add to .htaccess: <Files xmlrpc.php> Order Deny,Allow Deny from all </Files>
Or use security plugin to disable XML-RPC

🧯 If You Can't Patch

  • Disable the ASE plugin temporarily until patched
  • Implement web application firewall rules to block malicious SVG upload patterns

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel > Plugins > Installed Plugins for ASE plugin version. If version is below 7.9.8, system is vulnerable.

Check Version:

wp plugin list --name='Admin and Site Enhancements' --field=version (if WP-CLI installed)

Verify Fix Applied:

Confirm ASE plugin version is 7.9.8 or higher in WordPress admin panel.

📡 Detection & Monitoring

Log Indicators:

  • Multiple SVG file uploads via xmlrpc.php endpoint
  • Unusual file upload patterns from authenticated users
  • POST requests to /xmlrpc.php with file upload parameters

Network Indicators:

  • XML-RPC requests containing SVG file uploads
  • Unusual traffic to xmlrpc.php endpoint

SIEM Query:

source="wordpress.log" AND (uri_path="/xmlrpc.php" AND method="POST" AND (file_extension="svg" OR content_type="image/svg+xml"))
