⚠️ Risk & Real-World Impact

🔴

Worst Case

Full server compromise through local file inclusion leading to remote code execution, sensitive file access (like /etc/passwd, configuration files), and complete system takeover.

🟠

Likely Case

Sensitive information disclosure (database credentials, configuration files), limited file system access, and potential privilege escalation through included PHP files.

🟢

If Mitigated

Limited impact with proper file permissions, web server sandboxing, and disabled dangerous PHP functions like allow_url_include.

🌐 Internet-Facing: HIGH - WordPress themes are typically internet-facing, and this vulnerability can be exploited remotely without authentication.
🏢 Internal Only: MEDIUM - Internal systems could still be vulnerable to internal attackers or compromised accounts.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Simple HTTP requests can trigger the vulnerability; exploit tools for PHP LFI are widely available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version after 1.5 (check vendor for specific fixed version)

🔧 Temporary Workarounds

Disable vulnerable theme

all

Temporarily disable Caliris theme and switch to default WordPress theme

wp theme deactivate caliris
wp theme activate twentytwentyfour

PHP configuration hardening

linux

Disable dangerous PHP functions and restrict file inclusion

Add to php.ini: allow_url_include = Off
Add to php.ini: open_basedir = /var/www/html

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to block LFI patterns
  • Restrict file system permissions and implement strict access controls

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel > Appearance > Themes for Caliris version 1.5 or earlier

Check Version:

wp theme list --field=name,status,version | grep caliris

Verify Fix Applied:

Verify Caliris theme is either updated to version after 1.5 or completely removed from themes directory

📡 Detection & Monitoring

Log Indicators:

  • Unusual include/require statements in PHP error logs
  • HTTP requests with file path traversal patterns (../, /etc/passwd)

Network Indicators:

  • HTTP requests containing file inclusion parameters with path traversal

SIEM Query:

web_access_logs WHERE url CONTAINS 'include=' OR url CONTAINS 'require=' AND (url CONTAINS '../' OR url CONTAINS '/etc/' OR url CONTAINS 'php://')
