Overview<\/strong><\/p>\n

The CVE-2025-3054 vulnerability is a critical security flaw found in the WP User Frontend Pro plugin for WordPress. This flaw allows authenticated attackers with subscriber-level access or above to upload arbitrary files to the affected site’s server. The vulnerability arises due<\/a> to a lack of file type validation in the upload_files() function, thus potentially enabling remote code execution. It is crucial for all WordPress sites using this plugin<\/a>, particularly those that have the ‘Private Message’ module enabled and are using the Business version of the PRO software, to take immediate action and secure their systems.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-3054
\nSeverity: High (8.8 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low (Subscriber-level access)
\nUser Interaction: Required
\nImpact: Potential system compromise or data<\/a> leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

WP User Frontend Pro<\/a> Plugin for WordPress | Up to and including 4.1.3<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability is based on the lack of file<\/a> type validation in the upload_files() function within the WP User Frontend Pro plugin. An attacker with subscriber-level access can misuse this function to upload arbitrary files<\/a>, including those having malicious content. Once uploaded, these files could be executed on the server, leading to potential remote code execution and system<\/a> compromise. It is important to note that this exploit requires the ‘Private Message’ module to be enabled.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how an attacker might exploit<\/a> this vulnerability:<\/p>\n

POST \/wp-user-frontend-pro\/upload_files HTTP\/1.1\nHost: target-wordpress-site.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"malicious_script.php\"\nContent-Type: application\/x-php\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this example, the attacker sends a HTTP POST request to the vulnerable endpoint with a malicious PHP script<\/a> as a file upload. If successful, this script could enable the attacker to execute arbitrary<\/a> commands on the server.<\/p>\n
Remediation<\/strong><\/p>\n
To mitigate this vulnerability, it is strongly recommended to apply the vendor patch once it is available. Until then, using a web application firewall (WAF) or intrusion detection system (IDS) can aid in detecting and preventing potential attacks<\/a>. Additionally, disable the ‘Private Message’ module if it is not in use. Regularly updating all plugins and monitoring for suspicious activity can further enhance security<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
