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

In the rapidly evolving digital landscape, cyber threats have become a substantial concern for many organizations. One of the latest vulnerabilities discovered is CVE-2025-1304, which affects the NewsBlogger theme for WordPress, a popular CMS (Content Management System). The vulnerability lies within the newsblogger_install_and_activate_plugin() function, which lacks a necessary capability check, leading to potential unauthorized file<\/a> uploads.
\nThis vulnerability matters because it gives attackers with subscriber-level access the potential to upload arbitrary files<\/a> onto the affected site’s server. In a worst-case scenario, this could result in remote code<\/a> execution, compromising the entire system or leading to substantial data leakage.<\/p>\n

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

CVE ID: CVE-2025-1304
\nSeverity: High (8.8)
\nAttack Vector: Network
\nPrivileges Required: Low (Subscriber-level access)
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

NewsBlogger Theme for WordPress<\/a> | Up to and including 0.2.5.1<\/p>\n

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

The exploit takes advantage of a missing capability check in the newsblogger_install_and_activate_plugin() function. This function, present in the NewsBlogger WordPress Theme, fails to properly verify the user’s privileges<\/a> when uploading a file. As a result, even a user with minimal privileges, such as a subscriber, can upload arbitrary files<\/a> onto the server.
\nThis vulnerability opens the door for a potential remote code<\/a> execution attack. If an attacker uploads a malicious file and is able to execute it, they could potentially gain control of the server, leading to system<\/a> compromise or significant data leakage.<\/p>\n

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

The following is a conceptual example of how an attacker might exploit this vulnerability<\/a> by sending an HTTP POST request with a malicious file:<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=newsblogger_upload_file HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"malicious.php\"\nContent-Type: application\/x-php\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this example, a PHP file that contains a command execution<\/a> function is uploaded. If the server processes this file, it could lead to remote code execution<\/a>, compromising the system.<\/p>\n","protected":false},"excerpt":{"rendered":"
