• Automated Scripts: Attackers may use automated scripts to repeatedly attempt registration with administrative privileges, increasing the likelihood of successful exploitation.

Exploitation Methods:

• Direct Exploitation: An attacker can directly access the registration form and manipulate the user role selection to gain administrative access.
• Phishing Campaigns: Attackers may use phishing techniques to lure users into registering on a compromised site, thereby gaining administrative access.

3. Affected Systems and Software Versions

Affected Software:

• Service Finder SMS System plugin for WordPress

Affected Versions:

• All versions up to and including 2.0.0

Platform:

6. Technical Details for Security Professionals

Vulnerable Function:

• aonesms_fn_savedata_after_signup()

• Code Review: Conduct a thorough code review of the plugin to identify and rectify the lack of role validation.
• Penetration Testing: Perform penetration testing to simulate the exploitation of this vulnerability and assess the effectiveness of mitigation strategies.

Mitigation Code Example:

function aonesms_fn_savedata_after_signup($user_id) {
    // Ensure the user role is set to a non-administrative role
    $user = get_userdata($user_id);
    if (in_array('administrator', $user->roles)) {
        $user->set_role('subscriber');
    }
}

Conclusion: The CVE-2025-5954 vulnerability in the Service Finder SMS System plugin for WordPress is a critical issue that requires immediate attention.
