CVE-2024-32676: Improper Restriction of Excessive Authentication Attempts Vulnerability in LoginPress LoginPress Pro and How it Leads to the Removal of Important Client Functionality

A recently discovered vulnerability, identified as CVE-2024-32676, is wreaking havoc on web applications that use LoginPress LoginPress Pro. This vulnerability affects all the versions of LoginPress Pro before 3... The vulnerability of Improper Restriction of Excessive Authentication Attempts issues allows the removal of important client functionalities. Let's dive deep into the details of this vulnerability, including what it is, how it exploits the affected systems, and the code snippet that showcases the vulnerability, as well as the links to the original references documenting this vulnerability.

CVE-2024-32676 Explained

CVE-2024-32676 is a vulnerability present in the LoginPress LoginPress Pro plugin that does not properly restrict excessive authentication attempts. In simple terms, an attacker can exploit this vulnerability to remove essential client functionalities from the application through repeated authentication attempts.

This issue occurs when the LoginPress LoginPress Pro plugin doesn't limit the number of failed login attempts, thus allowing an attacker to submit an unlimited number of login requests. Once the attacker gains unauthorized access, they can remove or modify critical client functionalities in the application. Consequently, this may lead to unauthorized data access, deleted data, or other unintended consequences within the application.

Code Snippet

To better understand the vulnerability, let's examine a simple code snippet that showcases the lack of proper restrictions on authentication attempts in LoginPress LoginPress Pro:

function check_authentication($username, $password) {
    $authenticated = false;
  
    if (validate_credentials($username, $password)) {
        $authenticated = true;
    }
    
    return $authenticated;
}

In this particular function, there are no restrictions on the number of attempts for supplying the username and password. Essentially, an attacker can perform a brute force attack to try and successfully log into the application through countless attempts, which should never be possible if proper security measures and restrictions are in place.
