Akinsoft ProKuafor | s1.02.08 before v1.02.08

How the Exploit Works

This vulnerability stems from an improper restriction of excessive authentication attempts in Akinsoft ProKuafor. An attacker can exploit this flaw by making repeated authentication attempts, eventually bypassing the system’s authentication mechanism. This could result in unauthorized access to the system, potentially leading to system compromise or data leakage.

Conceptual Example Code

An attacker could leverage this vulnerability by repetitively sending POST requests to the authentication endpoint. The conceptual code below illustrates how such an attack might occur:

POST /auth/login HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "username": "admin", "password": "wrong_password" }

In this example, the attacker repeatedly submits incorrect login credentials (i.e., “wrong_password”) to the ‘/auth/login’ endpoint. Due to the vulnerability, the system eventually fails to limit these excessive attempts, allowing the attacker to bypass the authentication.

Mitigation and Prevention

The primary mitigation method for CVE-2025-2413 is to apply the vendor patch. Akinsoft has released a fix for this vulnerability in the newer versions of ProKuafor. All users running affected versions should upgrade immediately.
As a temporary solution or additional security layer, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and prevent exploitation attempts. These tools can monitor and limit the number of failed authentication attempts, thus offering protection against the vulnerability.
This vulnerability emphasizes the importance of implementing adequate rate-limiting on authentication attempts to prevent brute force attacks. Regular patching and updating of software are also critical in maintaining a secure system environment.
