Technical Details & Description:
An auth bypass web vulnerability has been discovered in the official Alfine v2.6 Content Management System.
The web vulnerability allows remote attackers to bypass the basic login protection of the web-application.
The auth bypass web vulnerability is located in the username and password input fields of the admin index.php login file.
Remote attackers are able to inject a classic sql payload to bypass the secure login authentication process.
The security risk of the auth bypass vulnerability is estimated as critical with a cvss (common vulnerability scoring system) count of 8.1.
Exploitation of the remote auth bypass web vulnerability requires no user interaction or privileged web-application user accounts.
Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise.
[+] ./admin (Login)
Proof of Concept (PoC):
The auth bypass vulnerability can be exploited by remote attackers without user interaction or privileged web-application user account.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
Vulnerable File: index.php
Username: '=' 'OR'
Password: '=' 'OR'
Note: Gebruikersnaam(username) and Wachtwoord(Password)
Solution - Fix & Patch:
1. Escape the inputs and use entities
2. Restrict the input fields and disallow the usage of special chars
3. Encode and parse the input of the username and password parameter
4. Use a prepared statement for the login to prevent exploitation
The security risk of the remote auth bypass web vulnerability in the Alfine CMS is estimated as high. (CVSS 8.1)
