Authentication bypass vulnerability could allow attackers to perform various malicious operations by bypassing the device authentication mechanism.
What's the issue - Authentication bypass exploit is mainly due to a weak authentication mechanism.
Organizations failing to enforce strong access policy and authentication controls could allow an attacker to bypass authentication.
Attackers look for unprotected files, gains access to those unsecured files, gathers information and then attempt to attack protected applications by bypassing the authentication system.
Most websites use scripts and back-end databases to enforce authentication. Moreover, web-form-based authentication is executed in the client-side web browser scripts or through parameters posted through the web browser. It just takes the attacker to manipulate the values contained in the Web forms or in the parameters to bypass authentication.
Attackers could also bypass the authentication mechanism by stealing the valid session IDs or cookies.
Examples of ‘Authentication Bypass Vulnerability’
Example 1 - Researchers detected a critical vulnerability in the SHAREit app that could allow attackers to bypass Android device authentication. However, to exploit this vulnerability, the exact path of the target file is required.
Researchers noted two distinct database files related to SHAREit app that might be useful for exploitation,
The SHAREit MediaStore database contains file information such as file name, type, size, path, and more other information.
Example 2 - Researchers discovered a WhatsApp-iOS vulnerability that could allow attackers to access users’ WhatsApp chats by bypassing the Face ID or Touch ID security mechanism.
The vulnerability resides in the iOS sharing sheet and in order to bypass the security mechanism, attackers must share something via the iOS sharing sheet and then tap on the WhatsApp icon.
