Description: The ‘User Authentication Bypass’ is a method used to circumvent the authentication process, allowing unauthorized access to systems, applications, or networks. This type of vulnerability occurs when an attacker gains access to restricted resources without providing the appropriate credentials, such as a username and password. The main characteristics of this type of attack include exploiting flaws in the authentication implementation, session manipulation, or using social engineering techniques. The relevance of authentication bypass lies in its ability to compromise the security of critical systems, which can result in the exposure of sensitive data, alteration of information, or complete control of a system by an attacker. This type of vulnerability is particularly concerning in environments where data protection is paramount, such as in various sectors, including finance, healthcare, and government, where security breaches can have devastating consequences.
