Description: Functionality vulnerability refers to a weakness in software that allows an attacker to exploit its functionality in unintended ways. This can occur when an application offers features that, if not adequately protected, can be manipulated to perform unauthorized actions. For example, a system that allows users to upload files could be vulnerable if proper controls over the type and size of allowed files are not implemented. Functionality vulnerabilities can arise from errors in programming logic, incorrect configurations, or lack of input validation. These weaknesses are particularly critical in software applications, where user interaction is constant and can be exploited by attackers to gain unauthorized access to sensitive data or compromise system integrity. Identifying and mitigating these vulnerabilities is essential to ensure application security and protect user information. Penetration testing is a key tool in this process, as it allows for simulating attacks and assessing the software’s resilience against potential exploitations.
