Access Restricted: A Study of Broken Access Control Vulnerabilities

Broken access control vulnerability is ranked No.1 in OWASP Top 10 list in 2021. This means that it is the most commonly used exploited weakness in the web applications by attackers today. Because if an attacker can exploit this vulnerability, they can gain control rights and potentially compromise the entire web application. From that point forward, the attacker can execute various attacks depending on their objectives. That’s what makes it the most purposeful. In this research, we will reveal the security vulnerability of the access control in a web applications system. We will explore case studies of real-world attacks that leverage broken access control, providing a contextual understanding of the impact and implications of these vulnerabilities. Through this research, we aim to contribute to the ongoing efforts to enhance web application security and mitigate the risks associated with broken access control vulnerabilities. We will examine vulnerabilities in web applications that attackers can use to compromise access. Finally, we discuss the protection and security measures that should be taken against attackers who use this vulnerability.
