Mishandling of Exceptional Conditions Vulnerability: A Detailed Study

Mishandling of exceptional conditions is ranked as 10 in the OWASP Top 10 list in 2025, consisting of 24 sub-vulnerabilities. Web applications fail to predict, identify, and react to an unusual behavior of an application, revealing sensitive information in the form of a stack trace or error handling. Which is prone to security vulnerabilities like server crashes, outages, and sometimes a DDOS attack. Since these vulnerabilities expose sensitive information for attackers in gaining attacked system information, when exploited, this may cause serious reputational damage to the organization. In this research paper we will be talking about real-time test cases and possible mitigation methodologies. We will discuss possible remediation techniques that can be adopted by the developers when developing the product.
