Testing for business logic vulnerabilities
Unraveling vulnerabilities within an API’s business logic is a challenging but crucial aspect of security evaluations. Contrary to what we do with common flaws derived from coding errors or infrastructure misconfigurations, these types of vulnerabilities target the API’s designed and intended functionalities. To identify these chinks in the armor, security testers must possess a comprehensive understanding of the application’s business processes and how they might be contorted. This in-depth examination involves meticulously analyzing the application’s workflows, user permissions, and data flow to unearth potential weaknesses.
Discovering business logic vulnerabilities within APIs is not straightforward since they can easily bypass traditional security watchdogs. Automated tools might miss these hidden weaknesses since they don’t necessarily involve strange inputs or well-known exploit patterns. Instead...
