Explore potential error handling issues, the risks associated with them, and learn how to avoid them.
- Error handling is an important part…of application development.…It allows the developer to prevent the application…from abnormal termination…while also providing a great place…for troubleshooting break points…when issues do arise.…What makes it powerful for developers…also makes it attractive for bad actors.…One of the most frequent vulnerabilities…comes from information disclosure…through error messaging.…
In these vulnerabilities the application raises…an error that produces an error status.…This error status usually results…in a message or a redirect in the web world.…The vulnerability arises when that error message…discloses information such as a stack trace…or a database dump.…This information can be very valuable…for an attacker trying to gain entry…to your system.…
Even the disclosure of your internal error codes…can be used to attack your system.…Even how you raise an error…can provide an attack point.…One of the most common issues…that I have seen in applications…of every type is in user authentication flows.…
