They should possess the ability to easily track or identify potential fraud or anomalies end-to-end. Environments Affected All.

Structured exception handling is always preferred as it is easier to cover 100% of code. On the other hand it is very hard to cover 100% of all errors in languages that do not have exceptions, such as PHP 4. Code that covers 100% of

Contact author: Eoin Keary application error message security vulnerability An important aspect of secure application development is to prevent information leakage. Error messages give an attacker great insight into the inner workings of an application. The purpose of reviewing the https://www.owasp.org/index.php/Error_Handling,_Auditing_and_Logging Error Handling code is to assure the application fails safely under all possible error conditions, expected and unexpected. No sensitive information is presented to the user when an error occurs. For example SQL injection is much tougher to successfully pull off without some healthy error messages. It lessens the attack footprint and our attacker would have to resort to use “blind https://www.owasp.org/index.php/Error_Handling SQL injection” which is more difficult and time consuming. A well-planned error/exception handling strategy is important for three reasons: Good error handling does not give an attacker any information which is a means to an end, attacking the application A proper centralised error strategy is easier to maintain and reduces the chance of any uncaught errors “Bubbling up” to the front end of an application. Information leakage can lead to social engineering exploits. Some development languages provide checked exceptions which mean that the compiler shall complain if an exception for a particular API call is not caught Java and C# are good examples of this. Languages like C++ and C do not provide this safety net. Languages with checked exception handling still are prone to information leakage as not all types of error are checked for. When an exception or error is thrown we also need to log this occurrence. Sometimes this is due to bad development, but it can be the result of an attack or some other service your application relies on failing. All code paths that can cause an excepti

Extended Description An attacker may discover this type of error, as forcing these errors can occur with a variety of corrupt input. Common ConsequencesScopeEffect IntegrityConfidentialityTechnical Impact: Read application data; Modify files or directoriesGenerally, the consequences of improper error handling are the disclosure of the internal workings of the application to the attacker, providing details to use in further attacks. Web applications that do not properly handle error conditions frequently generate error messages such as stack traces, detailed diagnostics, and other inner details of the application. Demonstrative ExamplesExample 1In the snippet below, an unchecked runtime exception thrown from within the try block may cause the container to display its default error page (which may contain a full stack trace, among other things).(Bad Code)Example Language: JavaPublic void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { ... } catch (ApplicationSpecificException ase) { logger.error("Caught: " + ase.toString()); } } Potential Mitigations Use a standard exception handling mechanism to be sure that your application properly handles all types of processing errors. All error messages sent to the user should contain as little detail as necessary to explain what happened. If the error was caused by unexpected and likely malicious input, it may be appropriate to send the user no error message other than a simple "could not process the request" response. The details of the error and its cause should be recorded in a detailed diagnosti
