Cross Site Scripting (XSS)įor details on XSS: Cross-site Scripting Buffer Overflows and Format String Errors Buffer Overflows (BFO)Ī buffer overflow or memory corruption attack is a programming condition which allows overflowing of valid data beyond its prelocated storage limit in memory.įor details on Buffer Overflows: Testing for Buffer Overflow The remainder of this appendix presents a number of fuzz vector categories. In this category, the total number of requests is dependent on the number of fuzz vectors specified. Testing against Cross Site Scripting (XSS) by sending the following fuzz vectors: Replacive fuzzing can be defined as the process of fuzzing part of a request by means of replacing it with a set value. This would generate a total of 16^8 requests of the form: ) falls under the category of recursive fuzzing. Selecting “8302fa3b” as a part of the request to be fuzzed against the set hexadecimal alphabet (i.e. Recursive fuzzing can be defined as the process of fuzzing a part of a request by iterating through all the possible combinations of a set alphabet. We examine and define each category in the sub-sections that follow. In the case of stateless network protocol fuzzing (like HTTP(S)) two broad categories exist: Once an error has been discovered identifying and exploiting a potential vulnerability is where skill is required. This is the simple part of the discovery phase. Generally one looks for error conditions that are generated in an application as a result of fuzzing. Fuzzing is the “kitchen sink” approach to testing the response of an application to parameter manipulation. The following are fuzzing vectors which can be used with ZAP, or another fuzzer.
