Maven. Using a path traversal attack (also known as directory traversal), an attacker can access data stored outside the web root folder (typically . To avoid this problem, validation should occur after canonicalization takes place. I'd also indicate how to possibly handle the key and IV. Base - a weakness The application should validate the user input before processing it. Accelerate penetration testing - find more bugs, more quickly. Even if we changed the path to /input.txt the original code could not load this file as resources are not usually addressable as files on disk. It should verify that the canonicalized path starts with the expected base directory. I would like to receive exclusive offers and hear about products from InformIT and its family of brands. Frequently, these restrictions can be circumvented by an attacker by exploiting a directory traversal or path equivalence vulnerability. To a school, organization, company or government agency, where Pearson collects or processes the personal information in a school setting or on behalf of such organization, company or government agency. Canonicalization without validation is insufficient because an attacker can specify files outside the intended directory. File f = new File (path); return f.getCanonicalPath (); } The problem with the above code is that the validation step occurs before canonicalization occurs. This information is often useful in understanding where a weakness fits within the context of external information sources.
