Record your progression from Apprentice to Expert. On Windows, both ../ and ..\ are valid directory traversal sequences, and an equivalent attack to retrieve a standard operating system file would be: Many applications that place user input into file paths implement some kind of defense against path traversal attacks, and these can often be circumvented. Well occasionally send you account related emails. These file links must be fully resolved before any file validation operations are performed. The quickest, but probably least practical solution, is to replace the dynamic file name with a hardcoded value, example in Java: // BAD CODE File f = new File (request.getParameter ("fileName")) // GOOD CODE File f = new File ("config.properties"); This vulnerability applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. input path not canonicalized vulnerability fix java The same secret key can be used to encrypt multiple messages in GCM mode, but it is very important that a different initialization vector (IV) be used for each message. Here the path of the file mentioned above is program.txt but this path is not absolute (i.e. An attacker could provide an input path of "/safe_dir/../" that would pass the validation step.
