I think 4 and certainly 5 are rather extreme nitpicks, even to my standards . getPath () method is a part of File class. However, the canonicalization process sees the double dot as a traversal to the parent directory and hence when canonicized the path would become just "/". It uses the "AES/CBC/PKCS5Padding" transformation, which the Java documentation guarantees to be available on all conforming implementations of the Java platform. An attacker could provide an input path of "/safe_dir/../" that would pass the validation step. input path not canonicalized vulnerability fix java A Community-Developed List of Software & Hardware Weakness Types, Class: Not Language-Specific (Undetermined Prevalence), Technical Impact: Bypass Protection Mechanism. This table specifies different individual consequences associated with the weakness. After validating the user-supplied input, make the application verify that the canonicalized path starts with the expected base directory. A brute-force attack against 128-bit AES keys would take billions of years with current computational resources, so absent a cryptographic weakness in AES, 128-bit keys are likely suitable for secure encryption. Cyber Skills Training - RangeForce Parameters: This function does not accept any parameters. An attacker may manipulate a URL in such a way that the web site will execute or reveal the contents of arbitrary files anywhere on the web server. Below is a simple Java code snippet that can be used to validate the canonical path of a file based on user input: File file = new File (BASE_DIRECTORY, userInput); This keeps Java on your computer but the browser wont be able to touch it. The getCanonicalPath() method throws a security exception when used within applets because it reveals too much information about the host machine. Consider a shopping application that displays images of items for sale. Make sure that your application does not decode the same input twice.
