Apache Maven is a broadly-used build manager for Java projects, allowing for the central management of a project's build, reporting and documentation. Many application functions that do this can be rewritten to deliver the same behavior in a safer way. In this specific case, the path is considered valid if it starts with the string "/safe_dir/". This noncompliant code example accepts a file path as a command-line argument and uses the File.getAbsolutePath() method to obtain the absolute file path. After validating the supplied input, the application should append the input to the base directory and use a platform filesystem API to canonicalize the path. I tried using multiple ways which are present on the web to fix it but still, Gitlab marked it as Path Traversal Vulnerability. And in-the-wild attacks are expected imminently. Pearson collects name, contact information and other information specified on the entry form for the contest or drawing to conduct the contest or drawing. 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. If that isn't possible for the required functionality, then the validation should verify that the input contains only permitted content, such as purely alphanumeric characters. Most basic Path Traversal attacks can be made through the use of "../" characters sequence to alter the resource location requested from a URL. Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Hotspot).
