Path Traversal occurrences in Nexus Repository Manager
Sonatype Nexus Repository Manager 3.x before 3.31.0 allows a remote authenticated attacker to get a list of blob files and read the content of a blob file (via a GET request) without having been granted access. (2021-06-18, CVE-2021-34553)
Sonatype Nexus Repository Manager 3.x before 3.30.1 allows a remote attacker to get a list of files and directories that exist in a UI-related folder via directory traversal (no customer-specific data is exposed). (2021-04-27, CVE-2021-30635)
A Directory Traversal issue was discovered in Sonatype Nexus Repository Manager 2.x before 2.14.19. A user that requests a crafted path can traverse up the file system to get access to content on disk (that the user running nxrm also has access to). (2020-10-12, CVE-2020-15012)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
