Path Traversal occurrences in Infoscale Operations Manager
An issue was discovered in Veritas InfoScale Operations Manager (VIOM) before 7.4.2 Patch 600 and 8.x before 8.0.0 Patch 100. The web server fails to sanitize admin/cgi-bin/rulemgr.pl/getfile/ input data, allowing a remote authenticated administrator to read arbitrary files on the system via Directory Traversal. By manipulating the resource name in GET requests referring to files with absolute paths, it is possible to access arbitrary files stored on the filesystem, including application source code, configuration files, and critical system files. (2022-03-04, CVE-2022-26484)
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).
