Path Traversal occurrences in Aurora
An issue was discovered in AfterLogic Aurora through 7.7.9 and WebMail Pro through 7.7.9. They allow directory traversal to read files (such as a data/settings/settings.xml file containing admin panel credentials), as demonstrated by dav/server.php/files/personal/%2e%2e when using the caldav_public_user account (with caldav_public_user as its password). (2021-03-07, CVE-2021-26294)
An issue was discovered in AfterLogic Aurora through 8.5.3 and WebMail Pro through 8.5.3, when DAV is enabled. They allow directory traversal to create new files (such as an executable file under the web root). This is related to DAVServer.php in 8.x and DAV/Server.php in 7.x. (2021-03-04, CVE-2021-26293)
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).
