Description
The Campbell Scientific CSI Web Server supports a command that will return the most recent file that matches a given expression. A specially crafted expression can lead to a path traversal vulnerability. This command combined with a specially crafted expression allows anonymous, unauthenticated access (allowed by default) by an attacker to files and directories outside of the webserver root directory they should be restricted to.
