Title: Perl Web Server Path Traversal Vulnerability
Severity: MODERATE
Description:
HTTP servers map the file system to a virtual directory structure. The root of the virtual directory structure, or the / directory, is called the ServerRoot.
Generally, the ServerRoot is several directory levels below the real file system root. As a security feature, the web server must ensure that documents above the ServerRoot are not served to remote users.
Perl Web Server, an experimental cross-platform web server project, does not prevent a remote user from requesting documents outside the ServerRoot. This means that if an attacker knows the location of a sensitive file relative to the ServerRoot, he can retrieve the contents of the file.
