DESCRIPTION:
Craig Freyman has discovered a vulnerability in Sysax Multi Server,
which can be exploited by malicious users to disclose potentially
sensitive information.

Input passed to the "file" POST parameter in scgi (when "sid" is
valid) is not properly verified before being used to display files.
This can be exploited to disclose the contents of arbitrary files via
directory traversal sequences.

Successful exploitation requires that the "HTTP File Server" feature
is enabled.

The vulnerability is confirmed in version 5.57. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Craig Freyman
