DESCRIPTION:
DarkFig has discovered a security issue in microforum, which can be
exploited by malicious people to disclose sensitive information.

The problem is caused due to user credentials being stored insecurely
in the "membres/members.dat" file inside the web root. This can be
exploited to disclose usernames and encrypted passwords (MD5 sum).

The security issue has been confirmed in version 0.4c. Other versions
may also be affected.

SOLUTION:
Restrict web access to the "membres/members.dat" file (e.g. with a
.htaccess file).
