DESCRIPTION:
Multiple vulnerabilities have been discovered in Mbedthis AppWeb.
Some currently have an unknown impact and others may be exploited by
malicious people to gain knowledge of sensitive information or bypass
certain security restrictions.

1) Certain handlers matching by extension won't match URIs containing
a trailing "." or " " character. This may potentially disclose the
source of scripts, which may contain sensitive information.

2) A canonicalization error when determining access rights can be
exploited to gain access to restricted resources via a specially
crafted URI containing mixed case characters.

3) User messages may disclose system information when access is
denied.

4) Some handlers reportedly don't handle HEAD and TRACE requests
correctly. The impact is currently unknown.

5) Authorisation configuration directives are reportedly parsed
incorrectly by VirtualHosts. The impact is currently unknown.

SOLUTION:
The vulnerability has been fixed in versions 1.0.4 and 1.1.3.
