Reported by

This issue was reported to the vendor by Christian Schneider (@cschneider4711)
following a responsible disclosure process.

Severity

Medium

Exploitability

No authentication required

Description

Using a specially crafted URL to access the MapAPI it is possible to issue
HTTP(S) GET requests originating from the attacked server (behind the firewall)
and to read the response. This enables attackers to access web servers that are not
exposed to be accessed from the internet and thus allows to pivot further into the
targeted network.

Proof of concept

Due to the responsible disclosure process chosen and to not harm unpatched systems,
no concrete exploit code will be presented in this advisory.

Migration

MapSuite MapAPI 1.0.x users should upgrade to 1.0.36 or later as soon as possible.
MapSuite MapAPI 1.1.x users should upgrade to 1.1.49 or later as soon as possible.
