Vendor

Affected versions

1.1.49

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.
