Newtec Satellite Modem MDM6000 2.2.5 Cross-Site Scripting Vulnerability


Vendor: Newtec Cy N.V.
Product web page: http://www.newtec.eu
Affected version: 2.2.5.67852
2.2.4.64193
1.3.8.56435

Summary: The MDM6000 modem is typically installed at both ends
of a point-to-point satellite link or at the remote sites of a
star network. The unit can work as a modulator, demodulator or
modem depending on the network configuration and integrates
seamlessly with terrestrial IP networks and equipment. The modem
is in full compliance with the DVB-S2 and DVB-S2X standards to
achieve barrier-breaking efficiency at maximum service availability.

Desc: Newtec Satellite Modem MDM6000 suffers from multiple reflected
cross-site scripting vulnerabilities when input passed via several
parameters to several scripts is not properly sanitized before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

Tested on: lighttpd/1.4.28
