Teltonika Gateway TRB245 Stored Cross-site Scripting
LowSynopsis
A stored cross-site scripting vulnerability exists in the Web UI. A remote, authenticated attacker is able to inject malicious client-side code into the 'URL/ Host / Connection' form in the 'DATA TO SERVER' configuration section. An attacker with low privileges could exploit this to steal session details from a higher privileged user.
Proof of Concept
In the below screenshot we can see the tester has added some script tags into the 'URL/ Host / Connection' form.
“<script>alert(‘1337 hacks’)</script>
When the tester selects ‘Save & Apply’ this change you will be redirected to the list of data sensors and the injected javascript will execute.
