------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
Two persistent Cross-Site Scripting vulnerabilities have been found in
osTicket. These issues exists due to the lack of output encoding on user
input. These vulnerabilities allow an attacker to inject malicious
JavaScript code into the application. This code will then be executed
within the browser of a user who views the dashboard. The
attacker-supplied code can perform a wide variety of actions, such as
stealing victims' session tokens or login credentials, performing
arbitrary actions on their behalf.

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
These issues were successfully tested on osTicket version 1.9.12.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
osTicket version 1.9.15 and osTicket version 1.10 are released that
address these vulnerabilities.
