Authored by Aishwarya Iyer

An issue was discovered in osTicket versions before 1.10.7 and 1.12.x before 1.12.1. Stored XSS exists in setup/install.php. It was observed that no input sanitization was provided in the firstname and lastname fields of the application. The insertion of malicious queries in those fields leads to the execution of those queries. This can further lead to cookie stealing or other malicious actions.

1. Description

An issue was discovered in osTicket before 1.10.7 and 1.12.x before 1.12.1.
Stored XSS exists in setup/install.php. It was observed that no input
sanitization was provided in the firstname and lastname fields of the

the execution of those queries. This can further lead to cookie stealing or
other malicious actions.

2. Proof of Concept

Steps to Reproduce:
- While setting up the osTicket application in the setup/install.php page
insert the XSS payload into the first name and last name field.
- After filling in all the other details and clicking on 'continue', it is
observed that there is no validation for the first name and last name field
and the malicious payload is stored and a new agent is created.
- Login as that agent and navigate to "agents" tab where we will find the
inserted payload in the firstname and Lastname field.
- Click on the firstname value and see the payload gets executed
