What is CVE-2019-14750?

A vulnerability has been identified in osTicket prior to versions 1.10.7 and 1.12.1, where a Stored Cross-Site Scripting (XSS) flaw exists in the 'setup/install.php' file. The application fails to properly sanitize input provided in the firstname and lastname fields. This oversight enables an attacker to insert malicious scripts, which can be executed within the context of a user’s session, potentially leading to unauthorized access to cookies and other sensitive actions. Proper input sanitization measures are crucial to prevent such vulnerabilities.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
