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.

Exploitation public PoC (EG-KEV: weaponized) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
