CVE-2024-27125Network attack vector

Browser script execution via undisclosed XSS locus

Published Sep 6, 2024 · Updated Sep 6, 2024

Cross-site scripting in QNAP Helpdesk 3.3.x before 3.3.1 allows remote authenticated users with administrator access to inject code. QNAP has not published the affected input, handler, or missing output-encoding operation, so the exact injection locus is undisclosed. Administrator privileges and user interaction are required; successful exploitation executes attacker-supplied script in another user's browser, affecting confidentiality and integrity without interrupting service.
