Reflected XSS via unsanitized HL7 route source
Published Jan 20, 2026 · Updated Jan 20, 2026
Reflected XSS in MedDream PACS Premium 7.3.6.870 allows remote attackers to execute JavaScript through a crafted URL. The Pacs/modifyHL7Route.php script inserts the attacker-controlled source query parameter into an HTML database-error message without sanitization. Exploitation requires an authenticated user to open the URL, and the injected script executes in that user's browser session.
