CVE-2023-1248Network attack vector

Browser script execution via Ticket Actions input validation

Published Mar 20, 2023 · Updated Feb 26, 2025

Cross-site scripting in OTRS Ticket Actions allows remote attackers to run script in a user's browser on affected OTRS versions. The vendor identifies improper input validation in Ticket Actions but does not disclose the affected parameter, output context, or escaping failure. Successful exploitation requires user interaction and exposes or modifies browser-accessible data in OTRS 7.0.x before 7.0.42 and OTRS Community Edition 6.0.1 through 6.0.34.
