### Description

The Nitro API in Citrix NetScaler before 10.5 build 52.3nc uses an incorrect Content-Type when returning an error message, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the file_name JSON member in params/xen_hotfix/0 to nitro/v1/config/xen_hotfix.
