Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A cross-site scripting (XSS) vulnerability in QNAP Photo Station allows remote attackers to inject malicious scripts through unspecified vectors in the web interface. The vulnerability stems from insufficient input validation or output encoding in the Photo Station web application, enabling authenticated or unauthenticated attackers to execute arbitrary JavaScript in the context of other users' sessions.

MitigationUpdate Photo Station to version 6.0.18 or later as released on 2021/09/01. Until the update can be applied, consider restricting network access to the Photo Station interface or disabling the service if possible.
