QTS 4.4.2.1270 build 20200410 and later QTS 4.4.1.1261 build 20200330 and later QTS 4.3.6.1263 build 20200330 and later QTS 4.3.4.1282 build 20200408 and later QTS 4.3.3.1252 build 20200409 and later QTS 4.2.6 build 20200421 and later
Summary dbcve.org
This is a cross-site scripting (XSS) vulnerability in QNAP QTS firmware that allows remote attackers to inject malicious JavaScript code into the web interface. When other users access the affected interface, the injected script executes in their browser context, potentially stealing session cookies or performing actions on behalf of authenticated users.
Mitigation
Upgrade QTS to one of the fixed versions (4.4.2.1270, 4.4.1.1261, 4.3.6.1263, 4.3.4.1282, 4.3.3.1252, or 4.2.6 or later depending on your current branch). If patching is not immediately feasible, restrict administrative interface access to trusted networks only.
