The system allows the upload of the xml file may lead to xss-vulnerability warning-the black bar safety net

The system allows uploading XML files, which may lead to an XSS vulnerability warning related to the black bar safety net. The XML file may contain an XML-stylesheet tag, which can specify an XSL file to the XML file format and output. In the XSL output, any HTML code, including the <script> tag, can be output, potentially leading to an alert. However, the XML formatted script permissions are relatively small, limiting many operations. The vulnerability proof includes an alert in the code area of alert.xml and repair solutions involve prohibiting the upload of XML files and the need to filter XML operations
