Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Cross-site scripting (XSS) vulnerability in the Adobe Flex SDK 3.x and 4.x before 4.6 allows remote attackers to inject arbitrary web script or HTML via vectors related to the loading of modules from different domains.

Cross-site scripting (XSS) vulnerability in index.template.html in the express-install templates in the SDK in Adobe Flex before 3.4, when the installed Flash version is older than a specified requiredMajorVersion value, allows remote attackers to inject arbitrary web script or HTML via the query string.

Multiple cross-site scripting (XSS) vulnerabilities in the Flex 3 History Management feature in Adobe Flex 3.0.1 SDK and Flex Builder 3, and generated applications, allow remote attackers to inject arbitrary web script or HTML via the anchor identifier to (1) client-side-detection-with-history/history/historyFrame.html, (2) express-installation-with-history/history/historyFrame.html, or (3) no-player-detection-with-history/history/historyFrame.html in templates/html-templates/. NOTE: Firefox 2.0 and possibly other browsers prevent exploitation.
