  • Security Analysis of Firefox Webextensions
    6.857: Computer and Network Security Due: May 16, 2018 Security Analysis of Firefox WebExtensions Srilaya Bhavaraju, Tara Smith, Benny Zhang srilayab, tsmith12, felicity Abstract With the deprecation of Legacy addons, Mozilla recently introduced the WebExtensions API for the development of Firefox browser extensions. WebExtensions was designed for cross-browser compatibility and in response to several issues in the legacy addon model. We performed a security analysis of the new WebExtensions model. The goal of this paper is to analyze how well WebExtensions responds to threats in the previous legacy model as well as identify any potential vulnerabilities in the new model. 1 Introduction Firefox release 57, otherwise known as Firefox Quantum, brings a large overhaul to the open-source web browser. Major changes with this release include the deprecation of its initial XUL/XPCOM/XBL extensions API to shift to its own WebExtensions API. This WebExtensions API is currently in use by both Google Chrome and Opera, but Firefox distinguishes itself with further restrictions and additional functionalities. Mozilla’s goals with the new extension API is to support cross-browser extension development, as well as offer greater security than the XPCOM API. Our goal in this paper is to analyze how well the WebExtensions model responds to the vulnerabilities present in legacy addons and discuss any potential vulnerabilities in the new model. We present the old security model of Firefox extensions and examine the new model by looking at the structure, permissions model, and extension review process. We then identify various threats and attacks that may occur or have occurred before moving onto recommendations.

  • Multi-File Course Files Upload Interface and Browsers Not Supporting NPAPI Plugins
    Multi-file Course Files Upload Interface and Browsers Not Supporting NPAPI Plugins Date Published: Mar 23,2017 Category: Product:Browsers_Learn; Version:X9_1 Article No.: 000073448 Product: Blackboard Learn Type:Support Bulletin Bulletin/Advisory Information: Update (Published March 23, 2017) Mozilla has removed Netscape Plugin Application Programming Interface (NPAPI) plugin support from Firefox beginning with version 52, which was released on March 7, 2017. Original Bulletin (Published August 26, 2015) In September 2015, Google Chrome will stop supporting NPAPI plugins. This includes the use of Java in the web browser. Before this date, it is possible to configure Chrome to allow this content; after this date, it will no longer be possible to use the multi-file drag-and-drop interface in Course Files or the Content Collection. The new Edge browser from Microsoft also does not support NPAPI plugins. Users wanting to access the multi-file upload interface should use a browser that supports NPAPI and a Java runtime environment. Blackboard will continue to support this interface, but only on supported web browsers that support NPAPI plugins. Chrome and Edge will continue to be supported browsers, but the multi-file upload interface in Course Files and the Content Collection will not be supported on these browsers. Another possible workaround is to use the the Multiple File Upload feature with in the Content Collection. Simply ZIP the needed files and then use the Upload Zip Package or Download Package function. Enter the Course > Click on Content Collection > Click on Course folder > Click on Upload > Select the function to upload the Zipped folder.

  • FAQ NPAPI for Website
    FAQ NPAPI Q: NPAPI is being de-supported by many browsers. What is Ellucian doing to support browsers going forward for Banner INB and Oracle Forms? As long as NPAPI is supported by a browser, we will continue to test and support our Banner Oracle Forms-based releases, including INB, on that browser. As long as the browser is supported by Oracle Forms and Reports 11gR2, we will continue to test and support our Banner Oracle Forms-based releases according to the supported configurations as documented by Oracle. All Banner XE applications (9.x versions) and all Banner transformed pages will be supported in current releases of Chrome, Firefox, Safari and MS Edge according to our published browser support policy. We will also continue to support IE 10 and 11 for Banner INB to allow customers to share a common browser across administrative applications. At this time, Banner INB will only be supported on IE 10 and IE 11 for as long as Microsoft continues to support this browser. Please refer to Microsoft’s Internet Explorer FAQ where Microsoft states: Internet Explorer 11 will be supported for the life of Windows 7, Windows 8.1, and Windows 10. Q: Will Ellucian support the Chrome browser for Oracle Forms-based applications? All Banner XE applications (9.x versions) and all Banner transformed pages will be supported in current releases of Chrome, Firefox, Safari and MS Edge according to our published browser support policy. As of Chrome version 45 (September 2015), the Google Chrome browser does not support NPAPI, which impacts plugins of all types, including Java, which is required for Banner INB.

  • Kandy Link — Webrtc Gateway Using the Web to Extend the Value of Service Provider Networks
    Kandy Link — WebRTC Gateway Using the Web to Extend the Value of Service Provider Networks The Impact of WebRTC The adoption of the WebRTC standard by all of the major web browser providers creates an enormous opportunity to change the way people communicate. WebRTC makes it possible to engage in a two-way multi-media conversation (voice, video, screen share) without any extra software or purpose-built devices. Any modern device with a mic and speakers is now a full communications endpoint supporting voice, video and col- laboration tools. The simplicity of WebRTC-based communication access is in sharp contrast to traditional communication tools that require users to load a special app or a plugin for each website or ser- vice they use. This issue has gone from annoying to business impacting as many organizations have heightened security policies that preclude users from adding new applications. And since WebRTC leverages HTML5 and HTTPS, its firewall Multiple Deployment Options Kandy Link is deployed in a subscription based, fully managed friendly, meaning it works almost everywhere. model.
