The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0228 advisory.

    Git is a distributed revision control system with a decentralized architecture. As opposed to centralized     version control systems with a client-server model, Git ensures that each working copy of a Git repository     is an exact copy with complete revision history. This not only allows the user to work on and contribute     to projects without the need to have permission to push the changes to their official repositories, but     also makes it possible for the user to work with no network connection.

    The following packages have been upgraded to a later upstream version: git (2.18.2). (BZ#1784057)

    Security Fix(es):

    * git: Remote code execution in recursive clones with nested submodules (CVE-2019-1387)

    * git: Arbitrary path overwriting via export-marks in-stream command feature (CVE-2019-1348)

    * git: Recursive submodule cloning allows using git directory twice with synonymous directory name written     in .git/ (CVE-2019-1349)

    * git: Files inside the .git directory may be overwritten during cloning via NTFS Alternate Data Streams     (CVE-2019-1352)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2019:4356 advisory.

  - git: Arbitrary path overwriting via export-marks in-stream command feature (CVE-2019-1348)

  - git: Recursive submodule cloning allows using git directory twice with synonymous directory name written     in .git/ (CVE-2019-1349)

  - git: Files inside the .git directory may be overwritten during cloning via NTFS Alternate Data Streams     (CVE-2019-1352)

  - git: Remote code execution in recursive clones with nested submodules (CVE-2019-1387)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of git installed on the remote host is prior to 2.23.1-0. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1943 advisory.

    A flaw was found in the git fast-import command where it provides the export-marks feature that may     unexpectedly overwrite arbitrary paths. An attacker can abuse this flaw if they can control the input     passed to the fast-import command by using the export-marks feature and overwrite arbitrary files, but     would not have complete control on the content of the file. (CVE-2019-1348)

    An improper input validation flaw was discovered in git in the way it handles git submodules. A remote     attacker could abuse this flaw to trick a victim user into recursively cloning a malicious repository,     which, under certain circumstances, could fool git into using the same git directory twice and potentially     cause remote code execution. (CVE-2019-1349)

    A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka     'Git for Visual Studio Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2019-1349,     CVE-2019-1352, CVE-2019-1354, CVE-2019-1387. (CVE-2019-1350)

    A tampering vulnerability exists when Git for Visual Studio improperly handles virtual drive paths, aka     'Git for Visual Studio Tampering Vulnerability'. (CVE-2019-1351)

    A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka     'Git for Visual Studio Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2019-1349,     CVE-2019-1350, CVE-2019-1354, CVE-2019-1387. (CVE-2019-1352)

    An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3,     v2.16.6, v2.15.4, and v2.14.6. When running Git in the Windows Subsystem for Linux (also known as WSL)     while accessing a working directory on a regular Windows drive, none of the NTFS protections were active.
    (CVE-2019-1353)

    A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka     'Git for Visual Studio Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2019-1349,     CVE-2019-1350, CVE-2019-1352, CVE-2019-1387. (CVE-2019-1354)

    A flaw was discovered where git improperly validates submodules' names used to construct git metadata     paths and does not prevent them from being nested in existing directories used to store another     submodule's metadata. A remote attacker could abuse this flaw to trick a victim user into cloning a     malicious repository containing submodules, which, when recursively cloned, would trigger the flaw and     remotely execute code on the victim's machine. (CVE-2019-1387)

    A security bypass was discovered in git, which allows arbitrary commands to be executed during the update     of git submodules. A remote attacker may trick a victim user into cloning a malicious repository that     initially looks fine, allowing access to bypass the security mechanisms that prevent the execution of     arbitrary commands during the submodule initialization. After following an update of the repository and     the submodules done by the victim user, vulnerable versions of git may use the update setting in the     .gitmodules file and execute arbitrary commands. (CVE-2019-19604)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0109 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-1351:
    A tampering vulnerability exists when Git for Visual Studio improperly handles virtual drive paths, aka     'Git for Visual Studio Tampering Vulnerability'.

    CVE-2019-1354:
    A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka     'Git for Visual Studio Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2019-1349,     CVE-2019-1350, CVE-2019-1352, CVE-2019-1387.

    CVE-2019-1387:
    An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3,     v2.16.6, v2.15.4, and v2.14.6. Recursive clones are currently affected by a vulnerability that is caused     by too-lax validation of submodule names, allowing very targeted attacks via remote code execution in     recursive clones.

    CVE-2020-5260:
    Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials     to a host controlled by an attacker. Git uses external credential helper programs to store and retrieve     passwords or other credentials from secure storage provided by the operating system. Specially-crafted     URLs that contain an encoded newline can inject unintended values into the credential helper protocol     stream, causing the credential helper to retrieve the password for one server (e.g., good.example.com) for     an HTTP request being made to another server (e.g., evil.example.com), resulting in credentials for the     former being sent to the latter. There are no restrictions on the relationship between the two, meaning     that an attacker can craft a URL that will present stored credentials for any host to a host of their     choosing. The vulnerability can be triggered by feeding a malicious URL to git clone. However, the     affected URLs look rather suspicious; the likely vector would be through systems which automatically clone     URLs not visible to the user, such as Git submodules, or package systems built around Git. The problem has     been patched in the versions published on April 14th, 2020, going back to v2.17.x. Anyone wishing to     backport the change further can do so by applying commit 9a6bbee (the full release includes extra checks     for git fsck, but that commit is sufficient to protect clients against the vulnerability). The patched     versions are: 2.17.4, 2.18.3, 2.19.4, 2.20.3, 2.21.2, 2.22.3, 2.23.2, 2.24.2, 2.25.3, 2.26.1.

    CVE-2020-11008:
    Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials     to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix     for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker     cannot control which one). Git uses external credential helper programs to store and retrieve passwords     or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are     considered illegal as of the recently published Git versions can cause Git to send a blank pattern to     helpers, missing hostname and protocol fields. Many helpers will interpret this as matching _any_ URL, and     will return some unspecified stored password, leaking the password to an attacker's server. The     vulnerability can be triggered by feeding a malicious URL to `git clone`. However, the affected URLs look     rather suspicious; the likely vector would be through systems which automatically clone URLs not visible     to the user, such as Git submodules, or package systems built around Git. The root of the problem is in     Git itself, which should not be feeding blank input to helpers. However, the ability to exploit the     vulnerability in practice depends on which helpers are in use. Credential helpers which are known to     trigger the vulnerability: - Git's store helper - Git's cache helper - the osxkeychain helper that     ships in Git's contrib directory Credential helpers which are known to be safe even with vulnerable     versions of Git: - Git Credential Manager for Windows Any helper not in this list should be assumed to     trigger the vulnerability.

執行 CORE 5.05 / MAIN 5.05 版的遠端 NewStart CGSL 主機上安裝的 git 套件受到多個弱點影響：

  - 在 Git v2.24.1 之前的版本、v2.23.1、v2.22.2、v2.21.1、v2.20.2、v2.19.3、v2.18.2、v2.17.3、v2.16.6、v2.15.4 和 v2.14.6 版中發現一個問題。遞回複製目前受到因子模組名稱驗證過於寬鬆造成的弱點影響，允許透過遞回複製中的遠端程式碼執行發動極有針對性的攻擊。(CVE-2019-1387)

  - 受影響的 Git 版本有一個弱點，可誘騙 Git 將私密憑證傳送至攻擊者控制的主機。Git 使用外部憑證協助程式來儲存和擷取作業系統提供的安全儲存中的密碼或其他憑證。包含編碼新行的特別建構 URL 可將非預定值插入憑證協助程式通訊協定資料流，造成憑證協助程式擷取一台伺服器 (例如 good.example.com) 的密碼，以向其他伺服器發出 HTTP 要求 (例如 evil.example.com)，進而導致將前者的憑證傳送至後者。對兩者之間的關係沒有限制，這表示攻擊者可以特製 URL，將所儲存的任何主機憑證提供給他們選擇的主機。藉由提供惡意 URL 至 git clone 可觸發此弱點。不過，受影響的 URL 看起來相當可疑；可能的途徑會是自動複製對使用者不可見的 URL 的系統 (例如 Git 子模組)，或是圍繞 Git 構建的套件系統。此問題已在 2020 年 4 月 14 日發佈的版本中得到修補，回溯至 v2.17.x 版本。希望進一步反向移植變更的所有使用者皆可套用 commit 9a6bbee  (完整版本包含對 git fsck 的額外檢查，但該 commit 足以保護用戶端不受此弱點影響)。修補的版本為：2.17.4、2.18.3、2.19.4、2.20.3、2.21.2、2.22.3、2.23.2、2.24.2、2.25.3、2.26.1。
