According to the versions of the git packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - GIT version 2.15.1 and earlier contains a Input     Validation Error vulnerability in Client that can     result in problems including messing up terminal     configuration to RCE. This attack appear to be     exploitable via The user must interact with a malicious     git server, (or have their traffic modified in a MITM     attack).(CVE-2018-1000021)

  - Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before     2.12.5, 2.13.x before 2.13.6, and 2.14.x before 2.14.2     uses unsafe Perl scripts to support subcommands such as     cvsserver, which allows attackers to execute arbitrary     OS commands via shell metacharacters in a module name.
    The vulnerable code is reachable via git-shell even     without CVS support.(CVE-2017-14867)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

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

  - git: git shell function that splits command arguments can lead to arbitrary heap writes. (CVE-2022-39260)

  - Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before 2.12.5, 2.13.x before 2.13.6, and 2.14.x before     2.14.2 uses unsafe Perl scripts to support subcommands such as cvsserver, which allows attackers to     execute arbitrary OS commands via shell metacharacters in a module name. The vulnerable code is reachable     via git-shell even without CVS support. (CVE-2017-14867)

  - Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of     service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of     disk consumption; however, an affected process typically would not survive its attempt to build the data     structure in memory before writing to disk. (CVE-2017-15298)

  - GIT version 2.15.1 and earlier contains a Input Validation Error vulnerability in Client that can result     in problems including messing up terminal configuration to RCE. This attack appear to be exploitable via     The user must interact with a malicious git server, (or have their traffic modified in a MITM attack).
    (CVE-2018-1000021)

  - Git is an open-source distributed revision control system. In affected versions of Git a specially crafted     repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may     cause just-checked out script to be executed while cloning onto a case-insensitive file system such as     NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS). Note that clean/smudge filters     have to be configured for that. Git for Windows configures Git LFS by default, and is therefore     vulnerable. The problem has been patched in the versions published on Tuesday, March 9th, 2021. As a     workaound, if symbolic link support is disabled in Git (e.g. via `git config --global core.symlinks     false`), the described attack won't work. Likewise, if no clean/smudge filters such as Git LFS are     configured globally (i.e. _before_ cloning), the attack is foiled. As always, it is best to avoid cloning     repositories from untrusted sources. The earliest impacted version is 2.14.2. The fix versions are:
    2.30.1, 2.29.3, 2.28.1, 2.27.1, 2.26.3, 2.25.5, 2.24.4, 2.23.4, 2.22.5, 2.21.4, 2.20.5, 2.19.6, 2.18.5,     2.17.62.17.6. (CVE-2021-21300)

  - git_connect_git in connect.c in Git before 2.30.1 allows a repository path to contain a newline character,     which may result in unexpected cross-protocol requests, as demonstrated by the     git://localhost:1234/%0d%0a%0d%0aGET%20/%20HTTP/1.1 substring. (CVE-2021-40330)

  - Git for Windows is a fork of Git containing Windows-specific patches. This vulnerability affects users     working on multi-user machines, where untrusted parties have write access to the same hard disk. Those     untrusted parties could create the folder `C:\.git`, which would be picked up by Git operations run     supposedly outside a repository while searching for a Git directory. Git would then respect any config in     said Git directory. Git Bash users who set `GIT_PS1_SHOWDIRTYSTATE` are vulnerable as well. Users who     installed posh-gitare vulnerable simply by starting a PowerShell. Users of IDEs such as Visual Studio are     vulnerable: simply creating a new project would already read and respect the config specified in     `C:\.git\config`. Users of the Microsoft fork of Git are vulnerable simply by starting a Git Bash. The     problem has been patched in Git for Windows v2.35.2. Users unable to upgrade may create the folder `.git`     on all drives where Git commands are run, and remove read/write access from those folders as a workaround.
    Alternatively, define or extend `GIT_CEILING_DIRECTORIES` to cover the _parent_ directory of the user     profile, e.g. `C:\Users` if the user profile is located in `C:\Users\my-user-name`. (CVE-2022-24765)

  - Git is an open source, scalable, distributed revision control system. Versions prior to 2.30.6, 2.31.5,     2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a     malicious actor. When performing a local clone (where the source and target of the clone are on the same     volume), Git copies the contents of the source's `$GIT_DIR/objects` directory into the destination by     either creating hardlinks to the source contents, or copying them (if hardlinks are disabled via `--no-     hardlinks`). A malicious actor could convince a victim to clone a repository with a symbolic link pointing     at sensitive information on the victim's machine. This can be done either by having the victim clone a     malicious repository on the same machine, or having them clone a malicious repository embedded as a bare     repository via a submodule from any source, provided they clone with the `--recurse-submodules` option.
    Git does not create symbolic links in the `$GIT_DIR/objects` directory. The problem has been patched in     the versions published on 2022-10-18, and backported to v2.30.x. Potential workarounds: Avoid cloning     untrusted repositories using the `--local` optimization when on a shared machine, either by passing the     `--no-local` option to `git clone` or cloning from a URL that uses the `file://` scheme. Alternatively,     avoid cloning repositories from untrusted sources with `--recurse-submodules` or run `git config --global     protocol.file.allow user`. (CVE-2022-39253)

  - Git is a revision control system. Using a specially-crafted repository, Git prior to versions 2.39.2,     2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8 can be tricked into using its     local clone optimization even when using a non-local transport. Though Git will abort local clones whose     source `$GIT_DIR/objects` directory contains symbolic links, the `objects` directory itself may still be a     symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's     filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar     manner as CVE-2022-39253. A fix has been prepared and will appear in v2.39.2 v2.38.4 v2.37.6 v2.36.5     v2.35.7 v2.34.7 v2.33.7 v2.32.6, v2.31.7 and v2.30.8. If upgrading is impractical, two short-term     workarounds are available. Avoid cloning repositories from untrusted sources with `--recurse-submodules`.
    Instead, consider cloning repositories without recursively cloning their submodules, and instead run `git     submodule update` at each layer. Before doing so, inspect each new `.gitmodules` file to ensure that it     does not contain suspicious module URLs. (CVE-2023-22490)

  - Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6,     2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to `git apply`, a     path outside the working tree can be overwritten as the user who is running `git apply`. A fix has been     prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6,     v2.31.7, and v2.30.8. As a workaround, use `git apply --stat` to inspect a patch before applying; avoid     applying one that creates a symbolic link and then creates a file beyond the symbolic link.
    (CVE-2023-23946)

  - In Git for Windows, the Windows port of Git, no localized messages are shipped with the installer. As a     consequence, Git is expected not to localize messages at all, and skips the gettext initialization.
    However, due to a change in MINGW-packages, the `gettext()` function's implicit initialization no longer     uses the runtime prefix but uses the hard-coded path `C:\mingw64\share\locale` to look for localized     messages. And since any authenticated user has the permission to create folders in `C:\` (and since     `C:\mingw64` does not typically exist), it is possible for low-privilege users to place fake messages in     that location where `git.exe` will pick them up in version 2.40.1. This vulnerability is relatively hard     to exploit and requires social engineering. For example, a legitimate message at the end of a clone could     be maliciously modified to ask the user to direct their web browser to a malicious website, and the user     might think that the message comes from Git and is legitimate. It does require local write access by the     attacker, though, which makes this attack vector less likely. Version 2.40.1 contains a patch for this     issue. Some workarounds are available. Do not work on a Windows machine with shared accounts, or     alternatively create a `C:\mingw64` folder and leave it empty. Users who have administrative rights may     remove the permission to create folders in `C:\`. (CVE-2023-25815)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - git: cvsserver command injection (CVE-2017-14867)

  - git: Heap overflow in `git archive`, `git log --format` leading to RCE (CVE-2022-41903)

  - Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of     service (memory consumption) via a crafted repository, aka a Git bomb.

(CVE-2017-15298)

  - git-shell in git before 2.4.12, 2.5.x before 2.5.6, 2.6.x before 2.6.7, 2.7.x before 2.7.5, 2.8.x before     2.8.5, 2.9.x before 2.9.4, 2.10.x before 2.10.3, 2.11.x before 2.11.2, and 2.12.x before 2.12.3 might     allow remote authenticated users to gain privileges via a repository name that starts with a - (dash)     character. (CVE-2017-8386)

  - GIT version 2.15.1 and earlier contains a Input Validation Error vulnerability in Client that can result     in problems including messing up terminal configuration to RCE. This attack appear to be exploitable via     The user must interact with a malicious git server, (or have their traffic modified in a MITM attack).
    (CVE-2018-1000021)

  - 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. The --export-marks option of git fast-import is exposed also via the in-     stream command feature export-marks=... and it allows overwriting arbitrary paths. (CVE-2019-1348)

  - Git is an open-source distributed revision control system. In affected versions of Git a specially crafted     repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may     cause just-checked out script to be executed while cloning onto a case-insensitive file system such as     NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS).

  - Git is distributed revision control system. gitattributes are a mechanism to allow defining attributes for     paths. These attributes can be defined by adding a `.gitattributes` file to the repository, which contains     a set of file patterns and the attributes that should be set for paths matching this pattern. When parsing     gitattributes, multiple integer overflows can occur when there is a huge number of path patterns, a huge     number of attributes for a single pattern, or when the declared attribute names are huge. These overflows     can be triggered via a crafted `.gitattributes` file that may be part of the commit history. Git silently     splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the     index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index     or both. This integer overflow can result in arbitrary heap reads and writes, which may result in remote     code execution. The problem has been patched in the versions published on 2023-01-17, going back to     v2.30.7. Users are advised to upgrade. There are no known workarounds for this issue. (CVE-2022-23521)

  - Git is an open source, scalable, distributed revision control system. `git shell` is a restricted login     shell that can be used to implement Git's push/pull functionality via SSH. In versions prior to 2.30.6,     2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4, the function that splits the command arguments     into an array improperly uses an `int` to represent the number of entries in the array, allowing a     malicious actor to intentionally overflow the return value, leading to arbitrary heap writes. Because the     resulting array is then passed to `execv()`, it is possible to leverage this attack to gain remote code     execution on a victim machine. Note that a victim must first allow access to `git shell` as a login shell     in order to be vulnerable to this attack. This problem is patched in versions 2.30.6, 2.31.5, 2.32.4,     2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 and users are advised to upgrade to the latest version.
    Disabling `git shell` access via remote logins is a viable short-term workaround. (CVE-2022-39260)
