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.

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

  - 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)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3145 advisory.

  - 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)

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

An update of the git package has been released.

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5076-1 advisory.

    It was discovered that Git allowed newline characters in certain repository paths. An attacker could     potentially use this issue to perform cross-protocol requests.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
