The version of git installed on the remote host is prior to 2.18.4-2.71. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1413 advisory.

    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 toCVE-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. (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. 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.
