CVE-2024-35183 Information
Description
wolfictl is a command line tool for working with Wolfi. A git authentication issue in versions prior to 0.16.10 allows a local user’s GitHub token to be sent to remote servers other than github.com. Most git-dependent functionality in wolfictl relies on its own git package which contains centralized logic for implementing interactions with git repositories. Some of this functionality requires authentication in order to access private repositories. A central function GetGitAuth looks for a GitHub token in the environment variable GITHUB_TOKEN and returns it as an HTTP basic auth object to be used with the github.com/go-git/go-git/v5 library. Most callers (direct or indirect) of GetGitAuth use the token to authenticate to github.com only; however in some cases callers were passing this authentication without checking that the remote git repository was hosted on github.com. This behavior has existed in one form or another since commit 0d06e1578300327c212dda26a5ab31d09352b9d0 - committed January 25 2023. This impacts anyone who ran the wolfictl check update commands with a Melange configuration that included a git-checkout directive step that referenced a git repository not hosted on github.com. This also impacts anyone who ran wolfictl update <url> with a remote URL outside of github.com. Additionally these subcommands must have run with the GITHUB_TOKEN environment variable set to a valid GitHub token. Users should upgrade to version 0.16.10 to receive a patch.

wolfictl
is
a
command
line
tool
for
working
with
Wolfi.
A
git
authentication
issue
in
versions
prior
to
0.16.10
allows
a
local
user’s
GitHub
token
to
be
sent
to
remote
servers
other
than
github.com.
Most
git-dependent
functionality
in
wolfictl
relies
on
its
own
git
package
which
contains
centralized
logic
for
implementing
interactions
with
git
repositories.
Some
of
this
functionality
requires
authentication
in
order
to
access
private
repositories.
A
central
function
GetGitAuth
looks
for
a
GitHub
token
in
the
environment
variable
GITHUB_TOKEN
and
returns
it
as
an
HTTP
basic
auth
object
to
be
used
with
the
github.com/go-git/go-git/v5
library.
Most
callers
(direct
or
indirect)
of
GetGitAuth
use
the
token
to
authenticate
to
github.com
only;
however
in
some
cases
callers
were
passing
this
authentication
without
checking
that
the
remote
git
repository
was
hosted
on
github.com.
This
behavior
has
existed
in
one
form
or
another
since
commit
0d06e1578300327c212dda26a5ab31d09352b9d0
committed
January
25
2023.
This
impacts
anyone
who
ran
the
wolfictl check update
commands
with
a
Melange
configuration
that
included
a
git-checkout
directive
step
that
referenced
a
git
repository
not
hosted
on
github.com.
This
also
impacts
anyone
who
ran
wolfictl update <url>
with
a
remote
URL
outside
of
github.com.
Additionally
these
subcommands
must
have
run
with
the
GITHUB_TOKEN
environment
variable
set
to
a
valid
GitHub
token.
Users
should
upgrade
to
version
0.16.10
to
receive
a
patch.
