Advisories for Npm/Simple-Git package

The blockUnsafeOperationsPlugin in simple-git fails to block git protocol override arguments when the config key is passed in uppercase or mixed case. An attacker who controls arguments passed to git operations can enable the ext:: protocol by passing -c PROTOCOL.ALLOW=always, which executes an arbitrary OS command on the host machine. | # | Vector | Payload | Sentinel file | Result | |—|——–|———|—————|——–| | 1 | CVE-2022-25912 original | protocol.ext.allow=always …

Versions of the package simple-git before 3.16.0 are vulnerable to Remote Code Execution (RCE) via the clone(), pull(), push() and listRemote() methods, due to improper input sanitization. This vulnerability exists due to an incomplete fix of CVE-2022-25912.

The package simple-git before 3.15.0 is vulnerable to Remote Code Execution (RCE) when enabling the ext transport protocol, which makes it exploitable via clone() method. This vulnerability exists due to an incomplete fix of CVE-2022-24066.

The package simple-git before 3.5.0 is vulnerable to Command Injection due to an incomplete fix of CVE-2022-24433 which only patches against the git fetch attack vector. A similar use of the –upload-pack feature of git is also supported for git clone, which the prior fix didn't cover.

The package simple-git before 3.3.0 is vulnerable to Command Injection via argument injection. When calling the .fetch(remote, branch, handlerFn) function, both the remote and branch parameters are passed to the git fetch subcommand. By injecting some git options it was possible to get arbitrary command execution.
