How to Fix CVE-2022-21235

To remediate this vulnerability, upgrade all affected Github.com/Masterminds/vcs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/Masterminds/vcs fixed: 1.13.2 
Upgrade github.com/Masterminds/vcs to 1.13.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/Masterminds/vcs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-21235, inspect your project dependencies for Github.com/Masterminds/vcs:

inspect dependencies for github.com/Masterminds/vcs

Analyze the terminal output to locate any version of Github.com/Masterminds/vcs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In Github.com/Masterminds/vcs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

URLs and local file paths passed to the Mercurial (hg) APIs that are specially crafted can contain commands which are executed by Mercurial if it is installed on the host operating system. The `vcs` package uses the underly version control system, in this case `hg`, to implement the needed functionality. When `hg` is executed, argument strings are passed to `hg` in a way that additional flags can be set. The additional flags can be used to perform a command injection. Other version control systems with an implemented interface may also be vulnerable. The issue has been fixed in version 1.13.2. A work around is to sanitize data passed to the `vcs` package APIs to ensure it does not contain commands or unexpected data. This is important for user input data that is passed directly to the package APIs.
