Summary

aws-cdk-lib: OS Command Injection in NodejsFunction Docker Bundling

Details

Summary

AWS CDK (aws-cdk-lib) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. OS command injection issue in the NodejsFunction Docker bundling pipeline in aws-cdk-lib before 2.260.0 that might allow an actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed during Docker-based bundling with nodeModules specified.

Impact

During Docker-based Lambda bundling, when the nodeModules option is specified, NodejsFunction assembled a shell command string, including file-operation commands generated by an internal OsCommand helper, from the version strings of the modules listed in nodeModules, and executed it via a shell (bash -c) inside the bundling container. These version strings were interpolated without shell escaping, so values containing shell metacharacters could execute arbitrary commands inside the bundling container - which has read/write bind mounts to the host filesystem - with the privileges of the user running cdk synth, cdk deploy, or cdk diff. Leveraging this issue requires an actor to control a dependency version string for one of the listed modules - for example via an untrusted npm package referenced through nodeModules.

Impacted versions:

< 2.260.0

Patches

This issue has been addressed in aws-cdk-lib version 2.260.0 (PR #38133). We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds

Ensure that the modules listed in the nodeModules bundling option - and the version strings declared for them in your project's package.json, as well as the versions of the corresponding installed packages - come only from trusted sources, and audit third-party constructs and dependencies that introduce them. Using local bundling instead of Docker-based bundling avoids the affected code path. Upgrading to a fixed version is the recommended remediation.

Title

OS Command Injection in aws-cdk-lib Docker Bundling

Summary

OS command injection in the NodejsFunction Docker bundling pipeline (OsCommand helper) in AWS aws-cdk-lib on all platforms might allow a actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed during Docker-based bundling with nodeModules specified. To remediate this issue, users should upgrade to v2.260.0.
