CyberRota Analysis
AI-GeneratedThe blueprint resynthesis framework in Amazon Web Services CodeCatalyst prior to version 0.3.156 is vulnerable to command injection due to improper handling of shell metacharacters in the owner field of a .ownership-file. This flaw allows users with repository commit permissions to execute arbitrary commands, potentially compromising the integrity of the environment. Organizations utilizing this framework should prioritize upgrading to version 0.3.156 or later to mitigate the risk of exploitation.

Original NVD Description
Improper neutralization of special elements used in an OS command (CWE-78) in the blueprint resynthesis framework in Amazon Web Services codecatalyst-blueprints before 0.3.156 might allow a user with permission to commit to a repository in the project to execute arbitrary commands in the blueprint resynthesis environment via shell metacharacters in the owner field of a [local] merge strategy entry in a crafted .ownership-file. Version 0.3.156 removes shell interpretation of the owner field, running the command directly rather than through a shell, and rejects values outside an allowlisted command form. This eliminates shell metacharacter command injection. To remediate this issue, users should upgrade to version 0.3.156 or later. No action is required for use of the Amazon CodeCatalyst service. Resynthesis runs in an isolated per-project environment with scoped credentials, and the service applies server-side validation there that rejects [local] merge strategy commands outside a restricted allowlisted form, including for blueprint versions published before 0.3.156.
