Attack-Flow Graph

Executive Summary

This vulnerability is an OS command injection flaw in the oclif framework up to version 4.23.16. It exists in the child_process.exec function within the JIT Plugin Entry Handler component. An attacker with local access can manipulate the jitPlugins argument to execute arbitrary commands on the system.

Detection Guidance

This vulnerability is specific to the oclif framework up to version 4.23.16 and requires local access to exploit. Detection involves checking the installed version of oclif. Use the command: npm list oclif or oclif --version. If the version is 4.23.16 or lower, the system is vulnerable.

Impact Analysis

The impact includes potential unauthorized command execution on the affected system. Since local access is required, an attacker must already have some level of system access. This could lead to data theft, system compromise, or further lateral movement within a network.

Compliance Impact

This vulnerability allows local command injection via the jitPlugins argument in oclif up to 4.23.16. While it requires local access, successful exploitation could lead to unauthorized code execution, potentially compromising sensitive data handling. This may impact compliance with GDPR (data protection) and HIPAA (health data security) if exploited in systems processing regulated data.

Mitigation Strategies

Immediately update oclif to a patched version. Apply the patch referenced as 939b045725e065baebc4587b8bccfd56731eed3d. If updating is not possible, restrict local access to untrusted users and monitor for suspicious activity.
