Description
Glob matches files using patterns the shell uses. Starting in version 10.2.0 and prior to versions 10.5.0 and 11.1.0, the glob CLI contains a command injection vulnerability in its -c/--cmd option that allows arbitrary command execution when processing files with malicious names. When glob -c <command> <patterns> are used, matched filenames are passed to a shell with shell: true, enabling shell metacharacters in filenames to trigger command injection and achieve arbitrary code execution under the user or CI account privileges. This issue has been patched in versions 10.5.0 and 11.1.0.

Executive Summary

This vulnerability exists in the glob CLI tool versions 10.3.7 to 11.0.3. It involves the -c/--cmd option, which allows arbitrary command execution when processing files with malicious names. Specifically, when using glob -c <command> <patterns>, matched filenames are passed to a shell with shell: true. This means that shell metacharacters in filenames can trigger command injection, allowing an attacker to execute arbitrary code with the privileges of the user or CI account running the command. The issue was fixed in version 11.1.0.

Impact Analysis

This vulnerability can lead to arbitrary code execution on the affected system under the privileges of the user or CI account running the glob command. An attacker could exploit maliciously named files to execute commands, potentially leading to data compromise, system manipulation, or disruption of services. Because the CVSS score is 7.5 with high impact on confidentiality, integrity, and availability, the impact can be severe.

Mitigation Strategies

Upgrade the glob CLI to version 11.1.0 or later, as this version contains the patch that fixes the command injection vulnerability in the -c/--cmd option.
