## Verdict summary
**Blocked & quarantined** — Unauthorized access, license modification, and remote appliance code execution are possible against reachable systems that accept the attempted credentials.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.7.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

When invoked through MCP, the package can attempt appliance logins against a caller-selected host without TLS verification, forge a license token, and change appliance settings. Its remote command path can also overwrite an appliance CLI script with supplied content using sudo.

## Security analysis

### Published attack-surface review

- **Summary:** When invoked through MCP, the package can attempt appliance logins against a caller-selected host without TLS verification, forge a license token, and change appliance settings. Its remote command path can also overwrite an appliance CLI script with supplied content using sudo.

- **Trigger:** An MCP client invokes the license or appliance command tools with a target host and arguments.

- **Impact:** Unauthorized access, license modification, and remote appliance code execution are possible against reachable systems that accept the attempted credentials.

- **Evidence paths:** dist/src/tools/license-tools.js, dist/src/utils/license.js, dist/src/appliance/commands.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T11:26:27.212Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Credential-candidate login, forged license issuance, and privileged remote script replacement.

- **Attack narrative:** The MCP server accepts a caller-selected appliance address, suppresses TLS certificate checks, and tries multiple credential candidates. On success it can create a signed license token using a built-in fallback signer and write it to the appliance settings API. Separately, its privileged SSH command builder accepts supplied script content and constructs a command that writes it with sudo to the appliance CLI path. These are concrete unauthorized-access and remote-control capabilities, not passive administration helpers.

- **Rationale:** Although no install-time hook runs, the published MCP tools expose an active chain for credential attempts, license forgery, and privileged remote modification of arbitrary caller-selected appliances. The absence of target allowlisting and TLS verification makes the capability concrete and unsafe.

- **Files touched:** /api/session, /api/org/:id/settings, /home/calltelemetry/cli.sh

### Review decision

- **Verdict:** Malicious

- **Confidence:** 95.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The license tool disables TLS certificate verification for all appliance requests., An MCP call can target an arbitrary host and submit a sequence of configured or embedded administrator credential candidates to its session endpoint., The package mints license JWTs using a package-supplied default signer when no environment signer is present, then writes the token to the target appliance., The remote appliance command tool accepts supplied script content, writes it with sudo to a selected path, and makes it executable.

- **Evidence against:** The manifest has no preinstall, install, or postinstall hook; package installation alone does not trigger these actions., The risky actions require an MCP tool invocation rather than occurring during import or installation.

## Affected versions and remediation

This report applies to @calltelemetry/ct-lab-mcp@0.7.1.

- Avoid installing @calltelemetry/ct-lab-mcp@0.7.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
