Box

Security checks for vulnerabilities and agentic risk

Overview

Box operations have clear approval safeguards, but setup can execute unverified remote code and introduce broader agent changes without clear user control.

Review setup before enabling this skill. Install a verified CLI release separately and check its automatic skill synchronization settings; the documented OO_SKILLS_SYNC_DISABLED control disables that synchronization. OOMOL will mediate Box access and downloaded content. Keep the existing write and deletion confirmations. The installer contents could not be inspected, so their exact local changes remain uncertain.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk performs no visible Box operations and instead executes an installer from a non-Box domain. Although dependency installation can be a supporting implementation detail, this chunk establishes no connection between the Oomol installer and the declared Box functionality. The downloaded script's contents are not supplied, so its further behavior cannot be assessed.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into bash executes mutable remote content without verifying an expected release or reviewing the script. HTTPS protects transport but does not prevent a compromised distribution service from supplying malicious code, which could access local files or credentials under the current user's permissions.

The fallback setup instructs execution of remote installation scripts without warning about the system-integrity risk.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without an integrity check or explicit approval for local software installation. A compromised distribution endpoint could execute arbitrary code with the invoking user's privileges; the missing-CLI condition limits exposure but does not make the installation safe.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
