IT Glue

Security checks for vulnerabilities and agentic risk

Overview

The IT Glue workflow is coherent, but its setup fallback runs downloaded code without clear approval or limits on lasting local changes.

Review the setup behavior before enabling this skill. Prefer a separately approved, reviewed CLI installation and retain control over additional agent-skill changes. Only connect IT Glue if you trust OOMOL to handle the connection and returned records. The bundled instructions were fully inspected, but the remote installers and connector implementation remain unverified; no malicious behavior was established.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command runs an Oomol installer and shows no IT Glue access or data retrieval. Nothing in the supplied content establishes this installation as a supporting dependency for the declared purpose. The downloaded script's further behavior cannot be determined from this code chunk.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping a remote installation script directly into Bash executes mutable network-supplied code without version pinning or independent integrity verification; the PowerShell alternative has the same weakness. HTTPS and the provider's legitimate role reduce some risks but do not protect against a compromised distribution endpoint or malicious installer update, which could access local data with the agent's privileges.

Fallback setup executes downloaded installation scripts without warning the user about local system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The missing-CLI fallback directs the agent to execute downloaded installation code without first obtaining approval for local software installation. Although conditional and relevant to setup, it expands a read-oriented IT Glue request into local code execution and system changes with the agent's permissions.

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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
