Protocol Vulnerabilities

Exploiting flaws in MCP protocol implementation and communication, targeting the fundamental communication mechanisms of MCP systems.

Overview

Protocol vulnerabilities exploit weaknesses in the MCP protocol specification, implementation, or communication mechanisms to compromise system security.

Attack Techniques

Session IDs in URLs

Exposure of sensitive session identifiers in URL parameters, violating security best practices.

Lack of Authentication Standards

Absence of standardized authentication mechanisms in MCP protocol specification.

Missing Integrity Controls

Lack of message signing or verification mechanisms allowing message tampering.

Protocol Implementation Flaws

Bugs and vulnerabilities in MCP protocol implementations.

Insecure Communication

Unencrypted or poorly secured communication channels between MCP components.

Impact Assessment

  • Severity: Medium to High
  • Likelihood: Medium
  • Detection Difficulty: Medium

Common Indicators

  • Unencrypted protocol communications
  • Missing authentication mechanisms
  • Protocol implementation errors
  • Insecure session handling
  • Message integrity failures

General Mitigation Strategies

  1. Protocol Security: Implement secure protocol mechanisms
  2. Authentication: Deploy standardized authentication
  3. Integrity Protection: Implement message integrity controls
  4. Encryption: Use encrypted communications
  5. Implementation Security: Secure protocol implementations

Detection Methods

  • Protocol traffic analysis
  • Implementation testing
  • Security scanning
  • Communication monitoring

This category contains 5 distinct attack techniques focused on MCP protocol and communication vulnerabilities.
