Insecure Inter-Process Communication
Overview
Insecure Inter-Process Communication (IPC) refers to vulnerabilities that arise when processes exchange data without adequate security controls, such as authentication, authorization, or encryption. This weakness occurs when communication channels between processes are exposed or improperly protected, allowing unauthorized access or manipulation of data.
Why It Matters
- Security impact: Can lead to unauthorized data access, privilege escalation, or code injection between processes.
- Business risk: May result in data breaches, service disruption, or loss of customer trust.
- Common consequences: Information leakage, unauthorized command execution, or system compromise.
Where It Appears
- Environments: Operating systems, distributed systems, and mobile platforms.
- Systems or processes: Applications that rely on shared memory, sockets, pipes, or messaging queues for communication.
- Typical conditions: Lack of proper access controls, unencrypted channels, or insufficient validation of messages.
How It Is Exploited (High Level)
Attackers exploit insecure IPC by intercepting, injecting, or manipulating messages exchanged between processes to gain unauthorized access, escalate privileges, or disrupt normal operation.
How It Is Addressed (High Level)
Mitigation involves implementing strong authentication and authorization mechanisms, encrypting communication channels, validating input data rigorously, and applying the principle of least privilege to processes.
