Ldap Injection on Docker
How Ldap Injection Manifests in Docker
LDAP injection in Docker environments typically occurs when applications running inside containers construct LDAP queries using untrusted user input without proper sanitization. This vulnerability becomes particularly dangerous in containerized microservices architectures where authentication and authorization services are often separated into their own containers.
Consider a common Docker-based authentication service pattern where a Node.js application connects to an LDAP server to validate user credentials. The vulnerable code might look like this:
Docker-Specific Detection
Detecting LDAP injection in Docker environments requires both runtime monitoring and static analysis of container configurations. The most effective approach combines automated scanning with manual code review.
middleBrick's Docker-aware scanning can identify LDAP injection vulnerabilities by analyzing the runtime behavior of containers and their network interactions. When you scan a Docker-deployed API endpoint, middleBrick tests for LDAP injection patterns by:
- Analyzing the container's network exposure and LDAP service dependencies
- Testing LDAP query construction patterns with malicious payloads
- Monitoring for directory traversal or information disclosure through LDAP responses
- Checking for excessive resource consumption that might indicate injection attacks
Here's how you would use middleBrick to scan a Docker-deployed LDAP service:
