cwe-400-resource-exhaustion

To remediate CWE-400 uncontrolled resource consumption in Java, enforce strict limits on uploads, collections, and external operations. Analyze controller, service, and repository layers to prevent unbounded memory growth and denial-of-service attacks.

Uncontrolled resource consumption vulnerabilities in Java code stem from unbounded resource growth patterns like loading large files into memory or expanding collections without limits. Attackers exploit these flaws to crash servers and trigger system instability.

Secure a Java file upload endpoint against denial-of-service by adding strict size limits and streaming large files directly to disk. This prevents attackers from exhausting server memory with massive upload payloads.

Yes, it remediates SAST findings for unbounded collection growth by analyzing Java controller, service, and repository layers. It applies secure implementations using streaming and timeouts to establish deterministic limits on external operations.

The best way to prevent memory exhaustion from large file uploads in Java is streaming files to disk instead of loading them into memory. Enforcing upload size limits provides a deterministic fix against uncontrolled resource consumption.
