Improper Resource Management
Overview
Improper resource management refers to the failure to correctly allocate, use, and release system resources such as memory, file handles, or network connections. This weakness arises when software does not adequately control resource lifecycles, leading to resource leaks, exhaustion, or corruption.
Why It Matters
- Security impact: Can lead to denial of service, system instability, or unauthorized access through resource exhaustion or corruption.
- Business risk: Causes downtime, degraded performance, and increased maintenance costs, potentially affecting customer trust and revenue.
- Common consequences: Application crashes, degraded system performance, and vulnerability to exploitation by attackers.
Where It Appears
- Environments: Found in both client and server environments, including embedded systems and cloud infrastructures.
- Systems or processes: Occurs in software applications, operating systems, and network services managing resources like memory, CPU, and file descriptors.
- Typical conditions: Arises under high load, prolonged operation, or when error handling fails to properly release resources.
How It Is Exploited (High Level)
Attackers exploit improper resource management by triggering resource leaks or exhaustion, causing denial of service or enabling further attacks through system instability or predictable resource states.
How It Is Addressed (High Level)
Mitigation involves implementing proper resource allocation and deallocation practices, enforcing limits on resource usage, and incorporating robust error handling and monitoring to detect and recover from resource-related issues.
