CVE-2025-6712 in Server
Summary
by MITRE • 07/07/2025
MongoDB Server may be susceptible to disruption caused by high memory usage, potentially leading to server crash. This condition is linked to inefficiencies in memory management related to internal operations. In scenarios where certain internal processes persist longer than anticipated, memory consumption can increase, potentially impacting server stability and availability. This issue affects MongoDB Server v8.0 versions prior to 8.0.10

MongoDB Server version 8.0 prior to 8.0.10 contains a memory management vulnerability that can lead to server instability and potential crashes due to excessive memory consumption. This vulnerability stems from inefficiencies in how the database handles internal operations, particularly when certain processes remain active for extended periods beyond normal operational expectations. The flaw manifests when internal MongoDB mechanisms fail to properly release memory resources, causing progressive memory accumulation that can eventually overwhelm system resources and result in service disruption. This issue represents a significant concern for production environments where MongoDB servers handle substantial workloads and continuous operations. The vulnerability falls under the category of memory leak or resource exhaustion conditions that can severely impact system availability and reliability. According to CWE classification, this vulnerability aligns with CWE-401: Improper Release of Memory and CWE-772: Missing Release of Resource after Effective Lifetime, both of which describe failures in resource management that can lead to system instability. The operational impact extends beyond simple performance degradation to potential complete service outages, particularly in environments where memory constraints are already tight or where the database experiences high concurrency levels. Attackers or system administrators may exploit this vulnerability by triggering conditions that cause internal processes to persist longer than normal, leading to memory accumulation that eventually causes the server to crash or become unresponsive. The vulnerability is particularly concerning in cloud environments or containerized deployments where memory limits are strictly enforced and sudden resource exhaustion can trigger automatic termination of database processes. From an attack perspective, this vulnerability maps to ATT&CK technique T1499.004: Endpoint Denial of Service, specifically focusing on resource exhaustion attacks that target memory management within database systems. The issue affects MongoDB Server versions 8.0.0 through 8.0.9, making it critical for organizations running these versions to implement immediate mitigation strategies. The root cause involves internal MongoDB server mechanisms that fail to properly manage memory allocation and deallocation cycles for temporary data structures used during database operations. This can occur during complex query processing, aggregation operations, or when handling large datasets where internal temporary memory structures are not released promptly. Organizations should prioritize upgrading to MongoDB Server version 8.0.10 or later, which includes patches addressing the memory management inefficiencies. Additionally, implementing monitoring solutions that track memory consumption patterns can help detect early signs of this vulnerability. System administrators should also consider implementing resource limits and memory monitoring alerts to prevent complete service disruption. The vulnerability demonstrates the critical importance of proper resource management in database systems and highlights the need for thorough testing of memory allocation patterns under various workload conditions. Security teams should include this vulnerability in their risk assessment matrices, particularly for environments where MongoDB serves as a critical data store and where service availability is paramount for business operations.
