CVE-2025-20058 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in F5 Big-Ip Access Policy Manager. Its CVSS base score is 8.9 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique OS Exhaustion Flood (T1499.001); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-20058 is a denial-of-service vulnerability in F5 BIG-IP systems, specifically affecting configurations where a message routing profile is enabled on a virtual server. Undisclosed traffic directed at such a virtual server can trigger excessive memory resource utilization, classified under CWE-400 (Uncontrolled Resource Consumption). The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its potential for availability disruption without requiring authentication or user interaction. Only BIG-IP software versions still under technical support are evaluated for impact.
A remote, unauthenticated attacker can exploit this vulnerability by sending crafted traffic to the affected virtual server. Successful exploitation leads to increased memory consumption on the BIG-IP system, potentially resulting in resource exhaustion and denial-of-service conditions that impair the device's functionality and traffic processing capabilities.
F5 has published an advisory detailing the issue and mitigation strategies at https://my.f5.com/manage/s/article/K000140947. Security practitioners should consult this reference for specific affected versions, patch availability, and recommended configuration changes. Note that software versions at End of Technical Support (EoTS) are not evaluated.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SC-5 directly limits the effects of resource-exhaustion events that constitute uncontrolled consumption.
SC-6 enforces explicit allocation limits on resources, structurally preventing the weakness from occurring.
Process isolation confines resource consumption to separate domains, reducing blast radius without stopping the root flaw.

Explicitly requires monitoring and maintaining resource capacity, directly addressing uncontrolled consumption to preserve availability.
Continuous monitoring of computing resources can detect resource exhaustion but does not itself enforce allocation limits.
Resilience mechanisms such as avoiding single points of failure indirectly reduce impact of resource exhaustion.
Hardened configuration baselines can include resource quotas and limits that constrain consumption.

Resource-utilization monitoring and alerting on bottlenecks or overloads limits the impact of denial-of-service or resource-exhaustion attacks.
By continuously monitoring utilization, stress-testing peak loads, and maintaining documented plans to scale or throttle resources, the control directly limits an attacker’s ability to drive a system into uncontrolled resource exhaustion.
Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.
Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.
Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.
Early notification of anomalous resource consumption or system malfunctions enables throttling or isolation before availability is lost.
