Vulnerability Details
CVE-2025-24319 describes a vulnerability in the F5 BIG-IP Next Central Manager. When this system is active, undisclosed API requests can terminate the Kubernetes service. The vulnerability has a CVSS score of 7.1, placing it in the high severity category. This indicates that the impact on availability is significant, while confidentiality and integrity are not affected.
The affected product is F5's BIG-IP Next Central Manager, specifically versions from 20.2.0 to below 20.3.0. This vulnerability is classified under CWE-20, which relates to improper input validation.
Technical Analysis
The root cause of this vulnerability stems from the handling of API requests within the BIG-IP Next Central Manager. Insufficient validation of input can lead to unauthorized requests being processed, resulting in the termination of critical services. The attack vector is network-based, indicating that an attacker can exploit this vulnerability remotely without needing direct access to the system.
The attack complexity is considered low, as minimal technical skills are required to exploit this vulnerability. Privileges required for exploitation are low, meaning an attacker could potentially execute this attack with minimal access rights. There is no user interaction required for the exploitation to occur.
The vulnerability impacts availability significantly, as it can lead to service disruptions. However, confidentiality and integrity impacts are classified as none, which suggests that sensitive data is not at risk due to this vulnerability.
Risk & Impact Analysis
Organizations using F5 BIG-IP Next Central Manager must understand the real-world risk posed by this vulnerability. The ability for unauthorized API requests to terminate Kubernetes services creates a significant potential for operational challenges. The blast radius could extend to all services reliant on the affected Kubernetes nodes, leading to widespread service disruption.
Given the high CVSS score, organizations should treat this vulnerability with urgency. The risk of service interruption necessitates immediate patching and remediation. As this vulnerability does not currently have known exploits, organizations still must implement defensive measures to mitigate future threats.
