CVE-2025-24497 is a high-severity vulnerability affecting the F5 BIG-IP Policy Enforcement Manager. This vulnerability allows for the termination of the Traffic Management Microkernel (TMM) when URL categorization is configured on a virtual server, leading to potential service disruptions. The CVSS score for this vulnerability is 8.7, indicating a significant risk to systems utilizing the affected product.
Organizations using F5 BIG-IP Policy Enforcement Manager should be particularly vigilant, as the vulnerability has a high impact on availability. Requests that are not adequately disclosed can trigger this vulnerability, suggesting that attackers may exploit it to cause service interruptions. Given the potential for disruption, organizations should prioritize addressing this vulnerability.
Currently, there are no known public exploits or proofs of concept associated with this vulnerability, but the implications of an attack could be severe. It is critical for organizations to remain proactive in their security measures, especially in light of the high CVSS score.
Organizations should prioritize patching immediately to mitigate the risks associated with CVE-2025-24497. The urgency of this action is underscored by the potential for significant availability impacts on affected systems.
Vulnerability Details
The vulnerability occurs when URL categorization is configured on a virtual server, leading to termination of the TMM process. This issue specifically affects versions of F5 BIG-IP Policy Enforcement Manager from 17.1.0 to 17.1.1. The vulnerability is classified under CWE-125, indicating improper validation of input data.
The CVSS 4.0 base score of 8.7 reflects a high severity level, with an attack vector of NETWORK and low attack complexity. No privileges are required for exploitation, and no user interaction is necessary, making it particularly concerning for organizations.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of undisclosed requests when URL categorization is enabled. This misconfiguration could allow an attacker to exploit the vulnerability without any required privileges or user interaction.
The attack complexity is considered low, meaning that even less sophisticated attackers could potentially exploit this vulnerability. As a result, the availability impact is rated as high, posing a severe risk to organizations running affected systems.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions due to TMM termination, which could lead to downtime and loss of productivity. The blast radius of this vulnerability is significant, particularly for organizations relying on F5 BIG-IP to manage traffic efficiently.
Considering the high CVSS score and the potential for widespread impact, organizations should address this vulnerability in their priority patch cycle. The EPSS score of 0.0048 indicates a low probability of exploitation, but the potential consequences warrant immediate attention.
