CVE-2025-24497
Published: 05 February 2025
Description
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Security Summary
CVE-2025-24497 is a denial-of-service vulnerability affecting the F5 BIG-IP Traffic Management Microkernel (TMM). When URL categorization is configured on a virtual server, certain undisclosed requests can cause TMM to terminate. The issue is linked to CWE-125 (Out-of-bounds Read) and 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), reflecting high availability impact with no confidentiality or integrity effects. Software versions that have reached End of Technical Support (EoTS) were not evaluated.
A remote, unauthenticated attacker can exploit this vulnerability by sending the undisclosed requests to an affected virtual server with URL categorization enabled. Successful exploitation leads to TMM termination, resulting in a denial of service that disrupts traffic processing on the BIG-IP system until TMM restarts.
The F5 security advisory at https://my.f5.com/manage/s/article/K000140920 provides details on mitigation, including available patches and configuration guidance.
