CVE-2015-8240: The Traffic Management Microkernel (TMM) in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Control...

The Traffic Management Microkernel (TMM) in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Controller, and BIG-IP PEM before 11.4.1 HF10, 11.5.x before 11.5.4, and 11.6.x before 11.6.0 HF6 and BIG-IP PSM before 11.4.1 HF10 does not properly handle TCP options, which allows remote attackers to cause a denial of service via unspecified vectors, related to the tm.minpathmtu database variable.

Security readout for executives and security teams

This is a denial-of-service flaw in F5 BIG-IP’s traffic processing engine. A remote attacker could make affected BIG-IP systems disrupt service by triggering improper handling of TCP options. The sources do not show data theft, code execution, CVSS scoring, or confirmed active exploitation. Exposure is most relevant where affected F5 BIG-IP systems process network traffic for public or critical applications. The source bundle names multiple BIG-IP modules, but does not provide CPE detail, deployment conditions, or precise attack prerequisites. Prioritize remediation for BIG-IP devices supporting customer-facing or mission-critical applications. The main business risk is service outage, not confirmed compromise, and current evidence does not support an active-exploitation claim. Mitigation focus: Identify BIG-IP products and software branches in use.; Upgrade to the fixed F5 versions or hotfixes listed for the affected branch.; Review the F5 advisory before changing tm.minpathmtu or related operational settings..
