Data plane is vulnerable when using the MPTCP option of a TCP profile. There is no control plane exposure. An attacker may be able to disrupt services by causing TMM to restart hence temporarily failing to process traffic.","published":"2017-10-27T14:29:00.000Z","lastModified":"2026-06-17T01:21:52.000Z","status":"Modified","sourceIdentifier":"f5sirt@f5.com","cvss":{"version":"3.0","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["f5/big-ip local traffic manager","f5/big-ip application acceleration manager","f5/big-ip advanced firewall manager","f5/big-ip access policy manager","f5/big-ip application security manager","f5/big-ip link controller","f5/big-ip policy enforcement manager","f5/big-ip websafe"],"epss":{"score":0.01589,"percentile":0.7551,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (1.59%).
