Connections may be left in the connection table which then can only be removed by restarting TMM. Over time this may lead to the BIG-IP being unable to process further connections.","published":"2017-10-27T14:29:00.000Z","lastModified":"2026-06-17T00:57:28.000Z","status":"Modified","sourceIdentifier":"f5sirt@f5.com","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-459"],"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":0.02664,"percentile":0.85641,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (2.66%).
