Last modified

CVE-2018-15317 is a vulnerability of currently unknown severity. In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.5, 12.1.0-12.1.4.1, and 11.2.1-11.6.3.2, an attacker sending specially crafted SSL records to a SSL Virtual Server will cause corruption in the SSL data structures leading to intermittent decrypt BAD_RECORD_MAC errors. Clients will be unable to access the application load balanced by a virtual server with an SSL profile until tmm is restarted.. EPSS estimates a 1.36% chance of exploitation in the next 30 days.
