Last modified

CVE-2015-6418 is a vulnerability of currently unknown severity. The random-number generator on Cisco Small Business RV routers 4.x and SA500 security appliances 2.2.07 does not have sufficient entropy, which makes it easier for remote attackers to determine a TLS key pair via unspecified computations upon handshake key-exchange data, aka Bug ID CSCus15224.. EPSS estimates a 1.84% chance of exploitation in the next 30 days.
