CVE-2015-4259 is a vulnerability of currently unknown severity. The Integrated Management Controller on Cisco Unified Computing System (UCS) C servers with software 1.5(3) and 1.6(0.16) has a default SSL certificate, which makes it easier for man-in-the-middle attackers to bypass cryptographic protection mechanisms by leveraging knowledge of a private key, aka Bug IDs CSCum56133 and CSCum56177.. EPSS estimates a 0.78% chance of exploitation in the next 30 days.
