CVE-2015-3960 is a vulnerability of currently unknown severity. The firmware in MNS before 4.5.6 on Belden GarrettCom Magnum 6K and Magnum 10K switches uses hardcoded RSA private keys and certificates across different customers' installations, which makes it easier for remote attackers to defeat cryptographic protection mechanisms for HTTPS sessions by leveraging knowledge of a private key from another installation.. EPSS estimates a 0.88% chance of exploitation in the next 30 days.
