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.
