CVE-2015-3960: Garrettcom Magnum 10k Firmware

Medium severity, CVSS 4.3. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Garrettcom Magnum 10k Firmware: up to and including 4.5.5
• Garrettcom Magnum 6k Firmware: up to and including 4.5.5
