CVE-2012-3039: Moxa Oncell Gateway Firmware

High severity, CVSS 7.1. EPSS: 1.4% chance of exploitation in the next 30 days.

Moxa OnCell Gateway G3111, G3151, G3211, and G3251 devices with firmware before 1.4 do not use a sufficient source of entropy for SSH and SSL keys, which makes it easier for remote attackers to obtain access by leveraging knowledge of a key from a product installation elsewhere.

Affected products

• Moxa Oncell Gateway Firmware: up to and including 1.3
• Moxa Oncell Gateway g3111
• Moxa Oncell Gateway g3151
• Moxa Oncell Gateway g3211
• Moxa Oncell Gateway g3251
