Summary

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.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
