Description

If the device does not generate sufficiently random cryptographic primitives, a threat actor could predict or brute-force guess a key to either gain unauthorized access to the device or decrypt a connection. Cryptographic keys that are not generated with random “seed” information, including from Pseudo-Random Number Generators (PRNG), will lack sufficient entropy. For example, researchers have demonstrated that a large number of Internet exposed devices with TLS or SSH services utilized the same RSA moduli, which could be then used to determine the device’s private key and then used to remotely authenticate with the device.

CWE

CWE-331: Insufficient Entropy (Base)
CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) (Base)

CVE-2012-4898 (GCVE-0-2012-4898)

Vulnerability from cvelistv5 – Published: 2012-12-18 11:00 – Updated: 2025-07-09 16:22

Title

Tropos Wireless Mesh Routers Insufficient Entropy

Summary

Mesh OS before 7.9.1.1 on Tropos wireless mesh routers does not use a sufficient source of entropy for SSH keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere.

Severity

No CVSS data available.
