CVE-2017-5243 (GCVE-0-2017-5243)

Vulnerability from cvelistv5 – Published: 2017-06-06 16:00 – Updated: 2024-08-05 14:55

Summary

The default SSH configuration in Rapid7 Nexpose hardware appliances shipped before June 2017 does not specify desired algorithms for key exchange and other important functions. As a result, it falls back to allowing ALL algorithms supported by the relevant version of OpenSSH and makes the installations vulnerable to a range of MITM, downgrade, and decryption attacks.

Severity

No CVSS data available.

CWE
