CVE Catalog

CVE-2017-5243

High
Published: Translated: NVD NIST

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, making installations vulnerable to a range of MITM, downgrade, and decryption attacks.

Risk Assessment

The lack of proper SSH configuration increases the risk of attacks that could lead to data interception or unauthorized access to systems.

Recommendation

It is recommended to update the SSH configuration to specify particular algorithms for key exchange and other functions, which will minimize the risk of attacks.
