CVE-2017-5243

TITLE

Rapid7 Nexpose Vulnerabilities in the use of cryptographic algorithms

Trust: 0.8

sources: JVNDB: JVNDB-2017-004681

DESCRIPTION

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. Rapid7 Nexpose Contains a vulnerability in the use of cryptographic algorithms.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Rapid7Nexposehardwareappliances is a hardware device with Nexpose from Rapid7 in the United States. Nexpose is a vulnerability management software that can comprehensively utilize different scan results for deep probing networks. A man-in-the-middle attack vulnerability exists in the default SSH configuration in the Rapid7Nexpose hardware device. An attacker can exploit this vulnerability to perform man-in-the-middle attacks, downgrade attacks, and decryption attacks
