Synopsis
The remote Windows host has VPN client software installed that is affected by multiple vulnerabilities.Description
The remote Windows host is missing KB3062760, which resolves multiple OpenSSL vulnerabilities in the Juniper Networks Windows In-Box Junos Pulse client shipped with Windows 8.1 :- A flaw exists with ECDH handshakes when using an ECDSA certificate without a ServerKeyExchange message. This allows a remote attacker to trigger a loss of forward secrecy from the ciphersuite. (CVE-2014-3572)
- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)
- A flaw exists when accepting DH certificates for client authentication without the CertificateVerify message.
This allows a remote attacker to authenticate to the service without a private key. (CVE-2015-0205)
