Categoría:	F5 Local Security Checks
Título:	F5 BIG-IP - SLOTH: TLS 1.2 handshake vulnerability CVE-2015-7575
Resumen:	The remote host is missing a security patch.
Descripción:	Summary: The remote host is missing a security patch. Vulnerability Insight: A flaw was found in the way TLS 1.2 uses RSA+MD5 signatures with Client Authentication and ServerKeyExchange messages during a TLS 1.2 handshakes. An attacker with a Man-in-the-Middle network position and the ability to force / observe the use of RSA+MD5 during a TLS Handshake, may be able to successfully generate a hash collision and impersonate a TLS client or server. The vulnerability of CVE-2015-7575 is relevant to cryptography software which supports TLS 1.2 only as earlier versions of TLS used different hash functionality in those protocols. Solution: See the referenced vendor advisory for a solution. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
