New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 4.9

Synopsis

The remote host allows the resumption of SSL sessions with a disabled cipher.

Description

The version of OpenSSL on the remote host has been shown to allow the use of disabled ciphers when resuming a session. This means that an attacker that sees (e.g. by sniffing) the start of an SSL connection can manipulate the OpenSSL session cache to cause subsequent resumptions of that session to use a disabled cipher chosen by the attacker.

Solution

Upgrade to OpenSSL 0.9.8j or later.
