New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote service may be affected by multiple vulnerabilities.

Description

According to its banner, the remote web server is running a version of OpenSSL 1.0.1 prior to 1.0.1f. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :

- An error exists in the 'ssl3_take_mac' function in the file 'ssl/s3_both.c' related to handling TLS handshake traffic that could lead to denial of service attacks.
(CVE-2013-4353)

- An error exists in the 'ssl_get_algorithm2' function in the file 'ssl/s3_lib.c' related to handling TLS 1.2 traffic that could lead to denial of service attacks.
(CVE-2013-6449)

- An error exists related to man-in-the-middle attackers and handling DTLS processes that could lead to various security bypasses. (CVE-2013-6450)

Solution

Upgrade to OpenSSL 1.0.1f or later.
