SunSSH < 1.1.1 / 1.3 CBC Plaintext Disclosure

critical Nessus Plugin ID 55992
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 SSH service running on the remote host has an information disclosure vulnerability.

Description

The version of SunSSH running on the remote host has an information disclosure vulnerability. A design flaw in the SSH specification could allow a man-in-the-middle attacker to recover up to 32 bits of plaintext from an SSH-protected connection in the standard configuration. An attacker could exploit this to gain access to sensitive information.

Note that this version of SunSSH is also prone to several additional issues but Nessus did not test for them.

Solution

Upgrade to SunSSH 1.1.1 / 1.3 or later
