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.


The remote security appliance is missing a vendor-supplied patch.


According to its self-reported version, the version of AsyncOS running on the remote Cisco Content Security Management Appliance (SMA) is affected by a remote code execution vulnerability due to a buffer overflow condition in the telnet component.


Apply the relevant update referenced in Cisco Security Advisory cisco-sa-20120126-ironport.

Alternatively, as a workaround, the vendor notes that Telnet services can be disabled on the device.
