New! Plugin Severity Now Using CVSS v3

The remote host is running an obsolete operating system.


According to its version, the ScreenOS operating system on the remote host is obsolete and is no longer supported.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.
