high Nessus Plugin ID 14235
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 host has application that may allow arbitrary code execution on the remote system.


The version of Opera installed on the remote host is vulnerable to a flaw wherein a remote attacker can obscure the URI, leading the user to believe that he/she is accessing a trusted resource. To exploit this issue, an attacker would need to set up a rogue website, then entice a local user to visit the site. Successful exploitation would enable the attacker to execute arbitrary code on this host.


Install Opera 7.54 or newer.
