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 a web browser installed that is vulnerable by multiple vulnerabilities


Versions of Opera earlier than 12.15 are potentially affected by the following vulnerabilities :

- A weakness exists in the RC4 encryption protocol, allowing an attacker to derive the plaintext. (1046)

- A weakness exists due to the application allowing cookies to be set for top-level domains, potentially exposing the cookie to the entire top-level domain. A malicious site could redirect the user to another website within the same top-level domain causing it to reuse its cookie. (1047)

- An unspecified, moderate severity issue exists that has an unspecified impact.


Upgrade to Opera 12.15 or later.
