Opera < 9.25 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 4323
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 remote host contains a web browser that is affected by several issues.

Description

The version of Opera installed on the remote host reportedly is affected by several issues :

- An issue where TLS certificates could be used to execute arbitrary code.

- The browser processes a 3xx HTTP CONNECT response before a successful SSL handshake, which could allow a man-in-the-middle attacker to execute arbitrary web script in the context of a HTTPS server.

Solution

Upgrade to version 9.25 or higher.
