New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 2.7
Synopsis
The remote host contains a web browser that is affected by multiple vulnerabilities.
Description
The version of Opera installed on the remote Windows host is prior to 11.51. It is, therefore, affected by multiple vulnerabilities :
- An unspecified error can allow an insecure or malicious site to cause the browser to display security information belonging to another, secure site in the address bar. This causes the insecure or malicious site to appear to be part of, or secured by, a third-party site. (CVE-2011-3388)
- An information disclosure vulnerability, known as BEAST, exists in the SSL 3.0 and TLS 1.0 protocols due to a flaw in the way the initialization vector (IV) is selected when operating in cipher-block chaining (CBC) modes. A man-in-the-middle attacker can exploit this to obtain plaintext HTTP header data, by using a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses the HTML5 WebSocket API, the Java URLConnection API, or the Silverlight WebClient API. (CVE-2011-3389)
Solution
Upgrade to Opera 11.51 or later.
