Opera < 11.60 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 6105


The remote host has a web browser installed that is vulnerable to multiple attack vectors.


The remote host is running the Opera web browser.

Versions of Opera earlier than 11.60 are potentially affected by multiple vulnerabilities :

- Top level domain separation rules are not honored for two-letter top level domains, e.g., .us or .uk and some three-letter top-level domains. This error can allow sites to set the scripting context to the top level domain. Further, this can allow sites to set and read cookies from other sites whose scripting context is set to the same top level domain. (Issue 1003)

- An error exists in the SSLv3 and TLSv1.3 specification that can allow the BEAST attack. (Issue 1004)

- An error exists in the implementation of the JavaScript 'in' operator that can allow sites to verify the existence of variables of sites in other domains. (Issue 1005)

- An unspecified, moderately sever issue exists. Details are to be disclosed by the vendor at a later date.


Upgrade to Opera 11.60 or later.
