Synopsis :

The remote host contains a web browser that is affected by 
multiple flaws.

Description :

The remote host is using Opera, an alternative web browser.

This version of Opera on the remote host fails to block write access to
the 'location' object.  This could allow a user to create a specially
crafted URL to overwrite methods within the 'location' object that would
execute arbitrary code in a user's browser within the trust relationship
between the browser and the server, leading to a loss of confidentiality
and integrity.

Risk factor : 

Medium / CVSS Base Score : 5
