CRITICAL:
Less critical
IMPACT:
Spoofing
WHERE:
>From remote
SOFTWARE:
Opera 7.x
DESCRIPTION:
Secunia has discovered a vulnerability in the Opera browser, which
can be exploited by malicious people to fake (spoof) information
displayed in the address bar.
The vulnerability is caused due to the Opera browser changing
information in the address bar as soon as the browser is "asked" to
redirect to a new page. However, using e.g. the <BODY> tag attribute
"onUnload", it is possible to abort the redirection without the
address bar being changed back.
This can be exploited by a malicious website to trick users into
thinking that they're on another website.
The vulnerability has been confirmed in version 7.23 for Windows and
Linux. Prior versions may also be affected.
SOLUTION:
Update to version 7.50.
