Opera < 7.55.0 Cross-Domain Dialog Box Spoofing

Low Nessus Network Monitor Plugin ID 2373


The remote host is vulnerable to a Cross-Site Scripting (XSS) attack.


The remote host is using a version of Opera that is prone to a security flaw where a malicious website can spoof a cross-domain dialog box that may entice the local user to enter information based on the bogus domain. For example, if the malicious website were to spoof a trusted domain, the user may enter confidential information into the dialog box. These sort of exploits are commonly referred to as 'Phishing' scams.


Install Opera 7.55.0 or higher.
