| Detailed Description |
The Opera Web browser, according to its version number, has a file download extension spoofing vulnerability. Opera is a Web browser, developed by Opera Software, for multiple operating systems. Opera versions prior to 7.50 could allow a remote attacker to trick a user into running arbitrary code. This vulnerability involves specifying the CLSID for HTML applications in the name of a malicious file, followed by another file name and extension. The issue is triggered when a malicious web site provides a file for download, but crafts the filename in such a way that the file is executed, rather than saved.
A remote attacker could construct a hostile Web site that contains a malicious script exploiting this vulnerability, which would be executed in the victim's Web browser within the security context of the hosting site, once the malicious link is clicked.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
