Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.5


The remote host has application that may allow arbitrary code execution on the remote system.


The version of Opera installed on the remote host is vulnerable to a flaw wherein a remote attacker can obscure the URI, leading the user to believe that he/she is accessing a trusted resource. To exploit this issue, an attacker would need to set up a rogue website, then entice a local user to visit the site. Successful exploitation would enable the attacker to execute arbitrary code on this host.


Install Opera 7.54 or newer.
