Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. The vulnerability allows an attacker with a specially-crafted network service of a scan target to store an XSS sequence in the Metasploit Pro console, which will trigger when the operator views the record of that scanned host in the Metasploit Pro interface.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation
Update to version 4.17.1.
