CVE-2023-0599: RAPID7 Metasploit

Medium severity, CVSS 4.8. EPSS: 0.4% chance of exploitation in the next 30 days.

Rapid7 Metasploit Pro versions 4.21.2 and lower suffer from a stored cross site scripting vulnerability, due to a lack of JavaScript request string sanitization.  Using this vulnerability, an authenticated attacker can execute arbitrary HTML and script code in the target browser against another Metasploit Pro user using a specially crafted request. Note that in most deployments, all Metasploit Pro users tend to enjoy privileges equivalent to local administrator.
