Noroxi assessment
Priority: Monitor (action score 13/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.31% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

Rapid7 Metasploit Pro version 4.16.0-2019081901 and prior suffers from an instance of CWE-732, wherein the unique server.key is written to the file system during installation with world-readable permissions. This can allow other users of the same system where Metasploit Pro is installed to intercept otherwise private communications to the Metasploit Pro web interface.
