Noroxi assessment
Priority: Plan (action score 41/100)
- 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: 20.7% (FIRST EPSS); higher than 97.5% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS
Microsoft Windows 8.1, Windows RT 8.1, and Windows 10 Gold, 1511, and 1607 do not properly check NTLM SSO requests for MSA logins, which makes it easier for remote attackers to determine passwords via a brute-force attack on NTLM password hashes, aka "Microsoft Information Disclosure Vulnerability."
