Windows Remote Desktop Client Information Disclosure Vulnerability

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.86% (FIRST EPSS); higher than 58.2% 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.
  • Fixed version: Windows 10 Version 1607 for 32-bit Systems 10.0.14393.9612; Windows 10 Version 1607 for x64-based Systems 10.0.14393.9612; Windows 10 Version 1809 for 32-bit Systems 10.0.17763.9376.

Low priority for now. Upgrade to Windows 10 Version 1607 for 32-bit Systems 10.0.14393.9612; Windows 10 Version 1607 for x64-based Systems 10.0.14393.9612; Windows 10 Version 1809 for 32-bit Systems 10.0.17763.9376 or later.
