HighCVSS 8.8 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.43% (FIRST EPSS).
  • Anyone who can reach it over the internet 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.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper input validation in the SSH Elevate Shell feature allows an authenticated user with permission to create or modify a shared SSH entry to execute arbitrary commands on a remote SSH host using stored elevation credentials via a crafted alternate username and user interaction with the Elevate Shell action. This affects  :  - Remote Desktop Manager 2026.2.5.0 through 2026.2.7.0 - Remote Desktop Manager 2026.1.23.0 and earlier
