CVE-2025-30053: Missing Authentication in CGM CLININET

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 0.35% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: CGM CGM CLININET updater-upkg module update to version 5.3.0.

Low priority for now. Upgrade to CGM CGM CLININET updater-upkg module update to version 5.3.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The CGM CLININET application runs the cgm-updater process listening on an open network port without any authentication. The vulnerability was confirmed to affect versions up to 2026.MS3. Version 2026.MS3 with the updater-upkg component in version 5.3.0 or higher is not affected by this vulnerability.
