HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.33% (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.
  • Fixed version: eclipse (openSUSE:Leap 15.2) 4.9.0-lp152.3.3.1; eclipse-bootstrap (openSUSE:Leap 15.2) 4.9.0-lp152.3.3.1; rh-eclipse (Red Hat:devtools:2021) 1:4.19-4.el7_9.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to eclipse (openSUSE:Leap 15.2) 4.9.0-lp152.3.3.1; eclipse-bootstrap (openSUSE:Leap 15.2) 4.9.0-lp152.3.3.1; rh-eclipse (Red Hat:devtools:2021) 1:4.19-4.el7_9 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

In versions 4.18 and earlier of the Eclipse Platform, the Help Subsystem does not authenticate active help requests to the local help web server, allowing an unauthenticated local attacker to issue active help commands to the associated Eclipse Platform process or Eclipse Rich Client Platform process.
