MediumCVSS 6.9 · v4.0—No exploit Fix available

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: 0.42% (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: jetty12 (Debian:14) 12.0.39-1; org.eclipse.jetty:jetty-server (Maven) 12.0.36, 12.1.10; openvox-server (Red Hat:satellite_capsule:6.16::el8) 0:8.15.2-1.el8sat.

Low priority for now. Upgrade to jetty12 (Debian:14) 12.0.39-1; org.eclipse.jetty:jetty-server (Maven) 12.0.36, 12.1.10; openvox-server (Red Hat:satellite_capsule:6.16::el8) 0:8.15.2-1.el8sat 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 Eclipse Jetty, a first HTTP/1.1 request with trailers causes the server to retain the trailers in subsequent requests performed over the same connection. Subsequent request that do not have trailers report the trailers of the first request. Subsequent request that do have trailers report the union of trailers of the first request and the current request.
