Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 8.2% (FIRST EPSS); higher than 94.9% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: jetty9 (Debian:10) 9.4.50-4+deb10u1; jetty9 (Debian:12) 9.4.35-1; org.eclipse.jetty:jetty-server (Maven) 9.4.35.v20201120.
- Mentioned 4 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to jetty9 (Debian:10) 9.4.50-4+deb10u1; jetty9 (Debian:12) 9.4.35-1; org.eclipse.jetty:jetty-server (Maven) 9.4.35.v20201120 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 version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.
