{"cve":"CVE-2017-7657","nvd":{"published":"2018-06-26T16:29:00.257","modified":"2026-06-17T01:24:54.153","status":"Modified","description":"In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-190","CWE-444"],"references":["http://www.securitytracker.com/id/1041194","https://access.redhat.com/errata/RHSA-2019:0910","https://bugs.eclipse.org/bugs/show_bug.cgi?id=535668","https://lists.apache.org/thread.html/053d9ce4d579b02203db18545fee5e33f35f2932885459b74d1e4272%40%3Cissues.activemq.apache.org%3E","https://lists.apache.org/thread.html/708d94141126eac03011144a971a6411fcac16d9c248d1d535a39451%40%3Csolr-user.lucene.apache.org%3E"],"products":["debian:debian_linux","eclipse:jetty","hp:xp_p9000_command_view","netapp:e-series_santricity_management","netapp:e-series_santricity_os_controller","netapp:e-series_santricity_web_services","netapp:element_software","netapp:element_software_management_node","netapp:hci_storage_nodes","netapp:oncommand_system_manager","netapp:oncommand_unified_manager","netapp:santricity_cloud_connector","netapp:snap_creator_framework","netapp:snapcenter","netapp:snapmanager","oracle:rest_data_services","oracle:retail_xstore_point_of_service"],"source":"nvd","synced_at":"2026-10-19T20:51:47.459859389+00:00"},"epss":{"cve":"CVE-2017-7657","score":0.14879,"percentile":0.96698,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vgg8-72f2-qm23","url":"https://osv.dev/vulnerability/GHSA-vgg8-72f2-qm23","summary":"Critical severity vulnerability that affects org.eclipse.jetty:jetty-server","modified":"2024-02-17T05:36:15.080820Z","packages":[{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-server","purl":"pkg:maven/org.eclipse.jetty/jetty-server","ranges":["<9.2.25.v20180606"],"fixed":["9.2.25.v20180606"]},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-server","purl":"pkg:maven/org.eclipse.jetty/jetty-server","ranges":[">=9.3.0 <9.3.24.v20180605"],"fixed":["9.3.24.v20180605"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
