{"cve":"CVE-2018-15756","nvd":{"published":"2018-10-18T22:29:00.443","modified":"2026-10-08T22:16:45.360","status":"Modified","description":"Spring Framework, version 5.1, versions 5.0.x prior to 5.0.10, versions 4.3.x prior to 4.3.20, and older unsupported versions on the 4.2.x branch provide support for range requests when serving static resources through the ResourceHttpRequestHandler, or starting in 5.0 when an annotated controller returns an org.springframework.core.io.Resource. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack. This vulnerability affects applications that depend on either spring-webmvc or spring-webflux. Such applications must also have a registration for serving static resources (e.g. JS, CSS, images, and others), or have an annotated controller that returns an org.springframework.core.io.Resource. Spring Boot applications that depend on spring-boot-starter-web or spring-boot-starter-webflux are ready to serve static resources out of the box and are therefore vulnerable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["http://www.securityfocus.com/bid/105703","https://lists.apache.org/thread.html/339fd112517e4873695b5115b96acdddbfc8f83b10598528d37c7d12%40%3Cissues.activemq.apache.org%3E","https://lists.apache.org/thread.html/77886fec378ee6064debb1efb6b464a4a0173b2ff0d151ed86d3a228%40%3Cissues.activemq.apache.org%3E","https://lists.apache.org/thread.html/7b156ee50ba3ecce87b33c06bf7a749d84ffee55e69bfb5eca88fcc3%40%3Cissues.activemq.apache.org%3E","https://lists.apache.org/thread.html/8a1fe70534fc52ff5c9db5ac29c55657f802cbefd7e9d9850c7052bd%40%3Cissues.activemq.apache.org%3E"],"products":["debian:debian_linux","oracle:agile_product_lifecycle_management","oracle:communications_brm_-_elastic_charging_engine","oracle:communications_converged_application_server_-_service_controller","oracle:communications_diameter_signaling_router","oracle:communications_element_manager","oracle:communications_online_mediation_controller","oracle:communications_session_report_manager","oracle:communications_session_route_manager","oracle:communications_unified_inventory_management","oracle:endeca_information_discovery_integrator","oracle:enterprise_manager_for_fusion_applications","oracle:enterprise_manager_ops_center","oracle:financial_services_analytical_applications_infrastructure","oracle:flexcube_private_banking","oracle:goldengate_application_adapters","oracle:healthcare_master_person_index","oracle:identity_manager_connector","oracle:insurance_calculation_engine","oracle:insurance_policy_administration_j2ee","oracle:insurance_rules_palette","oracle:mysql_enterprise_monitor","oracle:primavera_analytics","oracle:primavera_gateway","oracle:rapid_planning","oracle:retail_advanced_inventory_planning","oracle:retail_assortment_planning","oracle:retail_clearance_optimization_engine","oracle:retail_financial_integration","oracle:retail_integration_bus","oracle:retail_invoice_matching","oracle:retail_markdown_optimization","oracle:retail_order_broker","oracle:retail_predictive_application_server","oracle:retail_service_backbone","oracle:retail_xstore_point_of_service","oracle:tape_library_acsls","oracle:webcenter_sites","oracle:weblogic_server","vmware:spring_framework"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-15756","score":0.09207,"percentile":0.95302,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-ffvq-7w96-97p7","url":"https://osv.dev/vulnerability/GHSA-ffvq-7w96-97p7","summary":"Denial of Service in Spring Framework","modified":"2024-12-01T05:32:48.897892Z","packages":[{"ecosystem":"Maven","name":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","ranges":[">=5.1.0.RELEASE <5.1.1.RELEASE"],"fixed":["5.1.1.RELEASE"]},{"ecosystem":"Maven","name":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","ranges":[">=5.0.0.RELEASE <5.0.10.RELEASE"],"fixed":["5.0.10.RELEASE"]},{"ecosystem":"Maven","name":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","ranges":[">=4.2.0.RELEASE <4.3.20.RELEASE"],"fixed":["4.3.20.RELEASE"]}]}],"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).
