An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-15756 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework:spring-core (Maven): affected from 4.2.0.RELEASE; fixed in 4.3.20.RELEASE\n- org.springframework:spring-core (Maven): affected from 4.2.0.RELEASE; fixed in 4.3.20.RELEASE\n- org.springframework:spring-core (Maven): affected from 5.0.0.RELEASE; fixed in 5.0.10.RELEASE\n- org.springframework:spring-core (Maven): affected from 5.0.0.RELEASE; fixed in 5.0.10.RELEASE\n- org.springframework:spring-core (Maven): affected from 5.1.0.RELEASE; fixed in 5.1.1.RELEASE\n- org.springframework:spring-core (Maven): affected from 5.1.0.RELEASE; fixed in 5.1.1.RELEASE\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2018-15756/ (Markdown: https://insights.sbomify.com/CVE-2018-15756/index.md)","id":"CVE-2018-15756","markdown":"https://insights.sbomify.com/CVE-2018-15756/index.md","name":"CVE-2018-15756","record":{"aliases":["DEBIAN-CVE-2018-15756","GHSA-ffvq-7w96-97p7","UBUNTU-CVE-2018-15756"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Attackers can cause denial of service in Spring Framework applications by sending malicious range headers to static resource handlers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"agile_product_lifecycle_management","vendor":"oracle"},{"product":"communications_brm_-_elastic_charging_engine","vendor":"oracle"},{"product":"communications_converged_application_server_-_service_controller","vendor":"oracle"},{"product":"communications_diameter_signaling_router","vendor":"oracle"},{"product":"communications_element_manager","vendor":"oracle"},{"product":"communications_online_mediation_controller","vendor":"oracle"},{"product":"communications_session_report_manager","vendor":"oracle"},{"product":"communications_session_route_manager","vendor":"oracle"},{"product":"communications_unified_inventory_management","vendor":"oracle"},{"product":"endeca_information_discovery_integrator","vendor":"oracle"},{"product":"enterprise_manager_for_fusion_applications","vendor":"oracle"},{"product":"enterprise_manager_ops_center","vendor":"oracle"},{"product":"financial_services_analytical_applications_infrastructure","vendor":"oracle"},{"product":"flexcube_private_banking","vendor":"oracle"},{"product":"goldengate_application_adapters","vendor":"oracle"},{"product":"healthcare_master_person_index","vendor":"oracle"},{"product":"identity_manager_connector","vendor":"oracle"},{"product":"insurance_calculation_engine","vendor":"oracle"},{"product":"insurance_policy_administration_j2ee","vendor":"oracle"},{"product":"insurance_rules_palette","vendor":"oracle"},{"product":"mysql_enterprise_monitor","vendor":"oracle"},{"product":"primavera_analytics","vendor":"oracle"},{"product":"primavera_gateway","vendor":"oracle"},{"product":"rapid_planning","vendor":"oracle"},{"product":"retail_advanced_inventory_planning","vendor":"oracle"},{"product":"retail_assortment_planning","vendor":"oracle"},{"product":"retail_clearance_optimization_engine","vendor":"oracle"},{"product":"retail_financial_integration","vendor":"oracle"},{"product":"retail_integration_bus","vendor":"oracle"},{"product":"retail_invoice_matching","vendor":"oracle"},{"product":"retail_markdown_optimization","vendor":"oracle"},{"product":"retail_order_broker","vendor":"oracle"},{"product":"retail_predictive_application_server","vendor":"oracle"},{"product":"retail_service_backbone","vendor":"oracle"},{"product":"retail_xstore_point_of_service","vendor":"oracle"},{"product":"tape_library_acsls","vendor":"oracle"},{"product":"webcenter_sites","vendor":"oracle"},{"product":"weblogic_server","vendor":"oracle"},{"product":"spring_framework","vendor":"vmware"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"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.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"DoS Attack via Range Requests","id":"CVE-2018-15756","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"debian:debian_linux","products":["debian:debian_linux","oracle:agile_product_lifecycle_management","oracle:communications_diameter_signaling_router","oracle:communications_element_manager","oracle:communications_session_report_manager","oracle:communications_session_route_manager","oracle:communications_unified_inventory_management","oracle:enterprise_manager_ops_center","oracle:financial_services_analytical_applications_infrastructure","oracle:flexcube_private_banking","oracle:mysql_enterprise_monitor","oracle:primavera_gateway","oracle:retail_xstore_point_of_service","oracle:webcenter_sites","oracle:weblogic_server","vmware:spring_framework"],"type":"denial_of_service","year":"2018"},"n_packages":6,"n_references":21,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2018-15757"},"packages":[{"ecosystem":"Maven","fixed":["4.3.20.RELEASE"],"introduced":["4.2.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":null,"source":"GHSA-ffvq-7w96-97p7"},{"ecosystem":"Maven","fixed":["4.3.20.RELEASE"],"introduced":["4.2.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","source":"GHSA-ffvq-7w96-97p7"},{"ecosystem":"Maven","fixed":["5.0.10.RELEASE"],"introduced":["5.0.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":null,"source":"GHSA-ffvq-7w96-97p7"},{"ecosystem":"Maven","fixed":["5.0.10.RELEASE"],"introduced":["5.0.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","source":"GHSA-ffvq-7w96-97p7"},{"ecosystem":"Maven","fixed":["5.1.1.RELEASE"],"introduced":["5.1.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":null,"source":"GHSA-ffvq-7w96-97p7"},{"ecosystem":"Maven","fixed":["5.1.1.RELEASE"],"introduced":["5.1.0.RELEASE"],"last_affected":[],"package":"org.springframework:spring-core","purl":"pkg:maven/org.springframework/spring-core","source":"GHSA-ffvq-7w96-97p7"}],"prev":{"headline":"CF networking internal policy server SQL injection","id":"CVE-2018-15755"},"products":["Spring framework"],"published":"2018-10-18","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["Pivotal"]},"summary":"Attackers can cause denial of service in Spring Framework applications by sending malicious range headers to static resource handlers.","url":"https://insights.sbomify.com/CVE-2018-15756/"}
