An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-9548 exists.\n\nAffected packages and fixed versions:\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.0.0; fixed in 2.7.9.7\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.0.0; fixed in 2.7.9.7\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.8.0; fixed in 2.8.11.6\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.8.0; fixed in 2.8.11.6\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.9.0; fixed in 2.9.10.4\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.9.0; fixed in 2.9.10.4\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-2020-9548/ (Markdown: https://insights.sbomify.com/CVE-2020-9548/index.md)","id":"CVE-2020-9548","markdown":"https://insights.sbomify.com/CVE-2020-9548/index.md","name":"CVE-2020-9548","record":{"aliases":["CLEANSTART-2026-IN66246","DEBIAN-CVE-2020-9548","GHSA-p43x-xfjf-5jhr","ROOT-APP-MAVEN-CVE-2020-9548","UBUNTU-CVE-2020-9548"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Java JSON library","requires_auth":"none","summary":"Attackers can execute arbitrary code via unsafe deserialization in jackson-databind when specific gadget classes are present.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"jackson-databind","vendor":"fasterxml"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"agile_product_lifecycle_management","vendor":"oracle"},{"product":"autovue_for_agile_product_lifecycle_management","vendor":"oracle"},{"product":"banking_digital_experience","vendor":"oracle"},{"product":"banking_platform","vendor":"oracle"},{"product":"communications_calendar_server","vendor":"oracle"},{"product":"communications_contacts_server","vendor":"oracle"},{"product":"communications_diameter_signaling_router","vendor":"oracle"},{"product":"communications_element_manager","vendor":"oracle"},{"product":"communications_evolved_communications_application_server","vendor":"oracle"},{"product":"communications_instant_messaging_server","vendor":"oracle"},{"product":"communications_network_charging_and_control","vendor":"oracle"},{"product":"communications_session_report_manager","vendor":"oracle"},{"product":"communications_session_route_manager","vendor":"oracle"},{"product":"enterprise_manager_base_platform","vendor":"oracle"},{"product":"global_lifecycle_management_opatch","vendor":"oracle"},{"product":"jd_edwards_enterpriseone_orchestrator","vendor":"oracle"},{"product":"jd_edwards_enterpriseone_tools","vendor":"oracle"},{"product":"primavera_unifier","vendor":"oracle"},{"product":"retail_merchandising_system","vendor":"oracle"},{"product":"retail_sales_audit","vendor":"oracle"},{"product":"retail_xstore_point_of_service","vendor":"oracle"},{"product":"weblogic_server","vendor":"oracle"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to br.com.anteros.dbcp.AnterosDBCPConfig (aka anteros-core).","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2020-03-02","github_poc":1,"max_poc_stars":24,"metasploit":0,"nuclei":1,"refs":[{"date":"2020-03-02T13:43:47Z","kind":"github_poc","ref":"https://github.com/fairyming/CVE-2020-9548","stars":24,"title":"CVE-2020-9548：FasterXML/jackson-databind 远程代码执行漏洞"},{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-9548.yaml","stars":null,"title":"FasterXML Jackson Databind \u003c=2.9.10.4 -
