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-2016-3720 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.fasterxml.jackson.dataformat:jackson-dataformat-xml (Maven): affected all versions; fixed in 2.7.4\n- com.fasterxml.jackson.dataformat:jackson-dataformat-xml (Maven): affected all versions; fixed in 2.7.4\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-2016-3720/ (Markdown: https://insights.sbomify.com/CVE-2016-3720/index.md)","id":"CVE-2016-3720","markdown":"https://insights.sbomify.com/CVE-2016-3720/index.md","name":"CVE-2016-3720","record":{"aliases":["DEBIAN-CVE-2016-3720","GHSA-hmq6-frv3-4727","MGASA-2016-0175","UBUNTU-CVE-2016-3720"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Jackson XML library","requires_auth":"none","summary":"Attackers can exploit an XML External Entity vulnerability in the Jackson XML library to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"jackson-dataformat-xml","vendor":"fasterxml"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"XML external entity (XXE) vulnerability in XmlMapper in the Data format extension for Jackson (aka jackson-dataformat-xml) allows attackers to have unspecified impact via unknown vectors.","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":"jackson-dataformat-xml vulnerable to XML external entity (XXE)","id":"CVE-2016-3720","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"xxe","year":"2016"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins allows Remote Users to Inject Build Parameters","id":"CVE-2016-3721"},"packages":[{"ecosystem":"Maven","fixed":["2.7.4"],"introduced":["0"],"last_affected":[],"package":"com.fasterxml.jackson.dataformat:jackson-dataformat-xml","purl":null,"source":"GHSA-hmq6-frv3-4727"},{"ecosystem":"Maven","fixed":["2.7.4"],"introduced":["0"],"last_affected":[],"package":"com.fasterxml.jackson.dataformat:jackson-dataformat-xml","purl":"pkg:maven/com.fasterxml.jackson.dataformat/jackson-dataformat-xml","source":"GHSA-hmq6-frv3-4727"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2016-3719"},"products":["n/a"],"published":"2016-06-10","related":[{"cvss_score":8.6,"headline":"jackson-dataformat-xml vulnerable to server side request forgery (SSRF)","id":"CVE-2016-7051","kev_date_added":null,"published":"2017-04-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can exploit an XML External Entity vulnerability in the Jackson XML library to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2016-3720/"}
