Nablarch 5, published on 12 Mar 2019. 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-2019-5918 in the wild and no public exploit code.\n\nAffected product: TIS Inc. Nablarch 5. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2019-5918/ (Markdown: https://insights.sbomify.com/CVE-2019-5918/index.md)","id":"CVE-2019-5918","markdown":"https://insights.sbomify.com/CVE-2019-5918/index.md","name":"CVE-2019-5918","record":{"aliases":["GHSA-qm84-429w-3353"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java application framework","requires_auth":"none","summary":"Remote attackers can exploit XML External Entity vulnerabilities in the Nablarch framework to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"nablarch","vendor":"nablarch_project"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Nablarch 5 (5, and 5u1 to 5u13) allows remote attackers to conduct XML External Entity (XXE) attacks via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"XML external entity in Nablarch 5","id":"CVE-2019-5918","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Nablarch Incomplete Cryptography","id":"CVE-2019-5919"},"packages":[],"prev":{"headline":"Denial of service in azure-umqtt-c","id":"CVE-2019-5917"},"products":["Nablarch 5"],"published":"2019-03-12","related":[{"cvss_score":9.1,"headline":"Nablarch Incomplete Cryptography","id":"CVE-2019-5919","kev_date_added":null,"published":"2019-03-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["TIS Inc."]},"summary":"Remote attackers can exploit XML External Entity vulnerabilities in the Nablarch framework to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2019-5918/"}
