Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-2477 in the wild and no public exploit code.\n\nAffected product: Sap Netweaver. 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-2018-2477/ (Markdown: https://insights.sbomify.com/CVE-2018-2477/index.md)","id":"CVE-2018-2477","markdown":"https://insights.sbomify.com/CVE-2018-2477/index.md","name":"CVE-2018-2477","record":{"aliases":["GHSA-gwj3-xxgq-gmc6"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP NetWeaver","requires_auth":"low_privilege","summary":"An attacker can exploit insufficient XML validation in SAP NetWeaver Knowledge Management to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver","vendor":"sap"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-91","name":"XML Injection"}],"description":"Knowledge Management (XMLForms) in SAP NetWeaver, versions 7.30, 7.31, 7.40 and 7.50 does not sufficiently validate an XML document accepted from an untrusted source.","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 Knowledge Management (XMLForms) in SAP NetWeaver","id":"CVE-2018-2477","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sap:netweaver","products":["sap:netweaver"],"type":"xxe","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in SAP Basis (TREX / BWA installation)","id":"CVE-2018-2478"},"packages":[],"prev":{"headline":"Open redirect in SAP NetWeaver (forums)","id":"CVE-2018-2476"},"products":["Knowledge Management (XMLForms) in SAP NetWeaver"],"published":"2018-11-13","related":[{"cvss_score":10,"headline":"SAP NetWeaver Unrestricted File Upload","id":"CVE-2025-31324","kev_date_added":"2025-04-29","published":"2025-04-24"},{"cvss_score":9.9,"headline":"SAP NetWeaver Unrestricted File Upload","id":"CVE-2021-38163","kev_date_added":"2022-06-09","published":"2021-09-14"},{"cvss_score":9.1,"headline":"SAP NetWeaver Deserialization","id":"CVE-2025-42999","kev_date_added":"2025-05-15","published":"2025-05-13"},{"cvss_score":10,"headline":"XML external entity in n/a","id":"CVE-2013-6822","kev_date_added":null,"published":"2013-11-19"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2011-1517","kev_date_added":null,"published":"2020-02-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2013-1592","kev_date_added":null,"published":"2020-01-23"},{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2015-7241","kev_date_added":null,"published":"2017-09-06"}],"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":"2024-08-05","vendors":["SAP"]},"summary":"An attacker can exploit insufficient XML validation in SAP NetWeaver Knowledge Management to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2018-2477/"}
