Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27604 in the wild and no public exploit code.\n\nAffected product: SAP Process Integration (Enterprise Service Repository JAVA Mappings). 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-2021-27604/ (Markdown: https://insights.sbomify.com/CVE-2021-27604/index.md)","id":"CVE-2021-27604","markdown":"https://insights.sbomify.com/CVE-2021-27604/index.md","name":"CVE-2021-27604","record":{"aliases":["GHSA-98g3-884p-c9q5"],"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 ABAP","requires_auth":"low_privilege","summary":"An XML External Entity vulnerability in SAP NetWeaver ABAP allows attackers 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_process_integration","vendor":"sap"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"In order to prevent XML External Entity vulnerability in SAP NetWeaver ABAP Server and ABAP Platform (Process Integration - Enterprise Service Repository JAVA Mappings), versions - 7.10, 7.20, 7.30, 7.31, 7.40, 7.50, SAP recommends to refer this note.","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 SAP Process Integration (Enterprise Service Repository JAVA Mappings)","id":"CVE-2021-27604","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in SAP Fiori Apps 2.0 for Travel Management in SAP ERP","id":"CVE-2021-27605"},"packages":[],"prev":{"headline":"Denial of service in SAP NetWeaver AS for ABAP","id":"CVE-2021-27603"},"products":["SAP Process Integration (Enterprise Service Repository JAVA Mappings)"],"published":"2021-04-14","related":[{"cvss_score":9.9,"headline":"Missing authorization in NetWeaver Process Integration","id":"CVE-2022-41272","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":9.4,"headline":"SQL injection in NetWeaver Process Integration","id":"CVE-2022-41271","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":7.5,"headline":"Information disclosure in SAP NetWeaver Process Integration(SAP XIESR)","id":"CVE-2019-0315","kev_date_added":null,"published":"2019-06-12"},{"cvss_score":7.2,"headline":"Command injection in SAP NetWeaver Process Integration ABAP tests (SAP Basis)","id":"CVE-2019-0328","kev_date_added":null,"published":"2019-07-10"},{"cvss_score":7.1,"headline":"Security feature bypass in SAP NetWeaver Process Integration (Adapter Engine)","id":"CVE-2019-0283","kev_date_added":null,"published":"2019-04-10"},{"cvss_score":6.5,"headline":"Missing Authentication check in SAP NetWeaver Process Integration (Message Display Tool)","id":"CVE-2023-35872","kev_date_added":null,"published":"2023-07-11"}],"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":"2024-08-03","vendors":["SAP SE"]},"summary":"An XML External Entity vulnerability in SAP NetWeaver ABAP allows attackers to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-27604/"}
