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-2021-27610 in the wild and no public exploit code.\n\nAffected product: Sap Netweaver Application Server Abap. 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-2021-27610/ (Markdown: https://insights.sbomify.com/CVE-2021-27610/index.md)","id":"CVE-2021-27610","markdown":"https://insights.sbomify.com/CVE-2021-27610/index.md","name":"CVE-2021-27610","record":{"aliases":["GHSA-8p63-mg7m-pg66"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP NetWeaver ABAP","requires_auth":"none","summary":"Improper authentication in SAP NetWeaver ABAP allows malicious users to obtain illegitimate access to the system due to inconsistent RFC user information formatting.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver_abap","vendor":"sap"},{"product":"netweaver_application_server_abap","vendor":"sap"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"SAP NetWeaver ABAP Server and ABAP Platform, versions - 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 804, does not create information about internal and external RFC user in consistent and distinguished format, which could lead to improper authentication and may be exploited by malicious users to obtain illegitimate access to the system.","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":"Auth bypass in SAP NetWeaver AS ABAP and ABAP Platform","id":"CVE-2021-27610","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sap:netweaver_application_server_abap","products":["sap:netweaver_application_server_abap"],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Code injection in SAP NetWeaver AS ABAP","id":"CVE-2021-27611"},"packages":[],"prev":{"headline":"Missing authorization in SAP Focused RUN","id":"CVE-2021-27609"},"products":["SAP NetWeaver AS ABAP and ABAP Platform"],"published":"2021-06-16","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-4341","kev_date_added":null,"published":"2012-08-15"},{"cvss_score":8.8,"headline":"Business logic in SAP NetWeaver AS ABAP and ABAP Platform","id":"CVE-2021-38178","kev_date_added":null,"published":"2021-10-12"},{"cvss_score":7.5,"headline":"Denial of service in SAP NetWeaver Application Server for ABAP (Kernel) and ABAP Platform (Kernel)","id":"CVE-2022-22543","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":7.5,"headline":"Denial of service in SAP NetWeaver AS ABAP and ABAP Platform","id":"CVE-2021-38181","kev_date_added":null,"published":"2021-10-12"},{"cvss_score":7.5,"headline":"Denial of service in SAP NetWeaver AS for ABAP (RFC Gateway)","id":"CVE-2021-27597","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":7.5,"headline":"Memory corruption in SAP NetWeaver AS for ABAP (RFC Gateway)","id":"CVE-2021-27633","kev_date_added":null,"published":"2021-06-09"}],"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":"Improper authentication in SAP NetWeaver ABAP allows malicious users to obtain illegitimate access to the system due to inconsistent RFC user information formatting.","url":"https://insights.sbomify.com/CVE-2021-27610/"}
