Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-16689 in the wild and no public exploit code.\n\nAffected product: SAP Trusted RFC connection. 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-2017-16689/ (Markdown: https://insights.sbomify.com/CVE-2017-16689/index.md)","id":"CVE-2017-16689","markdown":"https://insights.sbomify.com/CVE-2017-16689/index.md","name":"CVE-2017-16689","record":{"aliases":["GHSA-crwv-5x5f-fc2f"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP Kernel","requires_auth":"low_privilege","summary":"Attackers can establish trusted RFC connections to unauthorized clients or users, bypassing authentication controls in SAP Kernel.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"sap_kernel","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-287","name":"Improper Authentication"}],"description":"A Trusted RFC connection in SAP KERNEL 32NUC, SAP KERNEL 32Unicode, SAP KERNEL 64NUC, SAP KERNEL 64Unicode 7.21, 7.21EXT, 7.22, 7.22EXT; SAP KERNEL from 7.21 to 7.22, 7.45, 7.49, can be established to a different client or a different user on the same system, although no explicit Trusted/Trusting Relation to the same system has been defined.","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 Trusted RFC connection","id":"CVE-2017-16689","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2017"},"n_packages":0,"n_references":3,"next":{"headline":"Other in SAP Plant Connectivity","id":"CVE-2017-16690"},"packages":[],"prev":{"headline":"Information disclosure in SAP HANA extended application services","id":"CVE-2017-16687"},"products":["Trusted RFC connection"],"published":"2017-12-12","related":[{"cvss_score":7.5,"headline":"Denial of service in SAP GUI for Java (BC-FES-JAV)","id":"CVE-2019-0365","kev_date_added":null,"published":"2019-09-10"},{"cvss_score":7.5,"headline":"Denial of service in SAP Gateway","id":"CVE-2018-2433","kev_date_added":null,"published":"2018-07-10"},{"cvss_score":7.5,"headline":"Missing authorization in SAP Startup Service","id":"CVE-2018-2360","kev_date_added":null,"published":"2018-01-09"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-5997","kev_date_added":null,"published":"2017-02-15"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2014-9594","kev_date_added":null,"published":"2015-01-15"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2014-9595","kev_date_added":null,"published":"2015-01-15"}],"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":"2024-09-17","vendors":["SAP"]},"summary":"Attackers can establish trusted RFC connections to unauthorized clients or users, bypassing authentication controls in SAP Kernel.","url":"https://insights.sbomify.com/CVE-2017-16689/"}
