An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-17186 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.syncope:syncope-core (Maven): affected all versions; fixed in 2.0.11\n- org.apache.syncope:syncope-core (Maven): affected all versions; fixed in 2.0.11\n- org.apache.syncope:syncope-core (Maven): affected from 2.1.0; fixed in 2.1.2\n- org.apache.syncope:syncope-core (Maven): affected from 2.1.0; fixed in 2.1.2\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-2018-17186/ (Markdown: https://insights.sbomify.com/CVE-2018-17186/index.md)","id":"CVE-2018-17186","markdown":"https://insights.sbomify.com/CVE-2018-17186/index.md","name":"CVE-2018-17186","record":{"aliases":["GHSA-qfjv-998w-q48f"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Syncope","requires_auth":"high_privilege","summary":"Administrators with workflow entitlements can exploit XML External Entity vulnerabilities to read/write files and execute code.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"syncope","vendor":"apache"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"An administrator with workflow definition entitlements can use DTD to perform malicious operations, including but not limited to file read, file write, and code execution.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Improper Restriction of XML External Entity Reference in org.apache.syncope:syncope-core","id":"CVE-2018-17186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2018"},"n_packages":4,"n_references":1,"next":{"headline":"Improper Certificate Validation in proton-j","id":"CVE-2018-17187"},"packages":[{"ecosystem":"Maven","fixed":["2.0.11"],"introduced":["0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":null,"source":"GHSA-qfjv-998w-q48f"},{"ecosystem":"Maven","fixed":["2.0.11"],"introduced":["0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":"pkg:maven/org.apache.syncope/syncope-core","source":"GHSA-qfjv-998w-q48f"},{"ecosystem":"Maven","fixed":["2.1.2"],"introduced":["2.1.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":null,"source":"GHSA-qfjv-998w-q48f"},{"ecosystem":"Maven","fixed":["2.1.2"],"introduced":["2.1.0"],"last_affected":[],"package":"org.apache.syncope:syncope-core","purl":"pkg:maven/org.apache.syncope/syncope-core","source":"GHSA-qfjv-998w-q48f"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2018-17185"},"products":["Apache Syncope"],"published":"2018-11-06","related":[{"cvss_score":9.8,"headline":"Apache Syncope: Remote Code Execution via Flowable BPMN Groovy ScriptTask","id":"CVE-2026-53405","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: Remote Code Execution via Scripted Connector","id":"CVE-2026-53421","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: SQL injection vulnerability in Audit Events search","id":"CVE-2026-57308","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: User self-service privilege escalation","id":"CVE-2026-62183","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Apache Syncope: RCE via Groovy Sandbox bypass","id":"CVE-2026-63071","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.8,"headline":"Expression Language Injection in Apache Syncope","id":"CVE-2020-1959","kev_date_added":null,"published":"2020-05-04"},{"cvss_score":9.8,"headline":"Injection in Apache Syncope","id":"CVE-2020-1961","kev_date_added":null,"published":"2020-05-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":["Apache Software Foundation"]},"summary":"Administrators with workflow entitlements can exploit XML External Entity vulnerabilities to read/write files and execute code.","url":"https://insights.sbomify.com/CVE-2018-17186/"}
