Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-18110 in the wild and no public exploit code.\n\nAffected product: Atlassian Crowd. 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-2017-18110/ (Markdown: https://insights.sbomify.com/CVE-2017-18110/index.md)","id":"CVE-2017-18110","markdown":"https://insights.sbomify.com/CVE-2017-18110/index.md","name":"CVE-2017-18110","record":{"aliases":["GHSA-6w64-j998-2q4m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Crowd","requires_auth":"low_privilege","summary":"Remote attackers can read arbitrary files from the filesystem via an XML External Entity vulnerability in the administration backup restore resource.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"crowd","vendor":"atlassian"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"The administration backup restore resource in Atlassian Crowd before version 3.0.2 and from version 3.1.0 before version 3.1.1 allows remote attackers to read files from the filesystem via a XXE vulnerability.","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 Crowd","id":"CVE-2017-18110","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"XML external entity in Application Links","id":"CVE-2017-18111"},"packages":[],"prev":{"headline":"Open redirect in Crowd","id":"CVE-2017-18109"},"products":["Crowd"],"published":"2019-03-29","related":[{"cvss_score":9.8,"headline":"Atlassian Crowd and Crowd Data Center Remote Code Execution","id":"CVE-2019-11580","kev_date_added":"2021-11-03","published":"2019-06-03"},{"cvss_score":9.8,"headline":"Auth bypass in Crowd Data Center","id":"CVE-2022-43782","kev_date_added":null,"published":"2022-11-17"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-6496","kev_date_added":null,"published":"2016-12-09"},{"cvss_score":8.1,"headline":"Auth bypass in Crowd","id":"CVE-2017-18105","kev_date_added":null,"published":"2019-03-29"},{"cvss_score":8.1,"headline":"Auth bypass in Crowd","id":"CVE-2018-20238","kev_date_added":null,"published":"2019-02-13"},{"cvss_score":8,"headline":"Code injection in Crowd Data Center","id":"CVE-2023-22521","kev_date_added":null,"published":"2023-11-21"},{"cvss_score":7.9,"headline":"XML external entity in Crowd Data Center","id":"CVE-2026-21569","kev_date_added":null,"published":"2026-01-28"}],"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":"2024-09-16","vendors":["Atlassian"]},"summary":"Remote attackers can read arbitrary files from the filesystem via an XML External Entity vulnerability in the administration backup restore resource.","url":"https://insights.sbomify.com/CVE-2017-18110/"}
