Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-23927 in the wild and no public exploit code.\n\nAffected product: Open-Xchange Open-Xchange Appsuite. 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-2021-23927/ (Markdown: https://insights.sbomify.com/CVE-2021-23927/index.md)","id":"CVE-2021-23927","markdown":"https://insights.sbomify.com/CVE-2021-23927/index.md","name":"CVE-2021-23927","record":{"aliases":["GHSA-xwhw-2q44-qw48"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OX App Suite","requires_auth":"low_privilege","summary":"Attackers can exploit a Server-Side Request Forgery vulnerability in OX App Suite to access internal resources via crafted OAuth proxy requests.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open-xchange_appsuite","vendor":"open-xchange"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"OX App Suite through 7.10.4 allows SSRF via a URL with an @ character in an appsuite/api/oauth/proxy PUT request.","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":"Server-side request forgery in n/a","id":"CVE-2021-23927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open-xchange:open-xchange_appsuite","products":["open-xchange:open-xchange_appsuite"],"type":"ssrf","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-23928"},"packages":[],"prev":{"headline":"XMLBeans XML Entity Expansion","id":"CVE-2021-23926"},"products":["n/a"],"published":"2021-01-12","related":[{"cvss_score":9.9,"headline":"Server-side request forgery in n/a","id":"CVE-2017-13667","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2020-12645","kev_date_added":null,"published":"2020-08-31"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-7158","kev_date_added":null,"published":"2019-06-17"},{"cvss_score":9.8,"headline":"Misconfiguration in n/a","id":"CVE-2017-17060","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2017-5210","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5212","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5863","kev_date_added":null,"published":"2019-05-22"}],"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":["n/a"]},"summary":"Attackers can exploit a Server-Side Request Forgery vulnerability in OX App Suite to access internal resources via crafted OAuth proxy requests.","url":"https://insights.sbomify.com/CVE-2021-23927/"}
