Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3312 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opencms:opencms-core (Maven): affected from 11.0.0; fixed in 12.0.0\n- org.opencms:opencms-core (Maven): affected from 11.0.0; fixed in 12.0.0\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-2021-3312/ (Markdown: https://insights.sbomify.com/CVE-2021-3312/index.md)","id":"CVE-2021-3312","markdown":"https://insights.sbomify.com/CVE-2021-3312/index.md","name":"CVE-2021-3312","record":{"aliases":["GHSA-g6v7-vqhx-6v6c"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCms","requires_auth":"low_privilege","summary":"Authenticated users with edit privileges can exfiltrate server files via crafted SVG documents in OpenCms.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"opencms","vendor":"alkacon"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"An XML external entity (XXE) vulnerability in Alkacon OpenCms 11.0, 11.0.1 and 11.0.2 allows remote authenticated users with edit privileges to exfiltrate files from the server's file system by uploading a crafted SVG document.","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":"XML External Entity Reference in org.opencms:opencms-core","id":"CVE-2021-3312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Plone XSS in User Fullname Property and File Upload","id":"CVE-2021-3313"},"packages":[{"ecosystem":"Maven","fixed":["12.0.0"],"introduced":["11.0.0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":null,"source":"GHSA-g6v7-vqhx-6v6c"},{"ecosystem":"Maven","fixed":["12.0.0"],"introduced":["11.0.0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":"pkg:maven/org.opencms/opencms-core","source":"GHSA-g6v7-vqhx-6v6c"}],"prev":{"headline":"October CMS Session ID not invalidated after logout","id":"CVE-2021-3311"},"products":["n/a"],"published":"2021-10-08","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-8811","kev_date_added":null,"published":"2018-03-20"},{"cvss_score":7.8,"headline":"Alkacon OpenCMS CSV Injection via New User module","id":"CVE-2019-11819","kev_date_added":null,"published":"2019-05-08"},{"cvss_score":6.8,"headline":"Cross-site scripting in n/a","id":"CVE-2005-4475","kev_date_added":null,"published":"2005-12-22"},{"cvss_score":6.5,"headline":"OpenCMS Cross-Site Scripting vulnerability","id":"CVE-2024-42699","kev_date_added":null,"published":"2025-04-21"},{"cvss_score":6.5,"headline":"Alkacon OpenCMS Improper Access Control via system/workplace/views/admin/admin-main.jsp","id":"CVE-2006-3935","kev_date_added":null,"published":"2006-07-31"},{"cvss_score":6.4,"headline":"Cross-Site Scripting stored in Alkacon OpenCMS","id":"CVE-2024-5520","kev_date_added":null,"published":"2024-05-30"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Authenticated users with edit privileges can exfiltrate server files via crafted SVG documents in OpenCms.","url":"https://insights.sbomify.com/CVE-2021-3312/"}
