Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-5228 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opencastproject:opencast-oaipmh-api (Maven): affected all versions; fixed in 7.6\n- org.opencastproject:opencast-oaipmh-api (Maven): affected all versions; fixed in 7.6\n- org.opencastproject:opencast-oaipmh-api (Maven): affected from 8.0; fixed in 8.1\n- org.opencastproject:opencast-oaipmh-api (Maven): affected from 8.0; fixed in 8.1\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-2020-5228/ (Markdown: https://insights.sbomify.com/CVE-2020-5228/index.md)","id":"CVE-2020-5228","markdown":"https://insights.sbomify.com/CVE-2020-5228/index.md","name":"CVE-2020-5228","record":{"aliases":["GHSA-6f54-3qr9-pjgj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Opencast media platform","requires_auth":"low_privilege","summary":"Attackers can access all media and metadata without authentication because the OAI-PMH endpoint is publicly accessible by default in Opencast.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"opencast","vendor":"apereo"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Opencast before 8.1 and 7.6 allows unauthorized public access to all media and metadata by default via OAI-PMH. OAI-PMH is part of the default workflow and is activated by default, requiring active user intervention of users to protect media. This leads to users unknowingly handing out public access to events without their knowledge. The problem has been addressed in Opencast 7.6 and 8.1 where the OAI-PMH endpoint is configured to require users with `ROLE_ADMIN` by default. In addition to this, Opencast 9 removes the OAI-PMH publication from the default workflow, making the publication a conscious decision users have to make by updating their workflows.","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":"Opencast allows unauthorized public access via OAI-PMH","id":"CVE-2020-5228","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2020"},"n_packages":4,"n_references":2,"next":{"headline":"Opencast stores passwords using outdated MD5 hash algorithm","id":"CVE-2020-5229"},"packages":[{"ecosystem":"Maven","fixed":["7.6"],"introduced":["0"],"last_affected":[],"package":"org.opencastproject:opencast-oaipmh-api","purl":null,"source":"GHSA-6f54-3qr9-pjgj"},{"ecosystem":"Maven","fixed":["7.6"],"introduced":["0"],"last_affected":[],"package":"org.opencastproject:opencast-oaipmh-api","purl":"pkg:maven/org.opencastproject/opencast-oaipmh-api","source":"GHSA-6f54-3qr9-pjgj"},{"ecosystem":"Maven","fixed":["8.1"],"introduced":["8.0"],"last_affected":[],"package":"org.opencastproject:opencast-oaipmh-api","purl":null,"source":"GHSA-6f54-3qr9-pjgj"},{"ecosystem":"Maven","fixed":["8.1"],"introduced":["8.0"],"last_affected":[],"package":"org.opencastproject:opencast-oaipmh-api","purl":"pkg:maven/org.opencastproject/opencast-oaipmh-api","source":"GHSA-6f54-3qr9-pjgj"}],"prev":{"headline":"Feedgen Vulnerable to XML Denial of Service Attacks","id":"CVE-2020-5227"},"products":["opencast"],"published":"2020-01-30","related":[{"cvss_score":9.9,"headline":"Files Accessible to External Parties in Opencast","id":"CVE-2021-43821","kev_date_added":null,"published":"2021-12-14"},{"cvss_score":8.7,"headline":"Authentication Bypass For Endpoints With Anonymous Access in OpenCast","id":"CVE-2020-5206","kev_date_added":null,"published":"2020-01-30"},{"cvss_score":8.1,"headline":"Opencast vulnerable to billion laughs attack (XML bomb)","id":"CVE-2021-32623","kev_date_added":null,"published":"2021-06-15"},{"cvss_score":7.7,"headline":"Opencast stores passwords using outdated MD5 hash algorithm","id":"CVE-2020-5229","kev_date_added":null,"published":"2020-01-30"},{"cvss_score":7.7,"headline":"Opencast uses unsafe identifiers","id":"CVE-2020-5230","kev_date_added":null,"published":"2020-01-30"},{"cvss_score":7.5,"headline":"Opencast publishes global system account credentials","id":"CVE-2018-16153","kev_date_added":null,"published":"2023-12-12"}],"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":"2024-08-04","vendors":["opencast"]},"summary":"Attackers can access all media and metadata without authentication because the OAI-PMH endpoint is publicly accessible by default in Opencast.","url":"https://insights.sbomify.com/CVE-2020-5228/"}
