Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-1000221 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opencastproject:opencast-kernel (Maven): affected all versions; fixed in 2.2.4\n- org.opencastproject:opencast-kernel (Maven): affected all versions; fixed in 2.2.4\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-2017-1000221/ (Markdown: https://insights.sbomify.com/CVE-2017-1000221/index.md)","id":"CVE-2017-1000221","markdown":"https://insights.sbomify.com/CVE-2017-1000221/index.md","name":"CVE-2017-1000221","record":{"aliases":["GHSA-hx44-c87v-p6xg"],"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 restricted media recordings by exploiting flawed username matching in the search service, bypassing intended access controls.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"opencast","vendor":"apereo"}],"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-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"In Opencast 2.2.3 and older if user names overlap, the Opencast search service used for publication to the media modules and players will handle the access control incorrectly so that users only need to match part of the user name used for the access restriction.
