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-2021-43807/ (Markdown: https://insights.sbomify.com/CVE-2021-43807/index.md)","id":"CVE-2021-43807","markdown":"https://insights.sbomify.com/CVE-2021-43807/index.md","name":"CVE-2021-43807","record":{"aliases":["GHSA-j4mm-7pj3-jf7v"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"opencast","vendor":"apereo"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Opencast is an Open Source Lecture Capture \u0026 Video Management for Education. Opencast versions prior to 9.10 allow HTTP method spoofing, allowing to change the assumed HTTP method via URL parameter. This allows attackers to turn HTTP GET requests into PUT requests or an HTTP form to send DELETE requests. This bypasses restrictions otherwise put on these types of requests and aids in cross-site request forgery (CSRF) attacks, which would otherwise not be possible. The vulnerability allows attackers to craft links or forms which may change the server state. This issue is fixed in Opencast 9.10 and 10.0. You can mitigate the problem by setting the `SameSite=Strict` attribute for your cookies. If this is a viable option for you depends on your integrations. We strongly recommend updating in any case.","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":"HTTP Method Spoofing in Opencast","id":"CVE-2021-43807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":null,"year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Blade `@parent` Exploitation Leading To Possible XSS in Laravel","id":"CVE-2021-43808"},"packages":[{"ecosystem":"Maven","fixed":["9.10"],"introduced":["0"],"last_affected":[],"package":"org.opencastproject:opencast-common","purl":null,"source":"GHSA-j4mm-7pj3-jf7v"},{"ecosystem":"Maven","fixed":["9.10"],"introduced":["0"],"last_affected":[],"package":"org.opencastproject:opencast-common","purl":"pkg:maven/org.opencastproject/opencast-common","source":"GHSA-j4mm-7pj3-jf7v"}],"prev":{"headline":"SQL injection in Tuleap","id":"CVE-2021-43806"},"products":["opencast"],"published":"2021-12-14","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":7.6,"headline":"Opencast allows unauthorized public access via OAI-PMH","id":"CVE-2020-5228","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":null,"url":"https://insights.sbomify.com/CVE-2021-43807/"}
