It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28821 in the wild and no public exploit code.\n\nAffected product: TIBCO Enterprise Message Service. 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-2021-28821/ (Markdown: https://insights.sbomify.com/CVE-2021-28821/index.md)","id":"CVE-2021-28821","markdown":"https://insights.sbomify.com/CVE-2021-28821/index.md","name":"CVE-2021-28821","record":{"aliases":["GHSA-j7g9-pj98-m5m7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TIBCO EMS","requires_auth":"low_privilege","summary":"A local low-privileged attacker can exploit insecure file permissions in the TIBCO EMS Windows installation to execute malicious code with elevated privileges.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tibco","cpe":[{"product":"enterprise_message_service","vendor":"tibco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"The Windows Installation component of TIBCO Software Inc.'s TIBCO Enterprise Message Service, TIBCO Enterprise Message Service - Community Edition, and TIBCO Enterprise Message Service - Developer Edition contains a vulnerability that theoretically allows a low privileged attacker with local access on some versions of the Windows operating system to insert malicious software.
