An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-16875 exists.\n\nAffected product: Microsoft Exchange Server. 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-2020-16875/ (Markdown: https://insights.sbomify.com/CVE-2020-16875/index.md)","id":"CVE-2020-16875","markdown":"https://insights.sbomify.com/CVE-2020-16875/index.md","name":"CVE-2020-16875","record":{"aliases":["GHSA-5rg4-jqjp-6664"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Exchange Server","requires_auth":"high_privilege","summary":"An authenticated attacker with specific Exchange roles can execute arbitrary code as System via improper cmdlet argument validation.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"exchange_server","vendor":"microsoft"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"\u003cp\u003eA remote code execution vulnerability exists in Microsoft Exchange server due to improper validation of cmdlet arguments.\u003c/p\u003e\n\u003cp\u003eAn attacker who successfully exploited the vulnerability could run arbitrary code in the context of the System user.
