An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21976 in the wild and no public exploit code.\n\nAffected product: vSphere Replication. 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-2021-21976/ (Markdown: https://insights.sbomify.com/CVE-2021-21976/index.md)","id":"CVE-2021-21976","markdown":"https://insights.sbomify.com/CVE-2021-21976/index.md","name":"CVE-2021-21976","record":{"aliases":["GHSA-wcgq-jgx4-vjfw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VMware vSphere Replication","requires_auth":"high_privilege","summary":"An authenticated admin can execute arbitrary commands remotely in VMware vSphere Replication, requiring an upgrade to patched versions.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"vsphere_replication","vendor":"vmware"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"vSphere Replication 8.3.x prior to 8.3.1.2, 8.2.x prior to 8.2.1.1, 8.1.x prior to 8.1.2.3 and 6.5.x prior to 6.5.1.5 contain a post-authentication command injection vulnerability which may allow an authenticated admin user to perform a remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in vSphere Replication","id":"CVE-2021-21976","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in VMware View Planner","id":"CVE-2021-21978"},"packages":[],"prev":{"headline":"VMware Server Side Request Forgery in vRealize Operations Manager API","id":"CVE-2021-21975"},"products":["vSphere Replication"],"published":"2021-02-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-03","vendors":["n/a"]},"summary":"An authenticated admin can execute arbitrary commands remotely in VMware vSphere Replication, requiring an upgrade to patched versions.","url":"https://insights.sbomify.com/CVE-2021-21976/"}
