An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-3952 in the wild since at least 3 Nov 2021.\n\nAffected product: Vmware Vcenter 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-2020-3952/ (Markdown: https://insights.sbomify.com/CVE-2020-3952/index.md)","id":"CVE-2020-3952","markdown":"https://insights.sbomify.com/CVE-2020-3952/index.md","name":"CVE-2020-3952","record":{"aliases":["GHSA-rqpw-v3g2-qccx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"VMware vCenter Server","requires_auth":"none","summary":"Attackers can bypass access controls in VMware vCenter Server's vmdir component, potentially gaining unauthorized access to sensitive services.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"vcenter_server","vendor":"vmware"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Under certain conditions, vmdir that ships with VMware vCenter Server, as part of an embedded or external Platform Services Controller (PSC), does not correctly implement access controls.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2020-04-09","github_poc":4,"max_poc_stars":274,"metasploit":2,"nuclei":1,"refs":[{"date":"2020-04-16T07:40:51Z","kind":"github_poc","ref":"https://github.com/guardicore/vmware_vcenter_cve_2020_3952","stars":274,"title":"Exploit for CVE-2020-3952 in vCenter 6.7"},{"date":"2020-04-15T00:51:21Z","kind":"github_poc","ref":"https://github.com/chronoloper/CVE-2020-3952","stars":4,"title":"Vuln Check"},{"date":"2020-04-19T18:35:13Z","kind":"github_poc","ref":"https://github.com/Fa1c0n35/vmware_vcenter_cve_2020_3952","stars":4,"title":"Exploit for CVE-2020-3952 in vCenter 6.7 https://www.guardicore.com/2020/04/pwning-vmware-vcenter-cve-2020-3952/"},{"date":"2020-04-17T12:39:31Z","kind":"github_poc","ref":"https://github.com/gelim/CVE-2020-3952","stars":2,"title":"VMWare vmdir missing access control exploit checker"},{"date":"2020-04-09","kind":"metasploit","ref":"auxiliary/admin/ldap/vmware_vcenter_vmdir_auth_bypass","stars":null,"title":"VMware vCenter Server vmdir Authentication Bypass"},{"date":"2020-04-09","kind":"metasploit","ref":"auxiliary/gather/vmware_vcenter_vmdir_ldap","stars":null,"title":"VMware vCenter Server vmdir Information Disclosure"},{"date":"2020-06-01","kind":"exploitdb","ref":"48535","stars":null,"title":"VMware vCenter Server 6.7 -
