An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-20892 exists.\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-2023-20892/ (Markdown: https://insights.sbomify.com/CVE-2023-20892/index.md)","id":"CVE-2023-20892","markdown":"https://insights.sbomify.com/CVE-2023-20892/index.md","name":"CVE-2023-20892","record":{"aliases":["GHSA-vmcx-3r5m-96cr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VMware vCenter Server","requires_auth":"none","summary":"A remote attacker can execute arbitrary code on the host OS via a heap overflow in the DCERPC protocol implementation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"vcenter_server","vendor":"vmware"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The vCenter Server contains a heap overflow vulnerability due to the usage of uninitialized memory in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may exploit heap-overflow vulnerability to execute arbitrary code on the underlying operating system that hosts vCenter Server.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"VMware vCenter Server heap-overflow vulnerability","id":"CVE-2023-20892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"vmware:vcenter_server","products":["vmware:vcenter_server"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in VMware Cloud Foundation (vCenter Server)","id":"CVE-2023-20893"},"packages":[],"prev":{"headline":"VMware Tanzu Application Service for VMs and Isolation Segment information disclosure vulnerability","id":"CVE-2023-20891"},"products":["VMware Cloud Foundation (vCenter Server)","VMware vCenter Server (vCenter Server)"],"published":"2023-06-22","related":[{"cvss_score":9.8,"headline":"Broadcom VMware vCenter Path Traversal","id":"CVE-2026-59310","kev_date_added":"2026-08-18","published":"2026-07-30"},{"cvss_score":9.8,"headline":"VMware vCenter Server Out-of-Bounds Write","id":"CVE-2023-34048","kev_date_added":"2024-01-22","published":"2023-10-25"},{"cvss_score":9.8,"headline":"VMware vCenter Server Information Disclosure","id":"CVE-2020-3952","kev_date_added":"2021-11-03","published":"2020-04-10"},{"cvss_score":5.3,"headline":"VMware vCenter Server Improper Access Control","id":"CVE-2021-22017","kev_date_added":"2022-01-10","published":"2021-09-23"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2015-2342","kev_date_added":null,"published":"2015-10-12"},{"cvss_score":9.8,"headline":"vCenter authentication-bypass vulnerability","id":"CVE-2026-59309","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"Memory corruption in VMware Cloud Foundation","id":"CVE-2024-37080","kev_date_added":null,"published":"2024-06-18"}],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["VMware"]},"summary":"A remote attacker can execute arbitrary code on the host OS via a heap overflow in the DCERPC protocol implementation.","url":"https://insights.sbomify.com/CVE-2023-20892/"}
