An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2023-34048 in the wild since at least 22 Jan 2024.\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-2023-34048/ (Markdown: https://insights.sbomify.com/CVE-2023-34048/index.md)","id":"CVE-2023-34048","markdown":"https://insights.sbomify.com/CVE-2023-34048/index.md","name":"CVE-2023-34048","record":{"aliases":["GHSA-87j2-5g9j-7jmv"],"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 trigger an out-of-bounds write in vCenter Server's DCERPC implementation to achieve remote code execution.","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":9.8,"severity":"critical","source":"cna","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-787","name":"Out-of-bounds Write"}],"description":"vCenter Server contains an out-of-bounds write vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger an out-of-bounds write potentially leading to remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-34048.yaml","stars":null,"title":"VMware vCenter Server - Out-of-Bounds Write"}],"tier":"exploited"},"has_fix":null,"headline":"VMware vCenter Server Out-of-Bounds Write","id":"CVE-2023-34048","indexable":true,"kev":{"dateAdded":"2024-01-22","dueDate":"2024-02-12","knownRansomwareCampaignUse":"Unknown","product":"vCenter Server","requiredAction":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","vendorProject":"VMware","vulnerabilityName":"VMware vCenter Server Out-of-Bounds Write Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"vmware:vcenter_server","products":["vmware:vcenter_server"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Salt security advisory release - 2023-OCT-27","id":"CVE-2023-34049"},"packages":[],"prev":{"headline":"Exposure of data and identity to wrong session in Spring for GraphQL","id":"CVE-2023-34047"},"products":["VMware Cloud Foundation (VMware vCenter Server)","VMware vCenter Server"],"published":"2023-10-25","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 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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["VMware"]},"summary":"A remote attacker can trigger an out-of-bounds write in vCenter Server's DCERPC implementation to achieve remote code execution.","url":"https://insights.sbomify.com/CVE-2023-34048/"}
