Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-6972 in the wild and no public exploit code.\n\nAffected product: Vmware Esxi. 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-2018-6972/ (Markdown: https://insights.sbomify.com/CVE-2018-6972/index.md)","id":"CVE-2018-6972","markdown":"https://insights.sbomify.com/CVE-2018-6972/index.md","name":"CVE-2018-6972","record":{"aliases":["GHSA-xmm5-6qh4-9f74"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"VMware virtualization software","requires_auth":"low_privilege","summary":"Attackers with normal user privileges can crash virtual machines via a NULL pointer dereference in the RPC handler of VMware products.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"esxi","vendor":"vmware"},{"product":"fusion","vendor":"vmware"},{"product":"workstation","vendor":"vmware"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"VMware ESXi (6.7 before ESXi670-201806401-BG, 6.5 before ESXi650-201806401-BG, 6.0 before ESXi600-201806401-BG and 5.5 before ESXi550-201806401-BG), Workstation (14.x before 14.1.2), and Fusion (10.x before 10.1.2) contain a denial-of-service vulnerability due to NULL pointer dereference issue in RPC handler.
