It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8872 in the wild and no public exploit code.\n\nAffected product: Parallels Parallels Desktop. 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-2020-8872/ (Markdown: https://insights.sbomify.com/CVE-2020-8872/index.md)","id":"CVE-2020-8872","markdown":"https://insights.sbomify.com/CVE-2020-8872/index.md","name":"CVE-2020-8872","record":{"aliases":["GHSA-387x-hprp-5mf9"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Parallels Desktop","requires_auth":"high_privilege","summary":"Local attackers with high privileges in the guest can read out-of-bounds memory in the xHCI component, potentially leading to hypervisor code execution.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"parallels_desktop","vendor":"parallels"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.1-47117. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the xHCI component. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
