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-2023-1412 in the wild and no public exploit code.\n\nAffected product: Cloudflare WARP. 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-2023-1412/ (Markdown: https://insights.sbomify.com/CVE-2023-1412/index.md)","id":"CVE-2023-1412","markdown":"https://insights.sbomify.com/CVE-2023-1412/index.md","name":"CVE-2023-1412","record":{"aliases":[],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cloudflare WARP Client","requires_auth":"low_privilege","summary":"Unprivileged users can escalate to SYSTEM privileges via MSI installer repair flaws, allowing arbitrary file access and system manipulation.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cloudflare","cpe":[{"product":"warp","vendor":"cloudflare"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"An unprivileged (non-admin) user can exploit an Improper Access Control vulnerability in the Cloudflare WARP Client for Windows (\u003c= 2022.12.582.0) to perform privileged operations with SYSTEM context by working with a combination of opportunistic locks (oplock) and symbolic links (which can both be created by an unprivileged user).\n\nAfter installing the Cloudflare WARP Client (admin privileges required), an MSI-Installer is placed under C:\\Windows\\Installer. The vulnerability lies in the repair function of this MSI.\n\nImpactAn unprivileged (non-admin) user can exploit this vulnerability to perform privileged operations with SYSTEM context, including deleting arbitrary files and reading arbitrary file content. This can lead to a variety of attacks, including the manipulation of system files and privilege escalation.\n\nPatchesA new installer with a fix that addresses this vulnerability was released in version 2023.3.381.0.
