Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27406 in the wild and no public exploit code.\n\nAffected product: PerFact OpenVPN-Client. 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-2021-27406/ (Markdown: https://insights.sbomify.com/CVE-2021-27406/index.md)","id":"CVE-2021-27406","markdown":"https://insights.sbomify.com/CVE-2021-27406/index.md","name":"CVE-2021-27406","record":{"aliases":["GHSA-qxvq-2x4g-3vm7"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenVPN client","requires_auth":"low_privilege","summary":"A local attacker can send arbitrary configuration commands to the OpenVPN client backend, resulting in code execution with SYSTEM privileges.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"openvpn-client","vendor":"perfact"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"},{"id":"CWE-15","name":"External Control of System or Configuration Setting"}],"description":"An attacker can take leverage on PerFact OpenVPN-Client versions 1.4.1.0 and prior to send the config command from any application running on the local host machine to force the back-end server into initializing a new open-VPN instance with arbitrary open-VPN configuration.
