It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-4034 in the wild since at least 27 Jun 2022, including in ransomware campaigns.\n\nAffected product: Canonical Ubuntu Linux. 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-2021-4034/ (Markdown: https://insights.sbomify.com/CVE-2021-4034/index.md)","id":"CVE-2021-4034","markdown":"https://insights.sbomify.com/CVE-2021-4034/index.md","name":"CVE-2021-4034","record":{"aliases":["ALSA-2022:0267","AZL-8335","CLSA-2022-1643211736","CLSA-2022-1643211885","CLSA-2022-1643211942","CLSA-2022-1643212149","CLSA-2022-1643291562","DEBIAN-CVE-2021-4034","DLA-2899-1","DSA-5059-1","GHSA-qgr2-xgqv-24x8","MGASA-2022-0037","OESA-2022-1502","RHSA-2022:0265","RHSA-2022:0266","RHSA-2022:0267","RHSA-2022:0268","RHSA-2022:0269","RHSA-2022:0270","RHSA-2022:0271","RHSA-2022:0272","RHSA-2022:0273","RHSA-2022:0274","RLSA-2022:0267","SUSE-SU-2022:0189-1","SUSE-SU-2022:0190-1","SUSE-SU-2022:0191-1","UBUNTU-CVE-2021-4034","USN-5252-1","USN-5252-2","openSUSE-SU-2022:0190-1","openSUSE-SU-2024:11780-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux polkit pkexec","requires_auth":"low_privilege","summary":"Local attackers can exploit a memory corruption flaw in pkexec to execute arbitrary code and gain root privileges on Linux systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"http_server","vendor":"oracle"},{"product":"zfs_storage_appliance_kit","vendor":"oracle"},{"product":"polkit","vendor":"polkit_project"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems_eus","vendor":"redhat"},{"product":"enterprise_linux_for_power_big_endian","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian_eus","vendor":"redhat"},{"product":"enterprise_linux_for_scientific_computing","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_server_update_services_for_sap_solutions","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"scalance_lpe9403_firmware","vendor":"siemens"},{"product":"sinumerik_edge","vendor":"siemens"},{"product":"command_center","vendor":"starwindsoftware"},{"product":"starwind_virtual_san","vendor":"starwindsoftware"},{"product":"enterprise_storage","vendor":"suse"},{"product":"linux_enterprise_desktop","vendor":"suse"},{"product":"linux_enterprise_high_performance_computing","vendor":"suse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"linux_enterprise_workstation_extension","vendor":"suse"},{"product":"manager_proxy","vendor":"suse"},{"product":"manager_server","vendor":"suse"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.","ecosystems":["AlmaLinux:8","Red
