An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-4024 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/containers/podman/v3 (Go): affected all versions; fixed in 3.4.3\n- github.com/containers/podman/v3 (Go): affected all versions; fixed in 3.4.3\n- github.com/containers/podman/v3 (Go): affected all versions; fixed in 3.4.3\n- github.com/containers/podman (Go): affected all versions; no fix listed\n- github.com/containers/podman/v2 (Go): affected all versions; no fix listed\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-2021-4024/ (Markdown: https://insights.sbomify.com/CVE-2021-4024/index.md)","id":"CVE-2021-4024","markdown":"https://insights.sbomify.com/CVE-2021-4024/index.md","name":"CVE-2021-4024","record":{"aliases":["DEBIAN-CVE-2021-4024","GHSA-3cf2-x423-x582","GO-2022-0281","UBUNTU-CVE-2021-4024"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Podman machine","requires_auth":"none","summary":"An attacker can use the gvproxy API to forward host ports to VM services, exposing private services or disrupting host operations.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"podman","vendor":"podman_project"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making private services on the VM accessible to the network. This issue could be also used to interrupt the host's services by forwarding all ports to the VM.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Exposure of Sensitive Information to an Unauthorized Actor and Origin Validation Error in podman","id":"CVE-2021-4024","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"fedoraproject:fedora","products":["fedoraproject:fedora","redhat:enterprise_linux"],"type":"ssrf","year":"2021"},"n_packages":5,"n_references":3,"next":{"headline":"Improper Access Control in bookstackapp/bookstack","id":"CVE-2021-4026"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/containers/podman","purl":"pkg:golang/github.com/containers/podman","source":"GO-2022-0281"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/containers/podman/v2","purl":"pkg:golang/github.com/containers/podman/v2","source":"GO-2022-0281"},{"ecosystem":"Go","fixed":["3.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/containers/podman/v3","purl":null,"source":"GHSA-3cf2-x423-x582"},{"ecosystem":"Go","fixed":["3.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/containers/podman/v3","purl":"pkg:golang/github.com/containers/podman/v3","source":"GHSA-3cf2-x423-x582"},{"ecosystem":"Go","fixed":["3.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/containers/podman/v3","purl":"pkg:golang/github.com/containers/podman/v3","source":"GO-2022-0281"}],"prev":{"headline":"Denial of service in kernel","id":"CVE-2021-4023"},"products":["podman"],"published":"2021-12-23","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An attacker can use the gvproxy API to forward host ports to VM services, exposing private services or disrupting host operations.","url":"https://insights.sbomify.com/CVE-2021-4024/"}
