Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-21951 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/rancher/rancher (Go): affected from 2.5.0; fixed in 2.5.14\n- github.com/rancher/rancher (Go): affected from 2.5.0; fixed in 2.5.14\n- github.com/rancher/rancher (Go): affected from 2.6.0; fixed in 2.6.5\n- github.com/rancher/rancher (Go): affected from 2.6.0; fixed in 2.6.5\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-2022-21951/ (Markdown: https://insights.sbomify.com/CVE-2022-21951/index.md)","id":"CVE-2022-21951","markdown":"https://insights.sbomify.com/CVE-2022-21951/index.md","name":"CVE-2022-21951","record":{"aliases":["GHSA-vrph-m5jj-c46c"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Rancher Kubernetes Management","requires_auth":"low_privilege","summary":"Attackers can intercept and modify network traffic in Rancher clusters created with specific RKE template overrides due to missing encryption.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"rancher","vendor":"suse"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"A Cleartext Transmission of Sensitive Information vulnerability in SUSE Rancher, Rancher allows attackers on the network to read and change network data due to missing encryption of data transmitted via the network when a cluster is created from an RKE template with the CNI value overridden This issue affects: SUSE Rancher Rancher versions prior to 2.5.14; Rancher versions prior to 2.6.5.","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":"Rancher: Weave CNI password is not set if RKE template is used with CNI value overridden","id":"CVE-2022-21951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2022"},"n_packages":4,"n_references":2,"next":{"headline":"SUMA unauthenticated remote DoS via resource exhaustion","id":"CVE-2022-21952"},"packages":[{"ecosystem":"Go","fixed":["2.5.14"],"introduced":["2.5.0"],"last_affected":[],"package":"github.com/rancher/rancher","purl":null,"source":"GHSA-vrph-m5jj-c46c"},{"ecosystem":"Go","fixed":["2.5.14"],"introduced":["2.5.0"],"last_affected":[],"package":"github.com/rancher/rancher","purl":"pkg:golang/github.com/rancher/rancher","source":"GHSA-vrph-m5jj-c46c"},{"ecosystem":"Go","fixed":["2.6.5"],"introduced":["2.6.0"],"last_affected":[],"package":"github.com/rancher/rancher","purl":null,"source":"GHSA-vrph-m5jj-c46c"},{"ecosystem":"Go","fixed":["2.6.5"],"introduced":["2.6.0"],"last_affected":[],"package":"github.com/rancher/rancher","purl":"pkg:golang/github.com/rancher/rancher","source":"GHSA-vrph-m5jj-c46c"}],"prev":{"headline":"canna: unsafe handling of /tmp/.iroha_unix directory","id":"CVE-2022-21950"},"products":["Rancher"],"published":"2022-05-25","related":[{"cvss_score":9.9,"headline":"Rancher vulnerable to Privilege Escalation via manipulation of Secrets","id":"CVE-2023-22647","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":9.9,"headline":"Rancher Webhook is misconfigured during upgrade process","id":"CVE-2023-22651","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":9.9,"headline":"Rancher: Exposure of sensitive fields","id":"CVE-2022-43757","kev_date_added":null,"published":"2023-02-07"},{"cvss_score":9.9,"headline":"Rancher: Plaintext storage and exposure of credentials in Rancher API and cluster.management.cattle.io object","id":"CVE-2021-36782","kev_date_added":null,"published":"2022-09-07"},{"cvss_score":9.9,"headline":"Rancher: Failure to properly sanitize credentials in cluster template answers","id":"CVE-2021-36783","kev_date_added":null,"published":"2022-09-07"},{"cvss_score":9.8,"headline":"Rancher Recreates Default User With Known Password Despite Deletion","id":"CVE-2019-11202","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":9.5,"headline":"SAML Authentication Replay in Rancher","id":"CVE-2026-44946","kev_date_added":null,"published":"2026-06-30"}],"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":"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":"2024-09-16","vendors":["SUSE"]},"summary":"Attackers can intercept and modify network traffic in Rancher clusters created with specific RKE template overrides due to missing encryption.","url":"https://insights.sbomify.com/CVE-2022-21951/"}
