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-2023-32187 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/k3s-io/k3s (Go): affected all versions; fixed in 1.24.17\n- github.com/k3s-io/k3s (Go): affected all versions; fixed in 1.24.17\n- github.com/k3s-io/k3s (Go): affected from 1.25.0; fixed in 1.25.13\n- github.com/k3s-io/k3s (Go): affected from 1.25.0; fixed in 1.25.13\n- github.com/k3s-io/k3s (Go): affected from 1.26.0; fixed in 1.26.8\n- github.com/k3s-io/k3s (Go): affected from 1.26.0; fixed in 1.26.8\n- github.com/k3s-io/k3s (Go): affected from 1.27.0; fixed in 1.27.5\n- github.com/k3s-io/k3s (Go): affected from 1.27.0; fixed in 1.27.5\n- github.com/k3s-io/k3s (Go): affected from 1.28.0; fixed in 1.28.1\n- github.com/k3s-io/k3s (Go): affected from 1.28.0; fixed in 1.28.1\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-2023-32187/ (Markdown: https://insights.sbomify.com/CVE-2023-32187/index.md)","id":"CVE-2023-32187","markdown":"https://insights.sbomify.com/CVE-2023-32187/index.md","name":"CVE-2023-32187","record":{"aliases":["GHSA-m4hf-6vgr-75r2"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes distribution","requires_auth":"none","summary":"Attackers with network access to the K3s API server port can cause a denial of service by exhausting resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"k3s","vendor":"k3s"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"An Allocation of Resources Without Limits or Throttling vulnerability in SUSE k3s allows attackers with access to K3s servers' apiserver/supervisor port (TCP 6443) cause denial of service.\nThis issue affects k3s: from v1.24.0 before v1.24.17+k3s1, from v1.25.0 before v1.25.13+k3s1, from v1.26.0 before v1.26.8+k3s1, from sev1.27.0 before v1.27.5+k3s1, from v1.28.0 before v1.28.1+k3s1.","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":"K3s apiserver port is vulnerable to unauthenticated remote denial-of-service (DoS) attack via TLS SAN stuffing attack","id":"CVE-2023-32187","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":10,"n_references":2,"next":{"headline":"JWT token compromise can allow malicious actions including Remote Code Execution (RCE)","id":"CVE-2023-32188"},"packages":[{"ecosystem":"Go","fixed":["1.24.17"],"introduced":["0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":null,"source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.24.17"],"introduced":["0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":"pkg:golang/github.com/k3s-io/k3s","source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.25.13"],"introduced":["1.25.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":null,"source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.25.13"],"introduced":["1.25.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":"pkg:golang/github.com/k3s-io/k3s","source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.26.8"],"introduced":["1.26.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":null,"source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.26.8"],"introduced":["1.26.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":"pkg:golang/github.com/k3s-io/k3s","source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.27.5"],"introduced":["1.27.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":null,"source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.27.5"],"introduced":["1.27.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":"pkg:golang/github.com/k3s-io/k3s","source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.28.1"],"introduced":["1.28.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":null,"source":"GHSA-m4hf-6vgr-75r2"},{"ecosystem":"Go","fixed":["1.28.1"],"introduced":["1.28.0"],"last_affected":[],"package":"github.com/k3s-io/k3s","purl":"pkg:golang/github.com/k3s-io/k3s","source":"GHSA-m4hf-6vgr-75r2"}],"prev":{"headline":"RKE2 supervisor port is vulnerable to unauthenticated remote denial-of-service (DoS) attack via TLS SAN stuffing attack","id":"CVE-2023-32186"},"products":["k3s"],"published":"2023-09-18","related":[],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-25","vendors":["SUSE"]},"summary":"Attackers with network access to the K3s API server port can cause a denial of service by exhausting resources.","url":"https://insights.sbomify.com/CVE-2023-32187/"}
