An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-j86v-2vjr-fg8f in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- go.etcd.io/etcd/v3 (Go): affected all versions; no fix listed\n- go.etcd.io/etcd/v3 (Go): affected all versions; fixed in 3.3.23\n- go.etcd.io/etcd/v3 (Go): affected all versions; fixed in 3.3.23\n- go.etcd.io/etcd/v3 (Go): affected from 3.4.0-rc.0; fixed in 3.4.10\n- go.etcd.io/etcd/v3 (Go): affected from 3.4.0-rc.0; fixed in 3.4.10\n- go.etcd.io/etcd (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/GHSA-j86v-2vjr-fg8f/ (Markdown: https://insights.sbomify.com/GHSA-j86v-2vjr-fg8f/index.md)","id":"GHSA-j86v-2vjr-fg8f","markdown":"https://insights.sbomify.com/GHSA-j86v-2vjr-fg8f/index.md","name":"GHSA-j86v-2vjr-fg8f","record":{"aliases":["GO-2024-2528"],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"etcd distributed key-value store","requires_auth":"none","summary":"Etcd gateway fails to validate TLS certificates, allowing connections to non-TLS endpoints when using discovery-srv, bypassing security expectations.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Vulnerability type\nCryptography\n\n### Workarounds\nRefer to the [gateway documentation](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/gateway.md). The vulnerability was spotted due to unclear documentation of how the gateway handles endpoints validation. \n\n### Detail\nSecure endpoint validation is performed by the etcd gateway start command when the --discovery-srv flag is enabled. However, as currently implemented, it only validates TCP reachability, effectively allowing connections to an endpoint that doesn't accept TLS connections through the HTTPS URL. The auditors has noted that appropriate documentation of this validation functionality plus deprecation of this misleading functionality is an acceptable path forward.\n\n### References\nFind out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Contact the [etcd security committee](https://github.com/etcd-io/etcd/blob/master/security/security-release-process.md#product-security-committee-psc)","ecosystems":["Go"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Etcd Gateway TLS endpoint validation only confirms TCP reachability","id":"GHSA-j86v-2vjr-fg8f","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"security_feature_bypass","year":"2024"},"n_packages":6,"n_references":null,"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd","purl":"pkg:golang/go.etcd.io/etcd","source":"GO-2024-2528"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd/v3","purl":"pkg:golang/go.etcd.io/etcd/v3","source":"GO-2024-2528"},{"ecosystem":"Go","fixed":["3.3.23"],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd/v3","purl":null,"source":"GHSA-j86v-2vjr-fg8f"},{"ecosystem":"Go","fixed":["3.3.23"],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd/v3","purl":"pkg:golang/go.etcd.io/etcd/v3","source":"GHSA-j86v-2vjr-fg8f"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0-rc.0"],"last_affected":[],"package":"go.etcd.io/etcd/v3","purl":null,"source":"GHSA-j86v-2vjr-fg8f"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0-rc.0"],"last_affected":[],"package":"go.etcd.io/etcd/v3","purl":"pkg:golang/go.etcd.io/etcd/v3","source":"GHSA-j86v-2vjr-fg8f"}],"products":null,"published":"2024-02-03","related":[],"sources":[{"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"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Etcd gateway fails to validate TLS certificates, allowing connections to non-TLS endpoints when using discovery-srv, bypassing security expectations.","url":"https://insights.sbomify.com/GHSA-j86v-2vjr-fg8f/"}
