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-2019-8336 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/consul (Go): affected from 1.4.0; fixed in 1.4.3\n- github.com/hashicorp/consul (Go): affected from 1.4.0; fixed in 1.4.3\n- github.com/hashicorp/consul (Go): affected from 1.4.0; fixed in 1.4.3\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-2019-8336/ (Markdown: https://insights.sbomify.com/CVE-2019-8336/index.md)","id":"CVE-2019-8336","markdown":"https://insights.sbomify.com/CVE-2019-8336/index.md","name":"CVE-2019-8336","record":{"aliases":["GHSA-fhm8-cxcv-pwvc","GO-2023-1945"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Service discovery tool","requires_auth":"none","summary":"Attackers can bypass access restrictions to obtain privileges of arbitrary tokens in secondary datacenters by exploiting a hardcoded secret value.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"consul","vendor":"hashicorp"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"HashiCorp Consul (and Consul Enterprise) 1.4.x before 1.4.3 allows a client to bypass intended access restrictions and obtain the privileges of one other arbitrary token within secondary datacenters, because a token with literally \"\u003chidden\u003e\" as its secret is used in unusual circumstances.","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":"HashiCorp Consul Access Restriction Bypass","id":"CVE-2019-8336","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2019"},"n_packages":3,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2019-8337"},"packages":[{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["1.4.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":null,"source":"GHSA-fhm8-cxcv-pwvc"},{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["1.4.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":"pkg:golang/github.com/hashicorp/consul","source":"GHSA-fhm8-cxcv-pwvc"},{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["1.4.0"],"last_affected":[],"package":"github.com/hashicorp/consul","purl":"pkg:golang/github.com/hashicorp/consul","source":"GO-2023-1945"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2019-8335"},"products":["n/a"],"published":"2019-03-05","related":[{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-41805","kev_date_added":null,"published":"2021-12-12"},{"cvss_score":8.8,"headline":"HashiCorp Consul Privilege Escalation Vulnerability","id":"CVE-2021-37219","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.7,"headline":"Consul Envoy Extension Downsteam Proxy Configuration By Upstream Service Owner","id":"CVE-2023-2816","kev_date_added":null,"published":"2023-06-02"},{"cvss_score":8.3,"headline":"Consul L7 Intentions Vulnerable To Headers Bypass","id":"CVE-2024-10006","kev_date_added":null,"published":"2024-10-30"},{"cvss_score":8.1,"headline":"Consul L7 Intentions Vulnerable To URL Path Bypass","id":"CVE-2024-10005","kev_date_added":null,"published":"2024-10-30"},{"cvss_score":7.5,"headline":"Hashicorp Consul Missing SSL Certificate Validation","id":"CVE-2021-32574","kev_date_added":null,"published":"2021-07-17"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can bypass access restrictions to obtain privileges of arbitrary tokens in secondary datacenters by exploiting a hardcoded secret value.","url":"https://insights.sbomify.com/CVE-2019-8336/"}
