It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-12243 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- istio.io/istio (Go): affected from 1.1.0; fixed in 1.1.7\n- istio.io/istio (Go): affected from 1.1.0; fixed in 1.1.7\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-2019-12243/ (Markdown: https://insights.sbomify.com/CVE-2019-12243/index.md)","id":"CVE-2019-12243","markdown":"https://insights.sbomify.com/CVE-2019-12243/index.md","name":"CVE-2019-12243","record":{"aliases":["GHSA-6g5f-f5pm-mjrg"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Istio service mesh","requires_auth":"none","summary":"Attackers can bypass access controls in Istio service mesh, potentially accessing unauthorized resources or services.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"istio","vendor":"istio"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"Istio 1.1.x through 1.1.6 has Incorrect Access Control.","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":"Istio may not check inbound TCP connections against istio-policy","id":"CVE-2019-12243","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2019"},"n_packages":2,"n_references":2,"next":{"headline":"Lack of access control on upoaded files","id":"CVE-2019-12245"},"packages":[{"ecosystem":"Go","fixed":["1.1.7"],"introduced":["1.1.0"],"last_affected":[],"package":"istio.io/istio","purl":null,"source":"GHSA-6g5f-f5pm-mjrg"},{"ecosystem":"Go","fixed":["1.1.7"],"introduced":["1.1.0"],"last_affected":[],"package":"istio.io/istio","purl":"pkg:golang/istio.io/istio","source":"GHSA-6g5f-f5pm-mjrg"}],"prev":{"headline":"Deserialization in n/a","id":"CVE-2019-12241"},"products":["n/a"],"published":"2019-06-05","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2021-31921","kev_date_added":null,"published":"2021-06-02"},{"cvss_score":8.8,"headline":"Information disclosure in n/a","id":"CVE-2021-34824","kev_date_added":null,"published":"2021-06-29"},{"cvss_score":8.7,"headline":"Istio JWKS resolver to prevent private key material from being exposed when JWKS fetch fails.","id":"CVE-2026-31837","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.3,"headline":"Authorization Policy Bypass Due to Case Insensitive Host Comparison","id":"CVE-2021-39155","kev_date_added":null,"published":"2021-08-24"},{"cvss_score":8.1,"headline":"Fragments in Path May Lead to Authorization Policy Bypass","id":"CVE-2021-39156","kev_date_added":null,"published":"2021-08-24"},{"cvss_score":7.6,"headline":"Istio may allow identity impersonation if user has localhost access","id":"CVE-2022-39388","kev_date_added":null,"published":"2022-11-10"},{"cvss_score":7.5,"headline":"Istio vulnerable to denial of service attack due to Golang Regex Library","id":"CVE-2022-39278","kev_date_added":null,"published":"2022-10-13"}],"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":"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 controls in Istio service mesh, potentially accessing unauthorized resources or services.","url":"https://insights.sbomify.com/CVE-2019-12243/"}
