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-2019-14993 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- istio.io/istio (Go): affected all versions; fixed in 1.1.13\n- istio.io/istio (Go): affected all versions; fixed in 1.1.13\n- istio.io/istio (Go): affected from 1.2.0; fixed in 1.2.4\n- istio.io/istio (Go): affected from 1.2.0; fixed in 1.2.4\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-2019-14993/ (Markdown: https://insights.sbomify.com/CVE-2019-14993/index.md)","id":"CVE-2019-14993","markdown":"https://insights.sbomify.com/CVE-2019-14993/index.md","name":"CVE-2019-14993","record":{"aliases":["GHSA-qcvw-82hh-gq38","MINI-65ph-46pc-xhcc","MINI-6x2g-rv7p-6fqp"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Istio service mesh","requires_auth":"none","summary":"Attackers can cause denial of service in Istio by sending long URIs that trigger inefficient regular expression processing in specific APIs.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-185","name":"Incorrect Regular Expression"}],"description":"Istio before 1.1.13 and 1.2.x before 1.2.4 mishandles regular expressions for long URIs, leading to a denial of service during use of the JWT, VirtualService, HTTPAPISpecBinding, or QuotaSpecBinding API.","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 ReDoS Vulnerability","id":"CVE-2019-14993","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":4,"n_references":4,"next":{"headline":"Path traversal in Jira Service Desk Data Center","id":"CVE-2019-14994"},"packages":[{"ecosystem":"Go","fixed":["1.1.13"],"introduced":["0"],"last_affected":[],"package":"istio.io/istio","purl":null,"source":"GHSA-qcvw-82hh-gq38"},{"ecosystem":"Go","fixed":["1.1.13"],"introduced":["0"],"last_affected":[],"package":"istio.io/istio","purl":"pkg:golang/istio.io/istio","source":"GHSA-qcvw-82hh-gq38"},{"ecosystem":"Go","fixed":["1.2.4"],"introduced":["1.2.0"],"last_affected":[],"package":"istio.io/istio","purl":null,"source":"GHSA-qcvw-82hh-gq38"},{"ecosystem":"Go","fixed":["1.2.4"],"introduced":["1.2.0"],"last_affected":[],"package":"istio.io/istio","purl":"pkg:golang/istio.io/istio","source":"GHSA-qcvw-82hh-gq38"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2019-14987"},"products":["n/a"],"published":"2019-08-13","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":"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":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can cause denial of service in Istio by sending long URIs that trigger inefficient regular expression processing in specific APIs.","url":"https://insights.sbomify.com/CVE-2019-14993/"}
