An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-45613 in the wild and no public exploit code.\n\nAffected product: JetBrains Ktor. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-45613/ (Markdown: https://insights.sbomify.com/CVE-2023-45613/index.md)","id":"CVE-2023-45613","markdown":"https://insights.sbomify.com/CVE-2023-45613/index.md","name":"CVE-2023-45613","record":{"aliases":["GHSA-2fvw-ppfc-cm77"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kotlin web framework","requires_auth":"none","summary":"Attackers can bypass TLS certificate validation in JetBrains Ktor, enabling man-in-the-middle attacks against secure connections.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"ktor","vendor":"jetbrains"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"In JetBrains Ktor before 2.3.5 server certificates were not verified","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in Ktor","id":"CVE-2023-45613","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Aruba Access Points: 100 Series; 103 Series; 110 Series; 120 Series; 130 Series; 200 Series; 207 Series; 210 Series; 220 Series; 260 Series; 300 Series; 303 Series; 310 Series; 318 Series Hardened Access Points; 320 Series; 330 Series; 340 Series; 370 Series; 500 Series; 510 Series; 530 Series; 550 Series; 630 Series; 650 Series;","id":"CVE-2023-45614"},"packages":[],"prev":{"headline":"XML external entity in Ktor","id":"CVE-2023-45612"},"products":["Ktor"],"published":"2023-10-09","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12736","kev_date_added":null,"published":"2019-10-02"},{"cvss_score":8.7,"headline":"SHA1 implementation in JetBrains Ktor Native 2.0.0 was returning the same value.","id":"CVE-2022-29930","kev_date_added":null,"published":"2022-05-12"},{"cvss_score":8.6,"headline":"XML external entity in Ktor","id":"CVE-2023-45612","kev_date_added":null,"published":"2023-10-09"},{"cvss_score":7.5,"headline":"Path traversal in Ktor","id":"CVE-2022-48476","kev_date_added":null,"published":"2023-04-24"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2021-43203","kev_date_added":null,"published":"2021-11-09"},{"cvss_score":6.5,"headline":"Other in n/a","id":"CVE-2020-26129","kev_date_added":null,"published":"2020-11-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-18","vendors":["JetBrains"]},"summary":"Attackers can bypass TLS certificate validation in JetBrains Ktor, enabling man-in-the-middle attacks against secure connections.","url":"https://insights.sbomify.com/CVE-2023-45613/"}
