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-2023-34339 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-2023-34339/ (Markdown: https://insights.sbomify.com/CVE-2023-34339/index.md)","id":"CVE-2023-34339","markdown":"https://insights.sbomify.com/CVE-2023-34339/index.md","name":"CVE-2023-34339","record":{"aliases":["GHSA-w2c4-vpgj-g3jp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kotlin web framework","requires_auth":"low_privilege","summary":"Attackers can view sensitive authentication headers in exception messages, potentially exposing credentials in logs or error responses.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"ktor","vendor":"jetbrains"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"In JetBrains Ktor before 2.3.1 headers containing authentication data could be added to the exception's message","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":"Information disclosure in Ktor","id":"CVE-2023-34339","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Accumulo: Accumulo 2.1.0 may incorrectly validate cached credentials","id":"CVE-2023-34340"},"packages":[],"prev":{"headline":"hard coded cryptographic key","id":"CVE-2023-34338"},"products":["Ktor"],"published":"2023-06-01","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":6.8,"headline":"Security feature bypass in Ktor","id":"CVE-2023-45613","kev_date_added":null,"published":"2023-10-09"},{"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":"partial"},"state":"PUBLISHED","updated":"2025-01-08","vendors":["JetBrains"]},"summary":"Attackers can view sensitive authentication headers in exception messages, potentially exposing credentials in logs or error responses.","url":"https://insights.sbomify.com/CVE-2023-34339/"}
