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-2021-25763 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-25763/ (Markdown: https://insights.sbomify.com/CVE-2021-25763/index.md)","id":"CVE-2021-25763","markdown":"https://insights.sbomify.com/CVE-2021-25763/index.md","name":"CVE-2021-25763","record":{"aliases":["GHSA-7m4m-xwpv-qmvh"],"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":"JetBrains Ktor enabled weak cipher suites by default, allowing attackers to potentially bypass cryptographic protections.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ktor","vendor":"jetbrains"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"In JetBrains Ktor before 1.4.2, weak cipher suites were enabled by default.","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":"Weak cryptography in n/a","id":"CVE-2021-25763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-25764"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2021-25762"},"products":["n/a"],"published":"2021-02-03","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"JetBrains Ktor enabled weak cipher suites by default, allowing attackers to potentially bypass cryptographic protections.","url":"https://insights.sbomify.com/CVE-2021-25763/"}
