Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2010-4020 in the wild and no public exploit code.\n\nAffected product: Mit Kerberos 5. 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-2010-4020/ (Markdown: https://insights.sbomify.com/CVE-2010-4020/index.md)","id":"CVE-2010-4020","markdown":"https://insights.sbomify.com/CVE-2010-4020/index.md","name":"CVE-2010-4020","record":{"aliases":["DEBIAN-CVE-2010-4020","GHSA-27hw-qqm8-6prm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kerberos authentication server","requires_auth":"low_privilege","summary":"Remote authenticated users can forge Kerberos signatures due to weak RC4 key derivation, potentially gaining privileges.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos_5","vendor":"mit"}],"cvss":{"score":6.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations.","ecosystems":[],"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":"Weak cryptography in n/a","id":"CVE-2010-4020","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"weak_cryptography","year":"2010"},"n_packages":0,"n_references":23,"next":{"headline":"Auth bypass in n/a","id":"CVE-2010-4021"},"packages":[],"prev":{"headline":"This candidate is unused by its CNA.","id":"CVE-2010-4017"},"products":["n/a"],"published":"2010-12-02","related":[{"cvss_score":10,"headline":"Use after free in n/a","id":"CVE-2011-0285","kev_date_added":null,"published":"2011-04-15"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0947","kev_date_added":null,"published":"2008-03-19"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2007-5902","kev_date_added":null,"published":"2007-12-06"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-4743","kev_date_added":null,"published":"2007-09-06"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-3999","kev_date_added":null,"published":"2007-09-05"},{"cvss_score":10,"headline":"Missing authorization in n/a","id":"CVE-2000-0514","kev_date_added":null,"published":"2000-10-13"},{"cvss_score":9.8,"headline":"Memory corruption in krb5 1.5","id":"CVE-2017-15088","kev_date_added":null,"published":"2017-11-23"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote authenticated users can forge Kerberos signatures due to weak RC4 key derivation, potentially gaining privileges.","url":"https://insights.sbomify.com/CVE-2010-4020/"}
