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-2015-2694 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-2015-2694/ (Markdown: https://insights.sbomify.com/CVE-2015-2694/index.md)","id":"CVE-2015-2694","markdown":"https://insights.sbomify.com/CVE-2015-2694/index.md","name":"CVE-2015-2694","record":{"aliases":["DEBIAN-CVE-2015-2694","GHSA-6h2g-5cjr-jj97","UBUNTU-CVE-2015-2694"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kerberos authentication server","requires_auth":"none","summary":"Remote attackers can bypass Kerberos preauthentication requirements by sending empty data or arbitrary realm names, potentially gaining unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos_5","vendor":"mit"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The kdcpreauth modules in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.2 do not properly track whether a client's request has been validated, which allows remote attackers to bypass an intended preauthentication requirement by providing (1) zero bytes of data or (2) an arbitrary realm name, related to plugins/preauth/otp/main.c and plugins/preauth/pkinit/pkinit_srv.c.","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":"Auth bypass in n/a","id":"CVE-2015-2694","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"auth_bypass","year":"2015"},"n_packages":0,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-2695"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2015-2692"},"products":["n/a"],"published":"2015-05-25","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can bypass Kerberos preauthentication requirements by sending empty data or arbitrary realm names, potentially gaining unauthorized access.","url":"https://insights.sbomify.com/CVE-2015-2694/"}
