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-2011-1527 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-2011-1527/ (Markdown: https://insights.sbomify.com/CVE-2011-1527/index.md)","id":"CVE-2011-1527","markdown":"https://insights.sbomify.com/CVE-2011-1527/index.md","name":"CVE-2011-1527","record":{"aliases":["DEBIAN-CVE-2011-1527","GHSA-848m-2rw5-f2f2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Kerberos KDC","requires_auth":"none","summary":"Remote attackers can crash the Kerberos KDC daemon via a crafted kinit request when the LDAP backend is enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos_5","vendor":"mit"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The kdb_ldap plugin in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a kinit operation with incorrect string case for the realm, related to the is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal, and process_as_req functions.","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":"Null dereference in n/a","id":"CVE-2011-1527","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-1528"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2011-1526"},"products":["n/a"],"published":"2011-10-20","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 crash the Kerberos KDC daemon via a crafted kinit request when the LDAP backend is enabled.","url":"https://insights.sbomify.com/CVE-2011-1527/"}
