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-2012-4449 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.hadoop:hadoop-client (Maven): affected all versions; fixed in 0.23.4\n- org.apache.hadoop:hadoop-client (Maven): affected all versions; fixed in 0.23.4\n- org.apache.hadoop:hadoop-client (Maven): affected from 1.0.0; fixed in 1.0.4\n- org.apache.hadoop:hadoop-client (Maven): affected from 1.0.0; fixed in 1.0.4\n- org.apache.hadoop:hadoop-client (Maven): affected from 2.0.0; fixed in 2.0.2\n- org.apache.hadoop:hadoop-client (Maven): affected from 2.0.0; fixed in 2.0.2\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-2012-4449/ (Markdown: https://insights.sbomify.com/CVE-2012-4449/index.md)","id":"CVE-2012-4449","markdown":"https://insights.sbomify.com/CVE-2012-4449/index.md","name":"CVE-2012-4449","record":{"aliases":["GHSA-q46v-cj5v-hvg6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Hadoop distributed system","requires_auth":"none","summary":"Attackers can brute-force weak 20-bit token passwords in Hadoop Kerberos configurations to bypass security controls.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"hadoop","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Apache Hadoop before 0.23.4, 1.x before 1.0.4, and 2.x before 2.0.2 generate token passwords using a 20-bit secret when Kerberos security features are enabled, which makes it easier for context-dependent attackers to crack secret keys via a brute-force attack.","ecosystems":["Maven"],"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":"Use of a Broken or Risky Cryptographic Algorithm in Apache Hadoop","id":"CVE-2012-4449","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"weak_cryptography","year":"2012"},"n_packages":6,"n_references":2,"next":{"headline":"Auth bypass in n/a","id":"CVE-2012-4450"},"packages":[{"ecosystem":"Maven","fixed":["0.23.4"],"introduced":["0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":null,"source":"GHSA-q46v-cj5v-hvg6"},{"ecosystem":"Maven","fixed":["0.23.4"],"introduced":["0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":"pkg:maven/org.apache.hadoop/hadoop-client","source":"GHSA-q46v-cj5v-hvg6"},{"ecosystem":"Maven","fixed":["1.0.4"],"introduced":["1.0.0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":null,"source":"GHSA-q46v-cj5v-hvg6"},{"ecosystem":"Maven","fixed":["1.0.4"],"introduced":["1.0.0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":"pkg:maven/org.apache.hadoop/hadoop-client","source":"GHSA-q46v-cj5v-hvg6"},{"ecosystem":"Maven","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":null,"source":"GHSA-q46v-cj5v-hvg6"},{"ecosystem":"Maven","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.hadoop:hadoop-client","purl":"pkg:maven/org.apache.hadoop/hadoop-client","source":"GHSA-q46v-cj5v-hvg6"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2012-4448"},"products":["n/a"],"published":"2017-10-30","related":[{"cvss_score":9.8,"headline":"Command injection in org.apache.hadoop.fs.FileUtil.unTarUsingTar","id":"CVE-2022-25168","kev_date_added":null,"published":"2022-08-04"},{"cvss_score":9.8,"headline":"Heap buffer overflow in libhdfs native library","id":"CVE-2021-37404","kev_date_added":null,"published":"2022-06-13"},{"cvss_score":9.8,"headline":"Arbitrary file write in FileUtil#unpackEntries on Windows","id":"CVE-2022-26612","kev_date_added":null,"published":"2022-04-07"},{"cvss_score":9.8,"headline":"Improper Check for Unusual or Exceptional Conditions in Connect2id Nimbus JOSE+JWT","id":"CVE-2019-17195","kev_date_added":null,"published":"2019-10-15"},{"cvss_score":9.8,"headline":"Exposure of Sensitive Information in Hadoop","id":"CVE-2017-15718","kev_date_added":null,"published":"2018-01-24"},{"cvss_score":9.8,"headline":"Exposure of Sensitive Information to an Unauthorized Actor in Apache Hadoop","id":"CVE-2016-3086","kev_date_added":null,"published":"2017-09-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"Attackers can brute-force weak 20-bit token passwords in Hadoop Kerberos configurations to bypass security controls.","url":"https://insights.sbomify.com/CVE-2012-4449/"}
