Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-44145 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.nifi:nifi (Maven): affected all versions; fixed in 1.15.1\n- org.apache.nifi:nifi (Maven): affected all versions; fixed in 1.15.1\n- nifi (Bitnami): affected from 0.1.0; fixed in 1.15.1\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-2021-44145/ (Markdown: https://insights.sbomify.com/CVE-2021-44145/index.md)","id":"CVE-2021-44145","markdown":"https://insights.sbomify.com/CVE-2021-44145/index.md","name":"CVE-2021-44145","record":{"aliases":["BIT-nifi-2021-44145","GHSA-rq96-qhc5-vm4r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache NiFi","requires_auth":"low_privilege","summary":"An authenticated user can exploit an XXE vulnerability in the TransformXML processor to reveal sensitive information.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nifi","vendor":"apache"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"In the TransformXML processor of Apache NiFi before 1.15.1 an authenticated user could configure an XSLT file which, if it included malicious external entity calls, may reveal sensitive information.","ecosystems":["Bitnami","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":"Apache NiFi information disclosure by XXE","id":"CVE-2021-44145","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:nifi","products":["apache:nifi"],"type":"xxe","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"XML external entity in n/a","id":"CVE-2021-44147"},"packages":[{"ecosystem":"Bitnami","fixed":["1.15.1"],"introduced":["0.1.0"],"last_affected":[],"package":"nifi","purl":"pkg:bitnami/nifi","source":"BIT-nifi-2021-44145"},{"ecosystem":"Maven","fixed":["1.15.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.nifi:nifi","purl":null,"source":"GHSA-rq96-qhc5-vm4r"},{"ecosystem":"Maven","fixed":["1.15.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.nifi:nifi","purl":"pkg:maven/org.apache.nifi/nifi","source":"GHSA-rq96-qhc5-vm4r"}],"prev":{"headline":"Asterix Heap-based Buffer Overflow","id":"CVE-2021-44144"},"products":["Apache NiFi"],"published":"2021-12-17","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Apache NiFi","id":"CVE-2018-1309","kev_date_added":null,"published":"2018-05-23"},{"cvss_score":9.8,"headline":"Apache NiFi XSS issue in context path handling","id":"CVE-2017-15697","kev_date_added":null,"published":"2018-01-23"},{"cvss_score":9.8,"headline":"Injection in Apache NiFi","id":"CVE-2017-5636","kev_date_added":null,"published":"2017-10-19"},{"cvss_score":8.8,"headline":"Apache NiFi: Uncontrolled Resource Consumption through Decompression of HTTP Requests","id":"CVE-2026-68981","kev_date_added":null,"published":"2026-08-03"},{"cvss_score":8.8,"headline":"Apache NiFi: Potential Code Injection with Properties Referencing Remote Resources","id":"CVE-2023-36542","kev_date_added":null,"published":"2023-07-29"},{"cvss_score":8.8,"headline":"Apache NiFi: Potential Code Injection with Database Services using H2","id":"CVE-2023-34468","kev_date_added":null,"published":"2023-06-12"},{"cvss_score":8.8,"headline":"Improper Neutralization of Command Elements in Shell User Group Provider","id":"CVE-2022-33140","kev_date_added":null,"published":"2022-06-15"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-08-04","vendors":["Apache Software Foundation"]},"summary":"An authenticated user can exploit an XXE vulnerability in the TransformXML processor to reveal sensitive information.","url":"https://insights.sbomify.com/CVE-2021-44145/"}
