Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40273 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache-airflow (PyPI): affected all versions; fixed in 2.7.0rc2\n- apache-airflow (PyPI): affected all versions; fixed in 2.7.0rc2\n- apache-airflow (PyPI): affected all versions; fixed in 2.7.1rc1\n- airflow (Bitnami): affected all versions; fixed in 2.7.1\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-2023-40273/ (Markdown: https://insights.sbomify.com/CVE-2023-40273/index.md)","id":"CVE-2023-40273","markdown":"https://insights.sbomify.com/CVE-2023-40273/index.md","name":"CVE-2023-40273","record":{"aliases":["BIT-airflow-2023-40273","GHSA-pm87-24wq-r8w9","PYSEC-2023-158"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Airflow","requires_auth":"low_privilege","summary":"Authenticated users retain access after password reset due to session fixation, bypassing intended security controls in Apache Airflow.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"airflow","vendor":"apache"}],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"The session fixation vulnerability allowed the authenticated user to continue accessing Airflow webserver even after the password of the user has been reset by the admin - up until the expiry of the session of the user. Other than manually cleaning the session database (for database session backend), or changing the secure_key and restarting the webserver, there were no mechanisms to force-logout the user (and all other users with that).\n\nWith this fix implemented, when using the database session backend, the existing sessions of the user are invalidated when the password of the user is reset. When using the securecookie session backend, the sessions are NOT invalidated and still require changing the secure key and restarting the webserver (and logging out all other users), but the user resetting the password is informed about it with a flash message warning displayed in the UI. Documentation is also updated explaining this behaviour.\n\nUsers of Apache Airflow are advised to upgrade to version 2.7.0 or newer to mitigate the risk associated with this vulnerability.","ecosystems":["Bitnami","PyPI"],"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":"Session fixation in Apache Airflow web interface","id":"CVE-2023-40273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:airflow","products":["apache:airflow"],"type":"security_feature_bypass","year":"2023"},"n_packages":4,"n_references":3,"next":{"headline":"zola Path Traversal vulnerability","id":"CVE-2023-40274"},"packages":[{"ecosystem":"Bitnami","fixed":["2.7.1"],"introduced":["0"],"last_affected":[],"package":"airflow","purl":"pkg:bitnami/airflow","source":"BIT-airflow-2023-40273"},{"ecosystem":"PyPI","fixed":["2.7.0rc2"],"introduced":["0"],"last_affected":[],"package":"apache-airflow","purl":null,"source":"GHSA-pm87-24wq-r8w9"},{"ecosystem":"PyPI","fixed":["2.7.0rc2"],"introduced":["0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"GHSA-pm87-24wq-r8w9"},{"ecosystem":"PyPI","fixed":["2.7.1rc1"],"introduced":["0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"PYSEC-2023-158"}],"prev":{"headline":"Apache Airflow Spark Provider Arbitrary File Read via JDBC","id":"CVE-2023-40272"},"products":["Apache Airflow"],"published":"2023-08-23","related":[{"cvss_score":9.8,"headline":"Apache Airflow's Experimental API Authentication Bypass","id":"CVE-2020-13927","kev_date_added":"2022-01-18","published":"2020-11-10"},{"cvss_score":8.8,"headline":"Apache Airflow Command Injection","id":"CVE-2020-11978","kev_date_added":"2022-01-18","published":"2020-07-16"},{"cvss_score":9.8,"headline":"Apache Airflow: DAG author RCE on webserver via unrestricted import_string() in BaseSerialization.deserialize()","id":"CVE-2026-33264","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":9.8,"headline":"Apache Airflow: Privilege escalation using airflow logs","id":"CVE-2023-25754","kev_date_added":null,"published":"2023-05-08"},{"cvss_score":9.8,"headline":"Apache Airflow, Apache Airflow MySQL Provider: Arbitrary file read via MySQL provider in Apache Airflow","id":"CVE-2023-22884","kev_date_added":null,"published":"2023-01-21"},{"cvss_score":9.8,"headline":"Apache Airflow Pinot provider allowed Command Injection","id":"CVE-2022-38649","kev_date_added":null,"published":"2022-11-22"},{"cvss_score":9.8,"headline":"Apache Airlfow Pig Provider RCE","id":"CVE-2022-40189","kev_date_added":null,"published":"2022-11-22"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-27","vendors":["Apache Software Foundation"]},"summary":"Authenticated users retain access after password reset due to session fixation, bypassing intended security controls in Apache Airflow.","url":"https://insights.sbomify.com/CVE-2023-40273/"}
