CVSS: 9.8EPSS: 1%CPEs: 1EXPL: 1CVE-2021-38540 – Apache Airflow: Variable Import endpoint missed authentication check
https://notcve.org/view.php?id=CVE-2021-38540
The variable import endpoint was not protected by authentication in Airflow >=2.0.0, <2.1.3. This allowed unauthenticated users to hit that endpoint to add/modify Airflow variables used in DAGs, potentially resulting in a denial of service, information disclosure or remote code execution. This issue affects Apache Airflow >=2.0.0, <2.1.3. El endpoint de importación de variables no estaba protegido por autenticación en Airflow versiones posteriores a 2.0.0 incluyéndola, versiones anteriores a 2.1.3. Esto permitía a usuarios no autenticados acceder a ese endpoint para añadir y modificar las variables de Airflow usadas en los DAG, resultando en una denegación de servicio, una divulgación de información o una ejecución de código remota. • https://github.com/Captain-v-hook/PoC-for-CVE-2021-38540- https://lists.apache.org/thread.html/rac2ed9118f64733e47b4f1e82ddc8c8020774698f13328ca742b03a2%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/rb34c3dd1a815456355217eef34060789f771b6f77c3a3dec77de2064%40%3Cusers.airflow.apache.org%3E • CWE-269: Improper Privilege Management CWE-306: Missing Authentication for Critical Function •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-35936 – No Authentication on Logging Server
https://notcve.org/view.php?id=CVE-2021-35936
If remote logging is not used, the worker (in the case of CeleryExecutor) or the scheduler (in the case of LocalExecutor) runs a Flask logging server and is listening on a specific port and also binds on 0.0.0.0 by default. This logging server had no authentication and allows reading log files of DAG jobs. This issue affects Apache Airflow < 2.1.2. Si no es usado el registro remoto, el trabajador (en el caso de CeleryExecutor) o el planificador (en el caso de LocalExecutor) ejecuta un servidor de registro Flask y está escuchando en un puerto específico y también se vincula en 0.0.0.0 por defecto. Este servidor de registro no presenta autenticación y permite leer los archivos de registro de los trabajos DAG. • https://lists.apache.org/thread.html/r53d6bd7b0a66f92ddaf1313282f10fec802e71246606dd30c16536df%40%3Cusers.airflow.apache.org%3E • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-306: Missing Authentication for Critical Function •
CVSS: 5.3EPSS: 1%CPEs: 2EXPL: 0CVE-2021-29621 – Observable Response Discrepancy in Flask-AppBuilder
https://notcve.org/view.php?id=CVE-2021-29621
Flask-AppBuilder is a development framework, built on top of Flask. User enumeration in database authentication in Flask-AppBuilder <= 3.2.3. Allows for a non authenticated user to enumerate existing accounts by timing the response time from the server when you are logging in. Upgrade to version 3.3.0 or higher to resolve. Flask-AppBuilder es un marco de desarrollo, construido sobre Flask. • https://github.com/dpgaspar/Flask-AppBuilder/commit/780bd0e8fbf2d36ada52edb769477e0a4edae580 https://github.com/dpgaspar/Flask-AppBuilder/security/advisories/GHSA-434h-p4gx-jm89 https://lists.apache.org/thread.html/r466759f377651f0a690475d5a52564d0e786e82c08d5a5730a4f8352%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r5b754118ba4e996adf03863705d34168bffec202da5c6bdc9bf3add5%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r91067f953906d93aaa1c69fe2b5472754019cc6bd4f1ba81349d62a0%40%3Ccommits.airflow.apache.org%3E https://pypi.org/project/ • CWE-203: Observable Discrepancy •
CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 0CVE-2021-28359 – Apache Airflow Reflected XSS via Origin Query Argument in URL
https://notcve.org/view.php?id=CVE-2021-28359
The "origin" parameter passed to some of the endpoints like '/trigger' was vulnerable to XSS exploit. This issue affects Apache Airflow versions <1.10.15 in 1.x series and affects 2.0.0 and 2.0.1 and 2.x series. This is the same as CVE-2020-13944 & CVE-2020-17515 but the implemented fix did not fix the issue completely. Update to Airflow 1.10.15 or 2.0.2. Please also update your Python version to the latest available PATCH releases of the installed MINOR versions, example update to Python 3.6.13 if you are on Python 3.6. • https://lists.apache.org/thread.html/ra8ce70088ba291f358e077cafdb14d174b7a1ce9a9d86d1b332d6367%40%3Cusers.airflow.apache.org%3E https://lists.apache.org/thread.html/rc005f4de9d9b0ba943ceb8ff5a21a5c6ff8a9df52632476698d99432%40%3Cannounce.apache.org%3E • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-26697 – Apache Airflow: Lineage API endpoint for Experimental API missed authentication check
https://notcve.org/view.php?id=CVE-2021-26697
The lineage endpoint of the deprecated Experimental API was not protected by authentication in Airflow 2.0.0. This allowed unauthenticated users to hit that endpoint. This is low-severity issue as the attacker needs to be aware of certain parameters to pass to that endpoint and even after can just get some metadata about a DAG and a Task. This issue affects Apache Airflow 2.0.0. El endpoint lineage de la API Experimental obsoleta no estaba protegido por autenticación en Airflow versión 2.0.0. • http://www.openwall.com/lists/oss-security/2021/02/17/2 https://lists.apache.org/thread.html/r36111262a59219a3e2704c71e97cf84937dae5ba7a1da99499e5d8f9%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/re21fec81baea7a6d73b0b5d31efd07cc02c61f832e297f65bb19b519%40%3Cdev.airflow.apache.org%3E https://lists.apache.org/thread.html/re21fec81baea7a6d73b0b5d31efd07cc02c61f832e297f65bb19b519%40%3Cusers.airflow.apache.org%3E • CWE-269: Improper Privilege Management CWE-306: Missing Authentication for Critical Function •
