CVSS: 5.3EPSS: 10%CPEs: 42EXPL: 0CVE-2021-33037 – Incorrect Transfer-Encoding handling with HTTP/1.0
https://notcve.org/view.php?id=CVE-2021-33037
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding. Apache Tomcat versiones 10.0.0-M1 hasta 10.0.6, versiones 9.0.0.M1 hasta 9.0.46 y versiones 8.5.0 hasta 8.5.66, no analizaban correctamente el encabezado de petición HTTP transfer-encoding en algunas circunstancias, conllevando a la posibilidad de contrabando de peticiones cuando se usaba con un proxy inverso. Específicamente: - Tomcat ignoraba incorrectamente el encabezado de codificación de transferencia si el cliente declaraba que sólo aceptaría una respuesta HTTP/1.0; - Tomcat honraba la codificación de identificación; y - Tomcat no se aseguraba de que, si estaba presente, la codificación en trozos fuera la codificación final • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r290aee55b72811fd19e75ac80f6143716c079170c5671b96932ed44b%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r40f921575aee8d7d34e53182f862c45cbb8f3d898c9d4e865c2ec262%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r612a79269b0d5e5780c62dfd34286a8037232fec0bc6f1a7e60c9381%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/rc6ef52453bb996a98cb45442871a1db56b7c349939e45d829bf9ae37%40%3Ccommits.tomee.apache.org%3E https:/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 7.5EPSS: 1%CPEs: 17EXPL: 0CVE-2021-30639 – DoS after non-blocking IO error
https://notcve.org/view.php?id=CVE-2021-30639
A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r79a7c019712b39aedf7cf4da9276d80610f04441b2a4f6506cb2daaf%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r79a7c019712b39aedf7cf4da9276d80610f04441b2a4f6506cb2daaf%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/rd84fae1f474597bdf358f5bdc0a5c453c507bd527b83e8be6b5ea3f4%40%3Cannounce.tomcat.apache.org%3E https://security.gentoo.org/glsa/202208-34 https://security.netapp.com/advisory/ntap-20210827-0007 https://www. • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2021-23890
Information leak vulnerability in the Agent Handler of McAfee ePolicy Orchestrator (ePO) prior to 5.10 Update 10 allows an unauthenticated user to download McAfee product packages (specifically McAfee Agent) available in ePO repository and install them on their own machines to have it managed and then in turn get policy details from the ePO server. This can only happen when the ePO Agent Handler is installed in a Demilitarized Zone (DMZ) to service machines not connected to the network through a VPN. Una vulnerabilidad de filtrado de información en el controlador de agentes de McAfee ePolicy Orchestrator (ePO) versiones anteriores a 5.10 Update 10, permite a un usuario no autenticado descargar paquetes de productos de McAfee (específicamente McAfee Agent) disponibles en el repositorio de ePO e instalarlos en sus propios equipos para administrarlos y luego a su vez, obtener detalles de la política del servidor de ePO. Esto solo puede suceder cuando el controlador de agentes de ePO está instalado en una zona desmilitarizada (DMZ) para dar servicio a los equipos que no están conectados a la red mediante una VPN. • https://kc.mcafee.com/corporate/index?page=content&id=SB10352 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
