CVE-2020-11998
https://notcve.org/view.php?id=CVE-2020-11998
A regression has been introduced in the commit preventing JMX re-bind. By passing an empty environment map to RMIConnectorServer, instead of the map that contains the authentication credentials, it leaves ActiveMQ open to the following attack: https://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html "A remote client could create a javax.management.loading.MLet MBean and use it to create new MBeans from arbitrary URLs, at least if there is no security manager. In other words, a rogue remote client could make your Java application execute arbitrary code." Mitigation: Upgrade to Apache ActiveMQ 5.15.13 Se ha introducido una regresión en el commit que evita que JMX vuelva a vincularse. Al pasar un mapa de entorno vacío hacia RMIConnectorServer, en lugar del mapa que contiene las credenciales de autenticación, deja ActiveMQ abierto al siguiente ataque: https://docs.oracle.com/javase/8/docs/technotes/guides/management/ agent.html. " Un cliente remoto podría crear un MBean javax.management.loading.MLet y usarlo para crear nuevos MBeans a partir de URL arbitrarias, al menos si no existe un administrador de seguridad. • http://activemq.apache.org/security-advisories.data/CVE-2020-11998-announcement.txt https://lists.apache.org/thread.html/r946488fb942fd35c6a6e0359f52504a558ed438574a8f14d36d7dcd7%40%3Ccommits.activemq.apache.org%3E https://lists.apache.org/thread.html/rb2fd3bf2dce042e0ab3f3c94c4767c96bb2e7e6737624d63162df36d%40%3Ccommits.activemq.apache.org%3E https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security- •
CVE-2020-13920 – activemq: improper authentication allows MITM attack
https://notcve.org/view.php?id=CVE-2020-13920
Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server to the "jmxrmi" entry. It is possible to connect to the registry without authentication and call the rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the original, and bound that, he effectively becomes a man in the middle and is able to intercept the credentials when an user connects. Upgrade to Apache ActiveMQ 5.15.12. Apache ActiveMQ usa la función LocateRegistry.createRegistry() para crear el registro RMI de JMX y vincular el servidor a la entrada "jmxrmi". • http://activemq.apache.org/security-advisories.data/CVE-2020-13920-announcement.txt https://lists.apache.org/thread.html/r946488fb942fd35c6a6e0359f52504a558ed438574a8f14d36d7dcd7%40%3Ccommits.activemq.apache.org%3E https://lists.apache.org/thread.html/rb2fd3bf2dce042e0ab3f3c94c4767c96bb2e7e6737624d63162df36d%40%3Ccommits.activemq.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/10/msg00013.html https://lists.debian.org/debian-lts-announce/2023/11/msg00013.html https://www.oracle.com/security-alerts/cpuoct2020.html https:/& • CWE-287: Improper Authentication CWE-306: Missing Authentication for Critical Function •

CVE-2020-8622 – A truncated TSIG response can lead to an assertion failure
https://notcve.org/view.php?id=CVE-2020-8622
In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit. En BIND versiones 9.0.0 -) 9.11.21, 9.12.0 -) 9.16.5, 9.17.0 -) 9.17.3, también afecta a versiones 9.9.3-S1 -) 9.11.21-S1 de BIND 9 Supported Preview Edition, un atacante sobre la ruta de la red para una petición firmada por TSIG, u operando el servidor que recibe la petición firmada por TSIG, podría enviar una respuesta truncada a esa petición, desencadenando un fallo de aserción y causando que el servidor salga. Alternativamente, un atacante fuera de la ruta tendría que adivinar correctamente cuándo fue enviada una petición firmada por TSIG, junto con otras características del paquete y mensaje, y falsificar una respuesta truncada para desencadenar un fallo de aserción, causando la salida del servidor. A flaw was found in bind. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html https://kb.isc.org/docs/cve-2020-8622 https://lists.debian.org/debian-lts-announce/2020/08/msg00053.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DQN62GBMCIC5AY4KYADGXNKVY6AJKSJE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZKAMJZXR66P6S5LEU4SN7USSNCWTXEXP https://security. • CWE-400: Uncontrolled Resource Consumption CWE-617: Reachable Assertion •
