CVSS: 7.0EPSS: 91%CPEs: 77EXPL: 12CVE-2020-9484 – tomcat: deserialization flaw in session persistence storage leading to RCE
https://notcve.org/view.php?id=CVE-2020-9484
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. Cuando se usa Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M4, 9.0.0.M1 hasta 9.0.34, 8.5.0 hasta 8.5.54 y 7.0.0 hasta 7.0. 103, si a) un atacante es capaz de controlar el contenido y el nombre de un archivo en el servidor; y b) el servidor está configurado para usar el PersistenceManager con un FileStore; y c) el PersistenceManager está configurado con sessionAttributeValueClassNameFilter="null" (el valor predeterminado a menos que se utilice un SecurityManager) o un filtro lo suficientemente laxo como para permitir que el objeto proporcionado por el atacante sea deserializado; y d) el atacante conoce la ruta relativa del archivo desde la ubicación de almacenamiento usada por FileStore hasta el archivo sobre el que el atacante presenta control; entonces, mediante una petición específicamente diseñada, el atacante podrá ser capaz de desencadenar una ejecución de código remota mediante la deserialización del archivo bajo su control. Tome en cuenta que todas las condiciones desde la a) hasta la d) deben cumplirse para que el ataque tenga éxito. A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. • https://github.com/masahiro331/CVE-2020-9484 https://github.com/IdealDreamLast/CVE-2020-9484 https://github.com/osamahamad/CVE-2020-9484-Mass-Scan https://github.com/PenTestical/CVE-2020-9484 https://github.com/AssassinUKG/CVE-2020-9484 https://github.com/RepublicR0K/CVE-2020-9484 https://github.com/anjai94/CVE-2020-9484-exploit https://github.com/ColdFusionX/CVE-2020-9484 https://github.com/VICXOR/CVE-2020-9484 https://github.com/seanachao/CVE-2020-9484 https://github& • CWE-502: Deserialization of Untrusted Data •
CVSS: 9.8EPSS: 97%CPEs: 38EXPL: 18CVE-2020-1938 – Apache Tomcat Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2020-1938
When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. • https://www.exploit-db.com/exploits/49039 https://www.exploit-db.com/exploits/48143 https://github.com/sgdream/CVE-2020-1938 https://github.com/xindongzhuaizhuai/CVE-2020-1938 https://github.com/laolisafe/CVE-2020-1938 https://github.com/sv3nbeast/CVE-2020-1938-Tomact-file_include-file_read https://github.com/fairyming/CVE-2020-1938 https://github.com/dacade/CVE-2020-1938 https://github.com/Hancheng-Lei/Hacking-Vulnerability-CVE-2020-1938-Ghostcat https://github.com/w4fz5uck5& • CWE-285: Improper Authorization •

https://notcve.org/view.php?id=CVE-2019-10086
In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean. En Apache Commons Beanutils 1.9.2, se agregó una clase especial BeanIntrospector que permite suprimir la capacidad de un atacante para acceder al cargador de clases a través de la propiedad de clase disponible en todos los objetos Java. Sin embargo, no se esta usando esta característica por defecto de PropertyUtilsBean. A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00007.html http://mail-archives.apache.org/mod_mbox/www-announce/201908.mbox/%3cC628798F-315D-4428-8CB1-4ED1ECC958E4%40apache.org%3e https://access.redhat.com/errata/RHSA-2019:4317 https://access.redhat.com/errata/RHSA-2020:0057 https://access.redhat.com/errata/RHSA-2020:0194 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 • CWE-502: Deserialization of Untrusted Data •
CVSS: 7.5EPSS: 0%CPEs: 114EXPL: 0CVE-2018-15756 – DoS Attack via Range Requests
https://notcve.org/view.php?id=CVE-2018-15756
Spring Framework, version 5.1, versions 5.0.x prior to 5.0.10, versions 4.3.x prior to 4.3.20, and older unsupported versions on the 4.2.x branch provide support for range requests when serving static resources through the ResourceHttpRequestHandler, or starting in 5.0 when an annotated controller returns an org.springframework.core.io.Resource. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack. This vulnerability affects applications that depend on either spring-webmvc or spring-webflux. Such applications must also have a registration for serving static resources (e.g. JS, CSS, images, and others), or have an annotated controller that returns an org.springframework.core.io.Resource. • http://www.securityfocus.com/bid/105703 https://lists.apache.org/thread.html/339fd112517e4873695b5115b96acdddbfc8f83b10598528d37c7d12%40%3Cissues.activemq.apache.org%3E https://lists.apache.org/thread.html/77886fec378ee6064debb1efb6b464a4a0173b2ff0d151ed86d3a228%40%3Cissues.activemq.apache.org%3E https://lists.apache.org/thread.html/7b156ee50ba3ecce87b33c06bf7a749d84ffee55e69bfb5eca88fcc3%40%3Cissues.activemq.apache.org%3E https://lists.apache.org/thread.html/8a1fe70534fc52ff5c9db5ac29c55657f802cbefd7e9d9850c7052bd%40%3Cissues.activemq.apache.org%3E https://lists.apache.org/ • CWE-20: Improper Input Validation •
