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 •

https://notcve.org/view.php?id=CVE-2019-16942
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling. Se descubrió un problema de escritura polimórfica en FasterXML jackson-databind versión 2.0.0 hasta 2.9.10. Cuando la Escritura Predeterminada está habilitada (tanto globalmente o para una propiedad específica) para un end point JSON expuesto externamente y el servicio posee el jar commons-dbcp (versión 1.4) en el classpath, y un atacante puede encontrar un end point de servicio RMI para acceder, es posible lograr que el servicio ejecute una carga maliciosa. • https://access.redhat.com/errata/RHSA-2019:3901 https://access.redhat.com/errata/RHSA-2020:0159 https://access.redhat.com/errata/RHSA-2020:0160 https://access.redhat.com/errata/RHSA-2020:0161 https://access.redhat.com/errata/RHSA-2020:0164 https://access.redhat.com/errata/RHSA-2020:0445 https://github.com/FasterXML/jackson-databind/issues/2478 https://issues.apache.org/jira/browse/GEODE-7255 https://lists.apache.org/thread.html/519eb0fd45642dcecd9ff74cb3e71c20a4753f7d82e2f07864b5108f%40%3Cdev. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-502: Deserialization of Untrusted Data •

Vulnerability in the Application Express component of Oracle Database Server. Supported versions that are affected are 5.1 and 18.2. Easily exploitable vulnerability allows low privileged attacker having Valid Account privilege with network access via HTTP to compromise Application Express. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Application Express, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Application Express accessible data as well as unauthorized read access to a subset of Application Express accessible data. • http://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html •

An issue is present in Apache ZooKeeper 1.0.0 to 3.4.13 and 3.5.0-alpha to 3.5.4-beta. ZooKeeper’s getACL() command doesn’t check any permission when retrieves the ACLs of the requested node and returns all information contained in the ACL Id field as plaintext string. DigestAuthenticationProvider overloads the Id field with the hash value that is used for user authentication. As a consequence, if Digest Authentication is in use, the unsalted hash value will be disclosed by getACL() request for unauthenticated or unprivileged users. Hay un problema presente en Apache ZooKeeper 1.0.0 a 3.4.13 y 3.5.0-alpha a 3.5.4-beta. • http://www.securityfocus.com/bid/108427 https://access.redhat.com/errata/RHSA-2019:3140 https://access.redhat.com/errata/RHSA-2019:3892 https://access.redhat.com/errata/RHSA-2019:4352 https://issues.apache.org/jira/browse/ZOOKEEPER-1392 https://lists.apache.org/thread.html/053d9ce4d579b02203db18545fee5e33f35f2932885459b74d1e4272%40%3Cissues.activemq.apache.org%3E https://lists.apache.org/thread.html/519eb0fd45642dcecd9ff74cb3e71c20a4753f7d82e2f07864b5108f%40%3Cdev.drill.apache.org%3E https://lists.apache.org/thread.html&#x • CWE-732: Incorrect Permission Assignment for Critical Resource CWE-862: Missing Authorization •
