Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2019-17531)

The vulnerability allows a remote attacker to compromise the affected software.

The vulnerability exists due to a Polymorphic Typing in jackson-databind when processing JSON requests. A remote attacker can send specially crafted JSON data to JNDI service and execute a malicious payload.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the apache-log4j-extra (version 1.2.x) jar in the classpath.


2) Input validation error (CVE-ID: CVE-2019-17267)

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue within the net.sf.ehcache.hibernate.EhcacheJtaTransactionManagerLookup component. A remote attacker can execute arbitrary code on he system.


3) Input validation error (CVE-ID: CVE-2019-16943)

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue when processing JSON requests  within the com.p6spy.engine.spy.P6DataSource component. A remote attacker can send specially crafted JSON data to an RMI service endpoint and execute arbitrary code on he system.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint to send requests to.


4) Input validation error (CVE-ID: CVE-2019-16942)

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue when processing JSON requests  within the org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSourc components. A remote attacker can send specially crafted JSON data to an RMI service endpoint and execute arbitrary code on he system.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to send requests to.


5) Information disclosure (CVE-ID: CVE-2019-16335)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue in the "com.zaxxer.hikari.HikariDataSource". A remote attacker can gain unauthorized access to sensitive information on the system.


6) Information disclosure (CVE-ID: CVE-2019-14540)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue in the "com.zaxxer.hikari.HikariConfig". A remote attacker can gain unauthorized access to sensitive information on the system.


7) Information disclosure (CVE-ID: CVE-2019-12086)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the mysql-connector-java jar in the classpath. A remote attacker can send a specially crafted JSON message and read arbitrary local files on the server due to the missing "com.mysql.cj.jdbc.admin.MiniAdmin" validation.


8) Information disclosure (CVE-ID: CVE-2019-14439)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the logback jar in the classpath. A remote attacker can send a specially crafted JSON message and gain unauthorized access to sensitive information on the system.


9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14379)

The vulnerability allows a remote attacker to execute arbitrary code on a targeted system.

The vulnerability exists due to the "SubTypeValidator.java" file mishandles default typing when Ehcache is used. A remote attacker can send a request that submits malicious input to the targeted system and execute arbitrary code.


10) Deserialization of Untrusted Data (CVE-ID: CVE-2019-12384)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to software allows the logback-core class to process polymorphic deserialization. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


11) Information disclosure (CVE-ID: CVE-2019-12814)

The vulnerability allows a remote attacker to access sensitive information on a targeted system.

The vulnerability exist due to a polymorphic typing issue when Default Typing is enabled. A remote attacker can send a crafted JSON message that submits malicious input and gain access to sensitive information on the targeted system.
