Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2019-10173)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data passed in XML or JSON formats within the xstream API. 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.
2) Improper input validation (CVE-ID: CVE-2019-10219)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Web Services (JBoss Enterprise Application Platform) component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
3) 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.
4) Deserialization of Untrusted Data (CVE-ID: CVE-2019-14892)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data of a malicious object using commons-configuration 1 and 2 JNDI classes. 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.
5) Deserialization of Untrusted Data (CVE-ID: CVE-2019-14893)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data of malicious objects using the xalan JNDI gadget when used in conjunction with polymorphic type handling methods such as "enableDefaultTyping()" or when @JsonTypeInfo is using "Id.CLASS" or "Id.MINIMAL_CLASS" or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. 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.
6) 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.
7) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-16869)
The vulnerability allows a remote attacker to perform HTTP request smuggling attack.
The vulnerability exists due to improper input validation when processing a whitespace before the colon in HTTP headers (e.g. "Transfer-Encoding : chunked"). A remote attacker can send a specially crafted HTTP request and perform HTTP request smuggling attack.
8) 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.
9) 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.
10) 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.
11) 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.
12) Input validation error (CVE-ID: CVE-2013-7285)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input passed in XML and JSON formats to the Xstream API. A remote attacker can send specially crafted request to the affected application and execute arbitrary code on the target system.
