Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) 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.
5) Unsafe reflection (CVE-ID: CVE-2019-10174)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to Infinispan uses an insecure invokeAccessibly method from ReflectionUtil class that allows to invoke other private methods. A local user can abuse this functionality to execute arbitrary code on the system with privileges of Infinispan process.
