Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU21580
Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2019-16942
CWE-ID:
Exploit availability:
DescriptionThe 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.

CVSSv3.1:
CVE-ID: CVE-2019-16943
CWE-ID:
Exploit availability:
DescriptionThe 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.

EUVDB-ID: #VU21750
Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2019-17531
CWE-ID:
Exploit availability:
DescriptionThe 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.
