Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) 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.


2) 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.


3) 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.



4) Improper input validation (CVE-ID: CVE-2019-14379)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Core (jackson-databind) component in Primavera Unifier. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.


5) 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.


6) 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.
