CVE-2020-25638
Description
A flaw was found in hibernate-core in versions prior to and including 5.4.23.Final. A SQL injection in the implementation of the JPA Criteria API can permit unsanitized literals when a literal is used in the SQL comments of the query. This flaw could allow an attacker to access unauthorized information or possibly conduct further attacks. The highest threat from this vulnerability is to data confidentiality and integrity.
Statement
For Red Hat Process Automation Manager and Red Hat Decision Manager, the kie-server-ee7 zip is primarily for Weblogic/Websphere which is decided to stay on hibernate 5.1.x, it's not possible to make an upgrade to 5.3.x due to technical reasons. For this reason this fix is included only for kie-server-ee7. For this reason there are two components for RHPAM and RHDM.
Mitigation
Set hibernate.use_sql_comments to false, which is the default value, or use named parameters instead of literals. Please refer to details in https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#configurations-logging and https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#sql-query-parameters.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
