CVE-2020-25640
Description
A flaw was found in wildfly. JMS passwords are logged by the resource adaptor in plain text at the warning level when a connection error occurs allowing any user that has access to the log to gain access to this sensitive information. The highest threat from this vulnerability is to data confidentiality.
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).

Red Hat CVSS v3 Score Explanation
Red Hat Products does not enable the some conditions required for this flaw, and as such have a base score that differs from NVD's base evaluation, AC:L/PR:N -> AC:H/PR:L, the potential attacker has to go through various complexities for purposefully generating the error message in the log files as the potential attacker is heavily dependent on the connection to be lost or killed by an entity over which the attacker does not have control. The vulnerability is only present in the generic JMS resource adapter whose primary purpose is to be used to connect to messaging brokers which do not have its own resource adapter adding to the complexity of the occurrence of the issue. Also a potential attacker will need some level of access too the host server or access to the admin console to check the log entries. The resulting score and impact are 5.3/Moderate.
