Permissions, Privileges, and Access Controls

CVE-2019-3894

High
8.8/10

Summary

It was discovered that the ElytronManagedThread in Wildfly's Elytron subsystem in versions from 11.0.0.Beta1 to 16.0.0.Beta1 stores a SecurityIdentity to run the thread as. These threads do not necessarily terminate if the keep alive time has not expired. This could allow a shared thread to use the wrong security identity when executing.

CWE-264 - Permissions Privileges and Access Controls

CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
