It was discovered that the Role Based Access Control (RBAC) implementation did not sufficiently verify all authorization conditions required by the Maintainer role to perform certain administrative actions. An authenticated user with the Maintainer role can use this flaw to add, modify or undefine a limited set of attributes and their values which otherwise cannot be written to.

IssueDescription:

It was found that the default context parameters as provided to RESTEasy deployments by JBoss EAP did not explicitly disable external entity expansion for RESTEasy. A remote attacker could use this flaw to perform XML External Entity (XXE) attacks on RESTEasy applications accepting XML input.

It was identified that security auditing provided by JBossSX/PicketBox logged sensitive information into a world readable audit.log file. This information could be used by a local attacker to gain otherwise protected information about user sessions etc.

IssueDescription:

It was identified that PicketBox/JBossSX allowed any deployed application to alter or read the underlying application server configuration and state without any authorization checks. An attacker able to deploy applications could use this flaw to circumvent security constraints applied to other applications deployed on the same system, disclose privileged information, and in certain cases allow arbitrary code execution.
