DocumentProvider in RESTEasy 2.3.7 and 3.0.9 does not configure the (1) external-general-entities or (2) external-parameter-entities features, which allows remote attackers to conduct XML external entity (XXE) attacks via unspecified vectors.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - DocumentProvider in RESTEasy 2.3.7 and 3.0.9 does not configure the (1) external-general-entities or (2)     external-parameter-entities features, which allows remote attackers to conduct XML external entity (XXE)     attacks via unspecified vectors. (CVE-2014-7839)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0218 advisory.

    Red Hat JBoss Enterprise Application Platform 6 is a platform for Java     applications based on JBoss Application Server 7.

    It was found that the RESTEasy DocumentProvider did not set the     external-parameter-entities and external-general-entities features     appropriately, thus allowing external entity expansion. A remote attacker     able to send XML requests to a RESTEasy endpoint could use this flaw to     read files accessible to the user running the application server, and     potentially perform other more advanced XML eXternal Entity (XXE) attacks.
    (CVE-2014-7839)

    It was discovered that the Role Based Access Control (RBAC) implementation     did not sufficiently verify all authorization conditions that are required     by the Maintainer role to perform certain administrative actions.
    An authenticated user with the Maintainer role could use this flaw to add,     modify, or undefine a limited set of attributes and their values, which     otherwise cannot be written to. (CVE-2014-7849)

    It was discovered that the JBoss Application Server (WildFly) JacORB     subsystem incorrectly assigned socket-binding-ref sensitivity     classification for the security-domain attribute. An authenticated user     with a role that has access to attributes with socket-binding-ref and not     security-domain-ref sensitivity classification could use this flaw to     access sensitive information present in the security-domain attribute.
    (CVE-2014-7853)

    It was found that when processing undefined security domains, the     org.jboss.security.plugins.mapping.JBossMappingManager implementation would     fall back to the default security domain if it was available. A user with     valid credentials in the defined default domain, with a role that is valid     in the expected application domain, could perform actions that were     otherwise not available to them. When using the SAML2 STS Login Module,     JBossMappingManager exposed this issue due to the PicketLink Trust     SecurityActions implementation using a hardcoded default value when     defining the context. (CVE-2014-7827)

    It was discovered that under specific conditions the conversation state     information stored in a thread-local variable was not sanitized correctly     when the conversation ended. This could lead to a race condition that could     potentially expose sensitive information from a previous conversation to     the current conversation. (CVE-2014-8122)

    Red Hat would like to thank Rune Steinseth of JProfessionals for reporting     the CVE-2014-8122 issue. The CVE-2014-7849 and CVE-2014-7853 issues were     discovered by Darran Lofthouse of the Red Hat JBoss Enterprise Application     Platform Team, and the CVE-2014-7827 issue was discovered by Ondra Lukas of     the Red Hat Quality Engineering Team.

    This release serves as a replacement for Red Hat JBoss Enterprise     Application Platform 6.3.2, and includes bug fixes and enhancements.
    Documentation for these changes is available from the link in the     References section.

    All users of Red Hat JBoss Enterprise Application Platform 6.3 on Red Hat     Enterprise Linux 6 are advised to upgrade to these updated packages.
    The JBoss server process must be restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
