The isCallerInRole function in SimpleSecurityManager in JBoss Application Server (AS) 7, as used in Red Hat JBoss Enterprise Application Platform (JBEAP) 6.3.0, does not properly check caller roles, which allows remote authenticated users to bypass access restrictions via unspecified vectors.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1020 advisory.

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

    A race condition flaw, leading to heap-based buffer overflows, was found in     the mod_status httpd module. A remote attacker able to access a status page     served by mod_status on a server using a threaded Multi-Processing Module     (MPM) could send a specially crafted request that would cause the httpd     child process to crash or, possibly, allow the attacker to execute     arbitrary code with the privileges of the apache user. (CVE-2014-0226)

    A denial of service flaw was found in the way httpd's mod_deflate module     handled request body decompression (configured via the DEFLATE input     filter). A remote attacker able to send a request whose body would be     decompressed could use this flaw to consume an excessive amount of system     memory and CPU on the target system. (CVE-2014-0118)

    A denial of service flaw was found in the way httpd's mod_cgid module     executed CGI scripts that did not read data from the standard input.
    A remote attacker could submit a specially crafted request that would cause     the httpd child process to hang indefinitely. (CVE-2014-0231)

    A flaw was found in the WebSocket08FrameDecoder implementation that could     allow a remote attacker to trigger an Out Of Memory Exception by issuing a     series of TextWebSocketFrame and ContinuationWebSocketFrames. Depending on     the server configuration, this could lead to a denial of service.
    (CVE-2014-0193)

    It was found that the isCallerInRole() method of the SimpleSecurityManager     did not correctly check caller roles. A remote, authenticated attacker     could use this flaw to circumvent the caller check in applications that use     black list access control based on caller roles. (CVE-2014-3472)

    Red Hat would like to thank James Roper of Typesafe for reporting     CVE-2014-0193, and CA Technologies for reporting CVE-2014-3472.

    This release of JBoss Enterprise Application Platform also includes bug     fixes and enhancements. Documentation for these changes will be available     shortly from the JBoss Enterprise Application Platform 6.3.0 Release Notes,     linked to in the References.

    All users who require JBoss Enterprise Application Platform 6.3.0 on Red     Hat Enterprise Linux 6 should install these new 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.

Updated Red Hat JBoss Enterprise Application Platform 6.3.0 packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the 'apache' user.
