Refer to the JBoss Enterprise Application Platform 7.1 Release Notes, linked to in the References section, for information on the most significant bug fixes and enhancements included in this release.

Security Fix(es):

  • A Denial of Service can be caused when a long request is sent to EAP 7. (CVE-2016-7046)

  • The jboss init script unsafe file handling resulting in local privilege escalation. (CVE-2016-8656)

  • A deserialization vulnerability via readValue method of ObjectMapper which allows arbitrary code execution. (CVE-2017-7525)

  • JMSObjectMessage deserializes potentially malicious objects allowing Remote Code Execution. (CVE-2016-4978)

  • Undertow is vulnerable to the injection of arbitrary HTTP headers, and also response splitting. (CVE-2016-4993)

  • The domain controller will not propagate its administrative RBAC configuration to some slaves leading to escalate their privileges. (CVE-2016-5406)

  • Internal IP address disclosed on redirect when request header Host field is not set. (CVE-2016-6311)

  • Potential EAP resource starvation DOS attack via GET requests for server log files. (CVE-2016-8627)

  • Potential http request smuggling as Undertow parses the http headers with unusual whitespaces. (CVE-2017-7559)

  • Properties based files of the management and the application realm are world readable allowing access to users and roles information to all the users logged in to the system. (CVE-2017-12167)

  • RBAC configuration allows users with a Monitor role to view the sensitive information. (CVE-2016-7061)
