Description

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

This release of Red Hat JBoss Enterprise Application Platform 7.1.0 serves as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.0, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.

Security Fix(es):

  • A Denial of Service can be caused when a long request is sent to EAP 7. (CVE-2016-7046)
  • World executable permission on bin/jboss-cli after installation. Any users of the system could cause harm, or shutdown the running instance. (CVE-2016-7066)
  • 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)
  • Inefficient Header Cache could cause denial of service. (CVE-2016-9589)
  • The log file viewer allows arbitrary file read to authenticated user via path traversal. (CVE-2017-2595)
  • HTTP Request smuggling vulnerability due to permitting invalid characters in HTTP requests. (CVE-2017-2666)
  • Websocket non clean close can cause IO thread to get stuck in a loop. (CVE-2017-2670)
  • Privilege escalation with security manager's reflective permissions when granted to Hibernate Validator. (CVE-2017-7536)
  • 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)
  • Improper whitespace parsing leading to potential HTTP request smuggling. (CVE-2017-12165)
