CVE-2016-8657
Description
It was discovered that EAP packages in certain versions of Red Hat Enterprise Linux use incorrect permissions for /etc/sysconfig/jbossas configuration files. The file is writable to jboss group (root:jboss, 664). On systems using classic /etc/init.d init scripts (i.e. on Red Hat Enterprise Linux 6 and earlier), the file is sourced by the jboss init script and its content executed with root privileges when jboss service is started, stopped, or restarted.
Statement
It was found that a variant of the Tomcat CVE-2016-6325 exploit is also applicable to Red Hat JBoss Enterprise Application Platform 5 and 6. CVE-2016-8567 addresses these problems with JBoss EAP. The complexity is high as EAP has many files and configuration options. The issue is now corrected in JBoss Enterprise Application Platform EAP 6.4.14.

Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Technical Impact: Read Application Data; Read Files or Directories
An attacker may be able to read sensitive information from the associated resource, such as credentials or configuration information stored in a file.
Access Control
Technical Impact: Gain Privileges or Assume Identity
An attacker may be able to modify critical properties of the associated resource to gain privileges, such as replacing a world-writable executable with a Trojan horse.
Integrity,Other
Technical Impact: Modify Application Data; Other
An attacker may be able to destroy or corrupt critical data in the associated resource, such as deletion of records from a database.
