CVE-2015-0279
Description
It was found that the 'do' parameter permitted expression language (EL) injection, which could allow a remote attacker to execute Java methods on an affected server.
Statement
This issue did not affect any version of Red Hat JBoss Enterprise Application Platform 5 as they did not include the vulnerable version of the RichFaces component. JBoss EAP 5.x includes versions 3.3.1.x of RichFaces; this vulnerability was introduced in version 4.x of RichFaces.
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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Files or Directories; Read Application Data
The injected code could access restricted data / files.
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability,Other
Technical Impact: Execute Unauthorized Code or Commands
Code injection attacks can lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing. Additionally, code injection can often result in the execution of arbitrary code or at least modify what code can be executed.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
