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.
