CVE-2014-0114
Description
From CVE.org
Apache Commons BeanUtils, as distributed in lib/commons-beanutils-1.8.0.jar in Apache Struts 1.x through 1.3.10 and in other products requiring commons-beanutils through 1.9.2, does not suppress the class property, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via the class parameter, as demonstrated by the passing of this parameter to the getClass method of the ActionForm object in Struts 1.
Statement
This flaw allows attackers to manipulate ClassLoader properties on a vulnerable server. The impact of this depends on which ClassLoader properties are exposed. Exploits that lead to remote code execution have been published. These exploits rely on ClassLoader properties that are exposed on Tomcat 8, which is not included in any supported Red Hat products. However, some Red Hat products that ship Struts 1 do expose ClassLoader properties that could potentially be exploited. Additional information can be found in the Red Hat Knowledgebase article: https://access.redhat.com/site/solutions/869353
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)
Integrity,Confidentiality,Availability,Other
Technical Impact: Execute Unauthorized Code or Commands; Alter Execution Logic
The attacker might be able to execute code that is not directly accessible to the attacker. Alternately, the attacker could call unexpected code in the wrong place or the wrong time, possibly modifying critical system state.
Availability,Other
Technical Impact: DoS: Crash, Exit, or Restart; Other
The attacker might be able to use reflection to call the wrong code, possibly with unexpected arguments that violate the API (CWE-227). This could cause the product to exit or hang.
Confidentiality
Technical Impact: Read Application Data
By causing the wrong code to be invoked, the attacker might be able to trigger a runtime error that leaks sensitive information in the error message, such as CWE-536.
