Apache Struts <2.3.1.1 - Remote Code Execution

ID: CVE-2012-0394

Severity: medium

Author: tess

Tags: cve,cve2012,ognl,injection,edb,apache,struts

Description

Section titled “Description”

Apache Struts before 2.3.1.1 is susceptible to remote code execution. When developer mode is used in the DebuggingInterceptor component, a remote attacker can execute arbitrary OGNL commands via unspecified vectors, which can allow for execution of malware, obtaining sensitive information, modifying data, and/or gaining full control over a compromised system without entering necessary credentials.. NOTE: the vendor characterizes this behavior as not “a security vulnerability itself.”
