id: CVE-2012-0392

info:
  name: Apache Struts2 S2-008 RCE
  author: pikpikcu
  severity: medium
  description: The CookieInterceptor component in Apache Struts before 2.3.1.1 does not use the parameter-name whitelist, which allows remote attackers to execute arbitrary commands via a crafted HTTP Cookie header that triggers Java code execution through a static method.
  remediation: Developers should immediately upgrade to at least Struts 2.3.18.
