Miggo AIRoot Cause Analysis

The vulnerability centers around improper authorization in YARN container execution. Analysis of Hadoop's architecture reveals that:

  1. LinuxContainerExecutor.startContainer() is the primary method for launching containers with user privileges
  2. The vulnerability description explicitly mentions privilege escalation from yarn to root
  3. Historical Hadoop vulnerabilities (CVE-2016-3086) show similar patterns in container execution paths
  4. The CWE-285 classification indicates missing authorization checks in security-sensitive operations While exact patch details are unavailable, these functions are central to container privilege management and match the vulnerability's behavioral profile.
