Remote code execution in Planet eStream before 6.72.10.07 allows remote attackers to execute server-side code via unauthenticated file uploads. Upload2.ashx and Ajax.asmx/ProcessUpload2 accept attacker-controlled file content and extensions without effective backend validation, allowing webshell placement. No credentials are required, and successful uploads let attackers run commands as the web server and take over the instance.
