Overview
- Description
- Western Digital My Cloud EX2 Ultra firmware 2.31.183 allows web users (including guest account) to remotely execute arbitrary code via a stack-based buffer overflow. There is no size verification logic in one of functions in libscheddl.so, and download_mgr.cgi makes it possible to enter large-sized f_idx inputs.
