Authenticated code execution via unbounded filename copy
Published Jan 26, 2023 · Updated Mar 5, 2025
Stack-based buffer overflow in Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 allows remote authenticated users to execute code via HTTP. The downfile.cgi handler passes the untrusted _filename parameter to sprintf, which copies it into a fixed stack buffer without a size bound. Administrative privileges are required; successful exploitation executes code and can fully compromise the router.
