Technical details

A stack-based buffer overflow (CWE-121) exists in the /boafrm/formFilter handler of the boa web server when the addFilterUrl or addFilterUrlFlag action is set. The url parameter is copied via unbounded strcpy() into a 36-byte stack buffer with no length validation; payloads exceeding ~35 bytes overflow adjacent stack memory and payloads ≥1000 bytes overwrite callee-saved MIPS registers, causing a denial of service or enabling RCE. Attack requires authentication (POST /boafrm/formLogin session) and network access to the web interface; no user interaction needed.
