Loading vulnerability…
MikroTik RouterOS versions prior to 6.42.7 and 6.40.9 contain an authenticated stack-based buffer overflow in the license upgrade interface, specifically in the licupgr binary. The issue is described as an unsafe sprintf usage where an authenticated user can control input (notably username and password parameters) such that the resulting formatted string overflows a stack buffer. Proof-of-concept details reference a crafted HTTP(S) request (e.g., a GET to /ssl_conn.php with user-controlled usrname and passwd parameters) that triggers the overflow, which can be leveraged to execute arbitrary code and obtain root/system-level access.
