Local code execution via account-name overflow
Published Mar 22, 2026 · Updated Mar 22, 2026
Out-of-bounds write in FTPShell Server 6.83 allows local users to execute arbitrary code through the Account name to ban field. The Manage FTP Accounts dialog accepts a crafted 416-byte prefix, overwrites the saved return address, and transfers control to shellcode embedded in the account-name input. Exploitation requires local interactive access to the Windows management interface, and the resulting code runs in the application user's security context.
