Executive brief
War FTP is a software application used to host file transfer services, allowing users to upload and download files over a network. A critical security flaw in this software allows a remote attacker to take control of the server by sending specially crafted data. This could result in the theft of sensitive files, unauthorized modification of data, or a complete shutdown of the file transfer service.
Technical details
A classic buffer overflow vulnerability exists in the War FTP daemon. The flaw is triggered when the application fails to properly validate the length of input data before copying it into a fixed-size memory buffer. A remote, unauthenticated attacker can exploit this by sending a malicious request to the FTP service, leading to memory corruption. Successful exploitation allows the attacker to overwrite the instruction pointer and execute arbitrary code with the privileges of the FTP service. This vulnerability is reachable over the network without prior authentication.
