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.
