Netwin » Surgeftp » 2.0a : Security Vulnerabilities, CVEs, CVSS score >= 8

The mirror mechanism in SurgeFTP 2.3a1 allows user-assisted, remote FTP servers to cause a denial of service (restart) via a malformed response to a PASV command.

NetWin SurgeFTP 2.0f and earlier encrypts passwords using weak hashing, a fixed salt value and modulo 40 calculations, which allows remote attackers to conduct brute force password guessing attacks against the administrator account on port 7021.

Buffer overflows in NetWin Authentication Module (NWAuth) 3.0b and earlier, as implemented in DMail, SurgeFTP, and possibly other packages, could allow attackers to execute arbitrary code via long arguments to (1) the -del command or (2) the -lookup command.
