Netwin » Surgeftp : Security Vulnerabilities, CVEs, Published In 2001

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.

NetWin Authentication module (NWAuth) 2.0 and 3.0b, as implemented in SurgeFTP, DMail, and possibly other packages, uses weak password hashing, which could allow local users to decrypt passwords or use a different password that has the same hash value as the correct password.

Directory traversal vulnerability in NetWin SurgeFTP 2.0a and 1.0b allows a remote attacker to list arbitrary files and directories via the 'nlist ...' command.

NetWin SurgeFTP prior to 1.1h allows a remote attacker to cause a denial of service (crash) via an 'ls ..' command.

NetWin SurgeFTP 2.0a and 1.0b allows a remote attacker to cause a denial of service (crash) via a CD command to a directory with an MS-DOS device name such as con.
