NetWin SurgeFTP

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.

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.

Buffer overflow in NetWin SurgeFTP before 23d2 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string within the authentication request.

The administration web interface in NetWin SurgeFTP 2.3a2 and earlier allows remote attackers to cause a denial of service (daemon crash) via a large integer in the Content-Length HTTP header, which triggers a NULL pointer dereference when memory allocation fails.

cgi/surgeftpmgr.cgi (aka the Web Manager interface on TCP port 7021 or 9021) in NetWin SurgeFTP version 23f2 has XSS via the classid, domainid, or username parameter.

Cross-site scripting (XSS) vulnerability in the mirrored server management interface in SurgeFTP 2.3a1 allows user-assisted, remote FTP servers to inject arbitrary web script or HTML via a malformed response without a status code, which is reflected to the user in the resulting error message. NOTE: this can be leveraged for root access via a sequence of steps involving web script that creates a new FTP user account.

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.

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.

The administrative interface (surgeftpmgr.cgi) for SurgeFTP Server 1.0b through 2.2k1 allows remote attackers to cause a temporary denial of service (crash) via requests with two percent (%) signs in the CMD parameter.

SurgeFTP 2.2m1 allows remote attackers to cause a denial of service (application hang) via the LEAK 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.

Multiple cross-site scripting (XSS) vulnerabilities in surgeftpmgr.cgi in NetWin SurgeFTP 2.3a6 allow remote attackers to inject arbitrary web script or HTML via the (1) domainid or (2) classid parameter in a class action.
