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.

CVE-2007-3768
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.
CVE-2007-3769
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.
