Title: Netwin SurgeFTP Malformed Request Denial of Service Vulnerability
Severity: MODERATE
Description:
SurgeFTP is a FTP Server distributed and maintained by Netwin. SurgeFTP is a configurable, easily maintained ftp server, functional on both the UNIX and Windows platforms. This vulnerability affects vulnerable SurgeFTP servers that allow users, both authenticated as well as anonymous.
A problem with the SurgeFTP program could allow a denial of service to legitimate users. This problem is due to the improper handling of specific requests presented by the client to the server.
It is possible to cause the server to cease functioning by logging in, and requesting a list of first the root directory, then a list of the directory above the root directory. Upon receiving the request, the ftp server resets connections. After the connections are reset, the server exits and ceases to function.
Affected Products:
- NetWin SurgeFTP 1.0.0b
