The following paper is available in full from my website, i have chosen not to post the entire thing here as it is quite long. http://www.suid.edu/advisories/001.txt [EMAIL PROTECTED] - the dangers of ftp conversions on misconfigured systems/ftpd (specifically wu-ftpd) Summary: There exists a vulnerability with certain configurations of certain ftp daemons with which users with a valid ftp only acccount on a system may execute arbitrary commands (including binaries supplied by themselves). There also exists the possibilty that anonymous ftp users may execute arbitrary commands (also including binaries supplied by themselves). While this vulnerability is entirely configuration dependent. The required configuration is rather common. The requirements can be found in the example exploit section. Usually such misconfigurations are made only by the security-handicapped, and the documentation-illiterate. There is volumous amounts of documentation around which warn against this kind of configuration however it does not touch on this exact problem. Nor does that seem to prevent people from doing this time after time. Regards, [EMAIL PROTECTED]
