| 17 | + 'Description' => %q{ |
| 18 | + This exploit abuses a vulnerability in the HP Data Protector. The vulnerability exists |
| 19 | + in the Backup client service, which listens by default on TCP/5555. The EXEC_INTEGUTIL |
| 20 | + request allows to execute arbitrary commands from a restricted directory. Since it |
| 21 | + includes a perl executable, it's possible to use an EXEC_INTEGUTIL packet to execute |
| 22 | + arbitrary code. On linux targets, the perl binary isn't on the restricted directory, but |
| 23 | + an EXEC_BAR packet can be used to access the perl binary, even in the last version of HP |
| 24 | + Data Protector for linux. This module has been tested successfully on HP Data Protector |
| 25 | + 9 over Windows 2008 R2 64 bits and CentOS 6 64 bits. |
