| 19 | + This module exploits a remote buffer overflow in HP Intelligent Management Center |
| 20 | + UAM. The vulnerability exists in the uam.exe component, when using sprint in a |
| 21 | + insecure way for logging purposes. The vulnerability can be triggered by sending a |
| 22 | + malformed packet to the 1811/UDP port. The module has been successfully tested on |
| 23 | + HP iMC 5.0 E0101 and UAM 5.0 E0102 over Windows Server 2003 SP2 (DEP bypass). |
