Vulnerable Systems:
* Hewlett-Packard Virtual SAN Appliance
Authentication is not required to exploit this vulnerability.
The flaw exists within the hydra.exe component which listens by default on port 13838. When parsing a login request the Hydra daemon will call sscanf() using fixed-length stack buffers and no length checks. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM service.
This vulnerability could be mitigated by administrators by restricting communication with the hydra agent to known client IP addresses.
