Synopsis

The remote Windows host contains an application that is affected by a buffer overflow vulnerability.

Description

Wyse Device Manager is installed on the remote system. The installed version is affected by a buffer overflow vulnerability. By sending a specially crafted request to the server, it may be possible for an unauthorized attacker to crash the server or execute arbitrary commands on the remote system with system level privileges.

Solution

Apply vendor-supplied patches.

Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the Wyse Device Manager Buffer Overflow vulnerability:

Metasploit: exploit/multi/wyse/hagent_untrusted_hsdata
[Wyse Rapport Hagent Fake Hserver Command Execution]
Exploit-DB: exploits/hardware/dos/19137.rb
[EDB-19137: Wyse - Machine Remote Power Off (Denial of Service) (Metasploit)]
Exploit-DB: exploits/multiple/remote/9934.rb
