Wyse Thin Client hagent.exe Unspecified Buffer Overflow

critical Nessus Plugin ID 40862

Language:

Synopsis

Arbitrary code can be executed on the remote host.

Description

The version of the Wyse Thin Client HAgent service installed on the remote host is at risk of a remote buffer overflow attack.

An unauthenticated attacker can exploit this flaw by sending a specially crafted packet to the remote host. Successful exploitation would result in remote code execution with the privileges of the service itself.

Solution

Upgrade to the latest version of Wyse Device Manager (4.7.2) and apply the two security updates (HF 04072019009 and HF04072019709).
