CVE-2013-0655: Schneider Electric Software Update Utility

High severity, CVSS 9.3. EPSS: 2.9% chance of exploitation in the next 30 days.

The client in Schneider Electric Software Update (SESU) Utility 1.0.x and 1.1.x does not ensure that updates have a valid origin, which allows man-in-the-middle attackers to spoof updates, and consequently execute arbitrary code, by modifying the data stream on TCP port 80.
