TCPUploadServer.exe in Progea Movicon 11.2 before Build 1084 does not require authentication for critical functions, which allows remote attackers to obtain sensitive information, delete files, execute arbitrary programs, or cause a denial of service (crash) via a crafted packet to TCP port 10651.
CWE-287 - Improper Authentication
Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
