CWE-287Published: July 29, 2011· Updated: Jun 16, 2026
Official Description
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.
Technical Analysis
CVE-2011-2963 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2011-2963. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
