VAR-201109-0179
Vulnerability from variot - Updated: 2025-04-11 23:05Beckhoff TwinCAT 2.11.0.2004 and earlier allows remote attackers to cause a denial of service via a crafted request to UDP port 48899, which triggers an out-of-bounds read. Beckhoff TwinCAT is a PC-based software solution that provides complete CNC functionality. TwinCAT is prone to a denial-of-service vulnerability. Attackers can exploit this issue to crash the application, denying service to legitimate users. TwinCAT 2.11 R2 Build 2032 is vulnerable. Other versions may also be affected
