Description:
Eyal Udassin has reported a vulnerability in Proficy HMI/SCADA - CIMPLICITY, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
The vulnerability is caused due to a boundary error in w32rtr.exe when processing packets and can be exploited to cause a heap-based buffer overflow by sending a specially-crafted packet to default port 32000/TCP.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in version 6.1. Other versions may also be affected.
Solution:
Apply hotfixes. Please see the vendor's advisory for details.
