VAR-201307-0317
Vulnerability from variot - Updated: 2023-12-18 14:06Triangle Research International (aka Tri) Nano-10 PLC devices with firmware before r81 use an incorrect algorithm for bounds checking of data in Modbus/TCP packets, which allows remote attackers to cause a denial of service (networking outage) via a crafted packet to TCP port 502. The Triangle Research Nano-10 PLC is a controller for automated manufacturing. Attack, you need to manually restart to get normal functionality. Nano-10 PLC is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the affected device to crash, denying service to legitimate users. Nano-10 PLC running firmware versions prior to r81 are vulnerable. http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsq24002
