VAR-202505-0909

Vulnerability from variot - Updated: 2025-05-26 12:47

An Unchecked Input for Loop Condition in RT-Labs P-Net version 1.0.1 or earlier allows an attacker to cause IO devices that use the library to enter an infinite loop by sending a malicious RPC packet. RT-Labs of P-Net contains vulnerabilities regarding unchecked loop condition input values and improper validation of quantities specified in the input.Service operation interruption (DoS) It may be in a state. RT-Labs P-Net is an open source PROFINET protocol stack from RT-Labs that implements standard communication between industrial devices and PROFINET controllers.

RT-Labs P-Net 1.0.1 and earlier versions have a security vulnerability. The vulnerability is caused by not checking the loop condition
