Vulnerability from variot
A vulnerability was found in Rockwell Automation RSLinx Classic versions 4.10.00 and prior. An input validation issue in a .dll file of RSLinx Classic where the data in a Forward Open service request is passed to a fixed size buffer, allowing an attacker to exploit a stack-based buffer overflow condition. Rockwell Automation RSLinx Classic Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The program supports access to RockwellSoftware and Allen-Bradley applications via Allen-Bradley programmable controllers. A stack buffer overflow vulnerability exists in the .dll file in Rockwell Automation RSLinx Classic 4.10.00 and earlier, which can be exploited by remote attackers to execute code on target devices. RSLinx Classic is prone to a local stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Attackers can exploit this issue to execute arbitrary code with elevated privileges. Failed exploit attempts will likely cause denial-of-service conditions
