An adversary could cause a continuous restart loop to the entire device by sending a large quantity of HTTP GET requests if the controller has the built-in web server enabled but does not have the built-in web server completely set up and configured for the SNAP PAC S1 Firmware version R10.3bShow less

An adversary could crash the entire device by sending a large quantity of ICMP requests if the controller has the built-in web server enabled but does not have the built-in web server completely set up and configured for the SNAP PAC S1 Firmware version R10.3bShow less

There are no requirements for setting a complex password in the built-in web server of the SNAP PAC S1 Firmware version R10.3b, which could allow for a successful brute force attack if users don't set up complex credentials.Show less

Opto 22 SoftPAC Project Version 9.6 and prior. Paths specified within the zip files used to update the SoftPAC firmware are not sanitized. As a result, an attacker with user privileges can gain arbitrary file write access with system access.Show less

Opto 22 SoftPAC Project Version 9.6 and prior. SoftPAC communication does not include any credentials. This allows an attacker with network access to directly communicate with SoftPAC, including, for example, stopping the service remotely.Show less

Opto 22 SoftPAC Project Version 9.6 and prior. SoftPACAgent communicates with SoftPACMonitor over network Port 22000. However, this port is open without any restrictions. This allows an attacker with network access to control the SoftPACAgent service including updating SoftPAC firmware, starting or stopping service, or writing to certain registry values.Show less

A vulnerable file in Opto 22 PAC Project Professional versions prior to R9.4006, PAC Project Basic versions prior to R9.4006, PAC Display Basic versions prior to R9.4f, PAC Display Professional versions prior to R9.4f, OptoOPCServer versions prior to R9.4c, and OptoDataLink version R9.4d and prior versions that were installed by PAC Project installer, versions prior to R9.4006, is susceptible to a heap-based buffer overflow condition that may allow remote code execution on the target system. Opto 22 suggests upgrading to the new product version as soon as possible.Show less

A specially crafted configuration file could be used to cause a stack-based buffer overflow condition in the OPCTest.exe, which may allow remote code execution on Opto 22 PAC Project Professional versions prior to R9.4008, PAC Project Basic versions prior to R9.4008, PAC Display Basic versions prior to R9.4g, PAC Display Professional versions prior to R9.4g, OptoOPCServer version R9.4c and prior that were installed by PAC Project installer, versions prior to R9.4008, and OptoDataLink version R9.4d and prior that were installed by PAC Project installer, versions prior to R9.4008.
