An improper validation of integrity check value vulnerability exists in
AVEVA PI Connector for CygNet Versions 1.6.14 and prior that, if exploited, could allow a miscreant with elevated privileges to modify PI Connector for CygNet local data files (cache and buffers) in a way that causes the connector service to become unresponsive.
The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
