VAR-202008-1033

Vulnerability from variot - Updated: 2022-05-04 09:02

Out-of-bounds Write vulnerability exists in Modicon M218 Logic Controller (V5.0.0.7 and prior) which could cause Denial of Service when sending specific crafted IPV4 packet to the controller: Sending a specific IPv4 protocol package to Schneider Electric Modicon M218 Logic Controller can cause IPv4 devices to go down. The device does not work properly and must be powered back on to return to normal. Modicon M218 Logic Controller Is vulnerable to out-of-bounds writes.Service operation interruption (DoS) It may be put into a state
