CVE-2022-36363
CVE-2022-36363
In short
LOGO! controllers fail to validate offset values in TCP packets, allowing attackers to read sensitive data from device memory. This can expose confidential information stored on the controller.
Technical detail
The vulnerability exists in TCP packet handling where offset values are not properly validated before being used to access memory. An attacker on the network can craft malicious TCP packets with arbitrary offset values to read unintended memory regions, potentially exposing sensitive data or configuration details. No authentication is required to exploit this information disclosure vulnerability.
