CVE-2022-22515 8.1 - High - April 07, 2022

A remote, authenticated attacker could utilize the control program of the CODESYS Control runtime system to use the vulnerability in order to read and modify the configuration file(s) of the affected products.

Exposure of Resource to Wrong Sphere

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request

CVE-2022-22514 7.1 - High - April 07, 2022

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.
