In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.

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.

There is a cross-site scripting (XSS) vulnerability in an NI Web Server component installed with several NI products. Depending on the product(s) in use, remediation guidance includes: install SystemLink version 2021 R3 or later, install FlexLogger 2022 Q2 or later, install LabVIEW 2021 SP1, install G Web Development 2022 R1 or later, or install Static Test Software Suite version 1.2 or later.

The SysDrv3S driver in the CODESYS Control runtime system on Microsoft Windows allows any system user to read and write within restricted memory space.

A remote, unauthenticated attacker can send a specific crafted HTTP or HTTPS requests causing a buffer over-read resulting in a crash of the webserver of the CODESYS Control runtime system.

An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. This results in the communication channel to be closed.

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.

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

A unsafe deserialization vulnerability exists in the ComponentModel Profile.FromFile() functionality of CODESYS GmbH CODESYS Development System 3.5.16 and 3.5.17. A specially crafted file can lead to arbitrary command execution. An attacker can provide a malicious file to trigger this vulnerability.
