Vulnerabilities

Amazon AWS Client VPN has a buffer overflow that could potentially allow a local actor to execute arbitrary commands with elevated permissions. This is resolved in 3.11.1 on Windows, 3.9.1 on macOS, and 3.12.1 on Linux. NOTE: although the macOS resolution is the same as for CVE-2024-30165, this vulnerability on macOS is not the same as CVE-2024-30165.

An unauthenticated remote attacker can causes the CODESYS web server to access invalid memory which results in a DoS.

Out-of-Bounds read vulnerability in OSCAT Basic Library allows an local, unprivileged attacker to access limited internal data of the PLC which may lead to a crash of the affected service.

A local attacker with low privileges can read and modify any users files and cause a DoS in the working directory of the affected products due to exposure of resource to wrong sphere. 

An unauthenticated remote attacker can use a malicious OPC UA client to send a crafted request to affected CODESYS products which can cause a DoS due to incorrect calculation of buffer size.
