An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition.

A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all servic...

CODESYS Runtime Toolkit-based products may expose sensitive files to local low-privileged operating system users due to default file permissions.

Insufficient path validation in CODESYS Control allows low privileged attackers with physical access to gain full filesystem access.

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

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.

A low-privileged remote attacker could exploit the vulnerability and inject additional system commands via file system libraries which could give the attacker full control of the device.

In CODESYS Control in multiple versions a improper restriction of operations within the bounds of a memory buffer allow an remote attacker with user privileges to gain full access of the device.

In multiple versions of multiple Codesys products, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpAppBP component to read internally from an invalid address, poten...
