High 7.5
Uncontrolled Memory Allocation in CODESYS Gateway Client
The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory cons…

High 8.1
Improper Synchronization in Monitoring in CODESYS Control Runtime
Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacke…

High 7.5
CODESYS Control DoS via Unauthenticated NULL Pointer Dereference
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.

High 8.3
CODESYS Control PKI Exposure Enables Remote Certificate Access
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 services remain…
