High 7.5
Out-of-bounds Write in CODESYS Control
The affected products perform improper length checking when parsing incoming HTTP requests, resulting in a size-limited out-of-bounds write. An unauthenticated remote attacker can exploit this flaw to cause a denial of service via a system crash on the affect…

High 8.1
Incorrect Authorization in CODESYS Control
The affected products insufficiently verify authorization when deleting user accounts. An authenticated, low-privileged remote user can exploit this vulnerability to delete other users, including those with higher privileges.
-
High 7.5
CODESYS Control Audit Log Format String DoS
An unauthenticated remote attacker may be able to control the format string of messages processed by the Audit Log of the CODESYS Control runtime system, potentially resulting in a denial‑of‑service (DoS) condition.
-
High 8.8
CODESYS Control Boot Application Replacement Enables Code Execution
A low-privileged remote attacker may be able to replace the boot application of the CODESYS Control runtime system, enabling unauthorized code execution.
-
High 7.5
CODESYS Control - Invalid type usage in visualization
An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
