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 affected device.
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.
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.
A low-privileged remote attacker may be able to replace the boot application of the CODESYS Control runtime system, enabling unauthorized code execution.
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.
An unauthenticated remote attacker, who beats a race condition, can exploit a flaw in the communication servers of the CODESYS Control runtime system on Linux and QNX to trigger an out-of-bounds read via crafted socket communication, potentially causing a denial of service.
Insufficient path validation in CODESYS Control allows low privileged attackers with physical access to gain full filesystem access.
An unauthenticated remote attacker can gain access to sensitive information including authentication information when using CODESYS OPC UA Server with the non-default Basic128Rsa15 security policy.
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.
