Summary
In KUNBUS piControl version 2.6.2, a CWE-787 out-of-bounds write vulnerability exists in the process-image management functionality. It allows a local authenticated attacker with device configuration access to write attacker-controlled data outside the bounds of the process-image buffer and corrupt adjacent kernel memory, by supplying crafted device configuration data and input through the piControl character device, leading to kernel memory corruption and denial of service.
Risk Assessment
An attacker with local access and configuration privileges can corrupt kernel memory, potentially causing system crashes or arbitrary code execution in the kernel. This poses a serious threat to the integrity of industrial systems.
Recommendation
Upgrade KUNBUS piControl to a patched version. Also restrict device configuration access to trusted personnel only.
