Vulnerability from emb3d
Type
Description
Many devices that allow the execution of custom application programs, such as IEC 61131 based programs, also support “program uploads” to extract the running code from the device for various diagnostic functions. To support the program upload function, the device must provide the IDE with machine readable and human-presentable source code, rather than the executable compiled code. Therefore, the device must store two copies of the code, the source code (used to inform program upload function) and the executed compiled code. If a threat actor can modify the source code in memory, it will prevent the program upload function from accurately uploading/reporting the actual code executing on the device and allow any later downloaded malicious code to stay undetected.

- CWE-829 - Inclusion of Functionality from Untrusted Control Sphere
Summary
An attacker with the ability to modify a user program may change user program code on some ControlLogix, CompactLogix, and GuardLogix Control systems. Studio 5000 Logix Designer writes user-readable program code to a separate location than the executed compiled code, allowing an attacker to change one and not the other.
