mwe file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier is vulnerable to out-of-bounds read remote code execution. Manipulated PC Worx projects could lead to a remote code execution due to insufficient input data validation.
mwe file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier is vulnerable to out-of-bounds read remote code execution. Manipulated PC Worx projects could lead to a remote code execution due to insufficient input data validation.
With the next version of Automation Worx Software Suite (Version > 1.87) a sharpened input data validation with respect to buffer size and description of size and number of objects referenced in a file will be implemented.
Configurations
Workarounds
We strongly recommend customers to exchange project files only using secure file exchange services. Project files should not be exchanged via unencrypted email.
In addition, we recommend exchanging or storing project files together with a checksum to ensure their integrity.
