Published Nov 15, 2022 · Updated May 14, 2025 · Revision 3

Vendor: Phoenix Contact Product: Config+ Product: PC Worx Product: PC Worx Express

Summary

Manipulated PC Worx or Config+ files could lead to a heap buffer overflow, release of unallocated memory or a read access violation due to insufficient validation of input data.The attacker needs to get access to an original bus configuration file (*.bcp) to be able to manipulate data inside. After manipulation the attacker needs to exchange the original file by the manipulated one on the application programming workstation.

Update A, 2022-11-14

removed the sentence "Automated systems in operation which were programmed with one of the above-mentioned products are not affected." from Impact.

Details

Impact
Availability, integrity, or confidentiality of an application programming workstation might be compromised by attacks using these vulnerabilities.

Mitigation
We strongly recommend customers to exchange project files only using secure file exchange services. Project files should not be exchanged via unencrypted email.

Remediation
With the next version of Automationworx Software Suite an already implemented remediation measure needs to be corrected to prevent the release of unallocated memory.To prevent the read access violation the validation of the input data will be improved.
We strongly recommend customers to upgrade to Automation Worx Software Suite > 1.89.
