PHOENIX CONTACT: Automationworx BCP File Parsing Vulnerabilities
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.
