An issue was discovered in PHOENIX CONTACT PC Worx through 1.86, PC Worx Express through 1.86, and Config+ through 1.86. A manipulated PC Worx or Config+ project file could lead to an Uninitialized Pointer and remote code execution. The attacker needs to get access to an original PC Worx or Config+ project file to be able to manipulate it. After manipulation, the attacker needs to exchange the original file with the manipulated one on the application programming workstation.

The Web-based Management allows a remote low privileged Engineer user to install additional APPs on the device downloaded from the PLCnext Store without implementing any data verification mechanism, leading to the capability for an Engineer user to reach arbitrary code execution with root privileges on the PLC device. A successful exploitation may allow to install a manipulated APP package, potentially impacting integrity and availability of the PLCnext Control.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Phoenix Contact Automationworx. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of MWT files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Phoenix Contact Classic Automation Worx Software Suite in Version 1.87 and below is affected by a remote code execution vulnerability. Manipulated PC Worx or Config+ projects could lead to a remote code execution when unallocated memory is freed because of incompletely initialized 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. Availability, integrity, or confidentiality of an application programming workstation might be compromised by attacks using these vulnerabilities. Automated systems in operation which were programmed with one of the above-mentioned products are not affected.

Remedy

Temporary Fix / 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 the affected data will be initialized completely and thereby freeing of unallocated memory will be prevented.
