Vulnerability from variot

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. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected 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 parsing of MWE files by the PC WORX and PC WORX Express executables. 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 PC Worx and Phoenix Contact PC Worx Express are both a set of programming software for PLC (programmable logic controller) of Phoenix Contact (Germany Phoenix Contact)
