VAR-202007-0238

Vulnerability from variot - Updated: 2023-12-18 12:16

PLCopen XML file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier can lead to a stack-based overflow. 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 PLCOpen XML files. When parsing the pou element, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based 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)

    "data": "PLCopen XML file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier can lead to a stack-based overflow. 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 PLCOpen XML files. When parsing the pou element, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based 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)",
