TITLE

Delta Industrial Automation WPLSoft DVP File Parsing Heap-Based Buffer Overflow Remote Code Execution Vulnerability

Trust: 2.1

sources: ZDI: ZDI-16-648 // ZDI: ZDI-16-656 // ZDI: ZDI-16-657

DESCRIPTION

An issue was discovered in Delta Electronics WPLSoft, Versions prior to V2.42.11, ISPSoft, Versions prior to 3.02.11, and PMSoft, Versions prior to2.10.10. There are multiple instances of heap-based buffer overflows that may allow malicious files to cause the execution of arbitrary code or a denial of service. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Delta Industrial Automation ISPSoft. 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 processing of dvp files. The process does not properly validate the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of current process. Delta Electronics WPLSoft and others are software control platforms used by Delta Electronics to edit the Delta DVP series of programmable logic controllers (PLCs). A heap buffer overflow vulnerability exists in several Delta Electronics products
