(0Day) Delta Industrial Automation PMSoft Project File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

Ghirmay Desta

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Delta Industrial Automation PMSoft. 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 parsing of information for a TTreeView object in a ppm project file. The issue results from the lack of proper validation of 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 arbitrary code under the context of the current process.
