CVE-2021-25178: Siemens JT2Go DXF and DWG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
First published: Mon Jan 18 2021(Updated: )
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. 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 DXF and DWG files. 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 code in the context of the current process.
