TITLE

Siemens JT2Go DXF File Parsing Untrusted Pointer Dereference Remote Code Execution Vulnerability

Trust: 1.4

sources: ZDI: ZDI-21-222 // ZDI: ZDI-21-221

DESCRIPTION

An issue was discovered in Open Design Alliance Drawings SDK before 2021.11. A NULL pointer dereference exists when rendering malformed .DXF and .DWG files. This can allow attackers to cause a crash, potentially enabling a denial of service attack (Crash, Exit, or Restart). Open Design Alliance Drawings SDK Has NULL A pointer dereference vulnerability exists.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. 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 files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process. The development kit accesses the data in .dwg and .dgn through a convenient, object-oriented API, and provides functions such as C++ API, support for repairing files, and support for .NET, JAVA, and Python development languages
