TITLE

Siemens Solid Edge Viewer JT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability

Trust: 1.4

sources: ZDI: ZDI-23-088 // ZDI: ZDI-23-087

DESCRIPTION

A vulnerability has been identified in JT Open (All versions < V11.1.1.0), JT Utilities (All versions < V13.1.1.0), Solid Edge (All versions < V2023). The Jt1001.dll contains an out of bounds write past the end of an allocated structure while parsing specially crafted JT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15058, ZDI-CAN-19076, ZDI-CAN-19077). JT2Go and Teamcenter Visualization Exists in an out-of-bounds write vulnerability. Zero Day Initiative To this vulnerability ZDI-CAN-15058 Was numbering.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in 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 JT files
