Affected
Siemens JT2Go
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Siemens Jt2go是德国Siemens公司的一款JT文件查看器。该软件用于三维图形轻量化预览，可进行3D缩放、全景、旋转、缩放和重定位，具有精确3D测量、基本3D剖面查看、改进的选项过滤器等多种功能。 JT2Go中存在缓冲区错误漏洞，该漏洞源于网络系统或产品在内存上执行操作时，未正确验证数据边界，导致向关联的其他内存位置上执行了错误的读写操作。攻击者可利用该漏洞导致缓冲区溢出或堆溢出等。
