CVE-2021-31343

Quick assessment

Affected
n/a Siemens Solid Edge
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 Solid Edge是德国Siemens公司的一款三维CAD软件。该软件可用于零件设计、装配设计、钣金设计、焊接设计等行业。 Solid Edge SE2020(所有版本< 2020MP14) 和 Solid Edge SE2021(所有版本< SE2021MP5)存在缓冲区错误漏洞，该漏洞源于jutil.dll库在解析DFT文件时缺乏对用户提供的数据的正确验证。这可能导致超出已分配结构末端的越界写入。攻击者可利用该漏洞在当前进程的上下文中执行代码。

Source: CVE Program / CVE List V5
Vulnerability Description
The jutil.dll library in all versions of Solid Edge SE2020 before 2020MP14 and all versions of Solid Edge SE2021 before SE2021MP5 lack proper validation of user-supplied data when parsing DFT files. This could result in an out-of-bounds write past the end of an allocation structure. An attacker could leverage this vulnerability to execute code in the context of the current process.
