Title: Siemens Nucleus产品越界写入漏洞

Description:

Nucleus NET模块包含了一系列符合标准的网络和通信协议、驱动程序和实用程序，以在任何嵌入式设备中提供全功能的网络支持。

Siemens Nucleus产品越存在界写入漏洞。该漏洞是由于DNS域名标签解析功能未能正确验证DNS响应中的名称。解析格式错误的响应可能导致写入超过allocatedstructure的结尾。攻击者可利用漏洞在当前进程的上下文中执行代码或造成拒绝服务情况。

Severity: 高

Vulnerability from cvelistv5

Published

Severity ?

8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C

CWE

CWE-787 - Out-of-bounds Write

Summary

A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus Source Code (Versions including affected DNS modules), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). The DNS domain name label parsing functionality does not properly validate the names in DNS-responses. The parsing of malformed responses could result in a write past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to execute code in the context of the current process or cause a denial-of-service condition.
