Title

Cisco Network Academy Packet Tracer software不可信搜索路径漏洞

Description

Cisco Network Academy Packet Tracer software是美国思科（Cisco）公司的一套可视化网络模拟软件。该软件能够模拟文件命令、网络设备的可视化和配置，并模拟数据传输交互等。 Cisco Network Academy Packet Tracer software中存在不可信搜索路径漏洞，该漏洞源于在加载DLL文件之前程序未能充分的对路径和文件名执行输入检测。本地攻击者可通过创建恶意的DLL文件并将其安装到系统目录中利用该漏洞以SYSTEM账户权限在底层Microsoft Windows主机上执行命令。

CVE-2017-12313 (GCVE-0-2017-12313)

Vulnerability from cvelistv5 – Published: 2017-11-16 07:00 – Updated: 2024-08-05 18:36

Summary

An untrusted search path (aka DLL Preload) vulnerability in the Cisco Network Academy Packet Tracer software could allow an authenticated, local attacker to execute arbitrary code via DLL hijacking if a local user with administrative privileges executes the installer in the current working directory where a crafted DLL has been placed by an attacker. The vulnerability is due to incomplete input validation of path and file names of a DLL file before it is loaded. An attacker could exploit this vulnerability by creating a malicious DLL file and installing it in a specific system directory. A successful exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to the SYSTEM account. An attacker would need valid user credentials to exploit this vulnerability.
