漏洞描述
中文描述:
Cisco Nexus 9000 Series Fabric Switches是美国思科(Cisco)公司的一款9000系列光纤交换机。 Cisco Nexus 9000 Series Fabric Switches(处于Application Centric Infrastructure (ACI)模式)中的system shell存在后置链接漏洞。该漏洞源于网络系统或产品未正确过滤表示非预期资源的链接或者快捷方式的文件名。攻击者可利用该漏洞访问非法的文件路径。
英文描述:
A vulnerability in the system shell for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to use symbolic links to overwrite system files. These system files may be sensitive and should not be overwritable by non-root users. The attacker would need valid device credentials. The vulnerability is due to incorrect symbolic link verification of directory paths when they are used in the system shell. An attacker could exploit this vulnerability by authenticating to the device and providing crafted user input to specific symbolic link CLI commands. Successful exploitation could allow the attacker to overwrite system files that should be restricted. This vulnerability has been fixed in software version 14.1(1i).
