ConfD CLI Secure Shell Server Privilege Escalation Vulnerability

A vulnerability in ConfD could allow an authenticated, local attacker to execute arbitrary commands at the level of the account under which ConfD is running, which is commonly root. To exploit this vulnerability, an attacker must have a valid account on an affected device. The vulnerability exists because the affected software incorrectly runs the SFTP user service at the privilege level of the account that was running when the ConfD built-in Secure Shell (SSH) server for CLI was enabled. If the ConfD built-in SSH server was not enabled, the device is not affected by this vulnerability. An attacker with low-level privileges could exploit this vulnerability by authenticating to an affected device and issuing a series of commands at the SFTP interface. A successful exploit could allow the attacker to elevate privileges to the level of the account under which ConfD is running, which is commonly root. Note: Any user who can authenticate to the built-in SSH server may exploit this vulnerability. By default, all ConfD users have this access if the server is enabled. Software updates that address this vulnerability have been released.

Cisco ConfD 安全漏洞

Cisco ConfD是美国思科（Cisco）公司的一个管理软件。 Cisco ConfD存在安全漏洞，该漏洞源于受影响的软件以特权用户启用CLI的ConfD内置SSH服务器时运行的情况下错误地运行SFTP用户服务。该漏洞允许经过身份验证的本地攻击者在远行ConfD的账户中执行任意命令，并且可以通过对受影响的设备进行身份验证并在SFTP接口发送一系列命令将账户权限提升到特权用户。
