漏洞描述
中文描述:
Cisco Wireless LAN Controller(WLC)是美国思科(Cisco)公司的一款无线局域网控制器产品。该产品在无线局域网中提供安全策略、入侵检测等功能。 Cisco Wireless LAN Controller 管理接口存在安全漏洞,该漏洞源于密码执行不当。攻击者可以通过使用精心制作的凭据登录受影响的设备来利用此漏洞。 成功的利用可能允许攻击者绕过身份验证并以管理员身份登录设备。 攻击者可以获得与管理用户相同级别的权限,但这取决于精心制作的凭据。以下产品和版本受到影响:3504 无线控制器、5520 无线控制器、8540 无线控制器、Mobility Express和虚拟无线控制器 (vWLC)。
英文描述:
A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to bypass authentication controls and log in to the device through the management interface This vulnerability is due to the improper implementation of the password validation algorithm. An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials. A successful exploit could allow the attacker to bypass authentication and log in to the device as an administrator. The attacker could obtain privileges that are the same level as an administrative user but it depends on the crafted credentials. Note: This vulnerability exists because of a non-default device configuration that must be present for it to be exploitable. For details about the vulnerable configuration, see the Vulnerable Products section of this advisory.
