Quick assessment

Affected
Cisco Cisco Identity Services Engine Software
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以下是该漏洞描述信息的中文翻译： Cisco ISE 中的 SXP REST API 存在一个漏洞，可能允许经过身份验证的远程攻击者发起 SQL 注入攻击。 该漏洞是由于对 REST API 调用中用户提供的输入缺乏充分验证所致。攻击者可以通过向受影响设备发送精心构造的输入来利用此漏洞。成功利用该漏洞可能使攻击者能够查看或修改受影响设备底层数据库中的数据。在单节点部署中，成功利用此漏洞可能导致受影响的 ISE 节点变得不可用，从而导致拒绝服务（DoS）状态。在这种状态下，尚未完成身份验证的终端设备将无法访问网络，直

Vulnerability Title
Cisco Identity Search Engine SXP REST API SQL Injection Vulnerability
Source: CVE Program / CVE List V5
Vulnerability Description
A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This vulnerability is due to insufficient validation of user-supplied input in REST API calls. An attacker could exploit this vulnerability by sending crafted input to an affected device. A successful exploit could allow the attacker to view or modify data on the underlying database for the affected device. In single-node deployments, successful exploitation of this vulnerability could cause the affected ISE node to become unavailable, resulting in a DoS condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored. To exploit this vulnerability, the attacker must have valid administrative credentials, have the SXP service enabled, and have at least one SXP connection configured.
