CVE-2023-20030— Cisco Identity Services Engine XML External Entity Injection Vulnerability

Cisco Identity Services Engine XML External Entity Injection Vulnerability

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to access sensitive information, conduct a server-side request forgery (SSRF) attack through an affected device, or negatively impact the responsiveness of the web-based management interface itself. This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of confidential information. A successful exploit could also cause the web application to perform arbitrary HTTP requests on behalf of the attacker or consume memory resources to reduce the availability of the web-based management interface. To successfully exploit this vulnerability, an attacker would need valid Super Admin or Policy Admin credentials.

XML外部实体引用的不恰当限制(XXE)

Cisco Identity Services Engine 代码问题漏洞

Cisco Identity Services Engine（ISE）是美国思科（Cisco）公司的一款环境感知平台（ISE身份服务引擎）。该平台通过收集网络、用户和设备中的实时信息，制定并实施相应策略来监管网络。 Cisco Identity Services Engine (ISE) 3.2 及之前版本存在安全漏洞，该漏洞源于在解析某些 XML 文件时对 XML 外部实体 (XXE) 条目的处理不当，允许经过身份验证的远程攻击者访问敏感信息，通过受影响的设备进行服务器端请求伪造 (SSRF) 攻击。
