Vulnerability Title
Nexus Repository 3 - Server-Side Request Forgery (SSRF) via HTTP Redirect
Source: CVE Program / CVE List V5
Vulnerability Description
Nexus Repository 3 did not apply its existing Server-Side Request Forgery (SSRF) protections to HTTP redirect targets returned by proxy repository upstream servers. Any user with read access to a proxy repository backed by an attacker-controlled or compromised upstream server — including an anonymous user, if anonymous access is enabled — could receive a response from an internal network address or cloud metadata endpoint as repository content, potentially exposing sensitive information such as cloud IAM credentials.

Sonatype Nexus Repository Manager 服务端请求伪造漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Sonatype nexus repository manager是美国Sonatype公司开源的一个软件仓库管理平台。 Sonatype Nexus Repository Manager存在服务端请求伪造漏洞，该漏洞源于未对代理仓库上游服务器返回的HTTP重定向目标应用现有的服务器端请求伪造（SSRF）保护，可能导致具有代理仓库读取权限的用户（包括匿名用户）接收来自内部网络地址或云元数据端点的响应作为仓库内容，从而暴露敏感信息如云IAM凭据。以下版本受到影响：3.0.0版本至3.94.0之前版本。
