N/A
Vulnerability Description
In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control headers (X-Copy-From, X-Copy-From-Account) from S3 API requests when s3_acl=true. An
attacker can inject these headers into a signed PUT request targeting their own bucket, causing Swift to perform a server-side copy from another tenant's private object. The source object authorization is bypassed because the S3API middleware has already authorized the request against the destination. The attacker can read any object whose project_id, container name, and object name are known, regardless of the source object's ACLs or ownership. This requires the non-default s3_acl=true configuration.

Vulnerability Title
OpenStack Swift 授权问题漏洞
Vulnerability Description
OpenStack Swift是OpenStack基金会开源的一个存储永久静态数据的存储项目。 OpenStack Swift 2.38.0及之前版本存在授权问题漏洞,该漏洞源于S3API中间件未清理S3 API请求中的Swift原生控制头(X-Copy-From、X-Copy-From-Account),可能导致攻击者通过注入这些标头执行服务端复制操作,绕过源对象授权,读取其他租户的私有对象。
