Vulnerability Title
RustFS Snowball Auto-Extract: Path Traversal allows cross-bucket object injection
Vulnerability Description
RustFS is a distributed object storage system built in Rust. In 1.0.0-beta.4, authenticated users with only PutObject permission on their own bucket can exploit a path traversal vulnerability in the Snowball auto-extract feature to write arbitrary objects into other users' buckets, completely breaking multi-tenant isolation. The vulnerability chains three flaws: No ../ sanitization in tar entry key normalization; IAM wildcard matching uses raw (uncleaned) paths; and Filesystem path cleaning resolves ../ across bucket boundaries.

Vulnerability Title
RustFS 路径遍历漏洞
Vulnerability Description
rustfs是RustFS组织开源的一个高性能对象存储系统。 RustFS 1.0.0-beta.4版本存在路径遍历漏洞,该漏洞源于Snowball自动提取功能中存在路径遍历问题,涉及tar条目键规范化中缺乏../清理、IAM通配符匹配使用原始路径以及文件系统路径清理跨存储桶边界解析../,可能导致已认证用户将任意对象写入其他用户的存储桶。
