HighCVSS 7.1Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
RustFS to rozproszony system przechowywania obiektów zbudowany w języku Rust. Przed wersją 1.0.0-beta.2, niewłaściwe autoryzowanie w operacji UploadPartCopy pozwalało na kopiowanie obiektów między kubełkami bez egzekwowania ograniczeń dotyczących dozwolonych źródeł kopiowania w kubełku docelowym.
Risk Assessment
Ta podatność umożliwia nieautoryzowany ruch danych między kubełkami, co może prowadzić do wycieku wrażliwych informacji i naruszenia polityki bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację do wersji 1.0.0-beta.2 lub nowszej, aby usunąć tę podatność oraz wdrożenie odpowiednich polityk bezpieczeństwa dotyczących zarządzania dostępem do kubełków.

Original NVD description (English source)
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, improper authorization in the UploadPartCopy operation allows copying objects across buckets without enforcing destination bucket restrictions on allowed copy sources. The implementation validates GetObject permission on the source bucket and PutObject on the destination bucket independently, but does not enforce any policy constraints on whether the destination bucket permits the specified copy source. This enables unauthorized cross-bucket data movement. This vulnerability is fixed in 1.0.0-beta.2.
