3DescriptionNVD
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the admin router explicitly whitelists /profile/cpu and /profile/memory from the authentication layer, allowing any unauthenticated HTTP client to invoke profiling handlers without credentials. On supported builds (e.g., glibc), the handler invokes a fixed 60-second CPU profiling operation (dump_cpu_pprof_for(Duration::from_secs(60))). This may result in significant CPU resource consumption per request and can potentially lead to denial of service when abused. Additionally, the handler returns the server’s absolute filesystem path in the response body, resulting in information disclosure. This vulnerability is fixed in 1.0.0-beta.2.
AnalysisAI
Unauthenticated denial of service and information disclosure in RustFS distributed object storage prior to version 1.0.0-beta.2 allows remote attackers to repeatedly invoke profiling endpoints that the admin router whitelists from authentication. Each request triggers a fixed 60-second CPU profiling operation and leaks the server's absolute filesystem path in the response. …

RemediationAI
Within 24 hours: Identify all RustFS instances running versions prior to 1.0.0-beta.2 and confirm whether admin endpoints are reachable from untrusted networks. Within 7 days: Restrict network access to RustFS admin router to internal networks only; implement rate limiting on profiling endpoints. …
