Summary

CVE-2025-68705 is a critical-severity Path Traversal (CWE-22) vulnerability in Rustfs Rustfs. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly validates and sanitizes file path inputs to the /rustfs/rpc/read_file_stream endpoint, preventing path traversal exploitation.

prevent

Enforces strict access control policies to confine file reads within intended object storage directories, blocking unauthorized access via traversal.

prevent

Ensures timely patching of the specific path traversal flaw in affected RustFS versions, eliminating the vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

Path traversal in public RPC endpoint directly enables remote file read outside intended dirs (T1190 for initial exploitation of the exposed service; T1005 for resulting arbitrary local file access).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

RustFS is a distributed object storage system built in Rust. In versions 1.0.0-alpha.13 to 1.0.0-alpha.78, RustFS contains a path traversal vulnerability in the /rustfs/rpc/read_file_stream endpoint. This issue has been patched in version 1.0.0-alpha.79.

Deeper analysisAI

CVE-2025-68705 is a path traversal vulnerability (CWE-22) in RustFS, a distributed object storage system implemented in Rust. The issue affects versions 1.0.0-alpha.13 through 1.0.0-alpha.78 and resides in the /rustfs/rpc/read_file_stream endpoint. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its potential for severe impact across confidentiality, integrity, and availability.

A remote, unauthenticated attacker with network access can exploit this vulnerability with low complexity and no user interaction required. Exploitation enables high-impact effects, including unauthorized access to files outside the intended directory via path traversal in the read_file_stream endpoint, compromising system confidentiality, integrity, and availability.

The vulnerability has been addressed in RustFS version 1.0.0-alpha.79. Additional details on the patch and remediation are available in the GitHub security advisory at https://github.com/rustfs/rustfs/security/advisories/GHSA-pq29-69jg-9mxc and the fixing commit at https://github.com/rustfs/rustfs/commit/ab752458ce431c6397175d167beee2ea00507d3e.
