Summary

CVE-2025-59410 is a medium-severity Missing Encryption of Sensitive Data (CWE-311) vulnerability in Linuxfoundation Dragonfly. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Vulnerability Data

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the code in the scheduler for downloading a tiny file is hard coded to use the HTTP protocol, rather than HTTPS. This means that an…

attacker could perform a Man-in-the-Middle attack, changing the network request so that a different piece of data gets downloaded. This vulnerability is fixed in 2.1.0.

MITRE ATT&CK Enterprise TechniquesAI

T1557 Adversary-in-the-Middle Credential Access
Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as [Network Sniffing](https://attack.
Why these techniques?

The vulnerability enables a Man-in-the-Middle (MitM) attack due to hard-coded HTTP usage for tiny file downloads in the P2P system, allowing attackers to intercept and modify network traffic to deliver malicious data.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires cryptographic mechanisms to protect the confidentiality and integrity of transmitted files, eliminating the hardcoded HTTP MITM exposure described in the CVE.

prevent

Mandates the use of organization-defined cryptography for data in transit, which would have prevented the scheduler from defaulting to unencrypted HTTP.

prevent

Requires protection of session authenticity during network exchanges, addressing the MITM risk when tiny-file downloads occur over HTTP.

PR.DS-01 mostly match
prevents

PR.DS-01 directly mandates encryption for data-at-rest and therefore prevents CWE-311 mostly for storage, yet the weakness also spans transmission and other contexts that this single at-rest control leaves unaddressed.

PR.DS-02 partial match
prevents

PR.DS-02 directly eliminates the transmission facet of CWE-311 via mandatory encryption but leaves the storage facet untouched, so each direction rates only partial.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Explicit rules requiring encryption for sensitive information in transit eliminate the weakness of sending data without cryptographic protection.

prevents

Explicitly calling for protection of data in transit and at rest, plus secure encryption of communications, drives the implementation of encryption that prevents clear-text exposure of sensitive information.
