Detailsinfo

A vulnerability was found in dragonflyoss Dragonfly up to 2.0.x. It has been rated as problematic. This issue affects an unknown code. The manipulation with an unknown input leads to a weak hash vulnerability. Using CWE to declare the problem leads to CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). Impacted is integrity. The summary by CVE is:

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the DragonFly2 uses a variety of hash functions, including the MD5 hash, for downloaded files. This allows attackers to replace files with malicious ones that have a colliding hash. This vulnerability is fixed in 2.1.0.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2025-59354 since 09/12/2025. The exploitation is known to be difficult.
