Detailsinfo

A vulnerability, which was classified as problematic, has been found in dragonflyoss Dragonfly up to 2.0.x. This issue affects some unknown functionality. The manipulation with an unknown input leads to a permission assignment vulnerability. Using CWE to declare the problem leads to CWE-732. The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, DragonFly2 uses the os.MkdirAll function to create certain directory paths with specific access permissions. This function does not perform any permission checks when a given directory path already exists. This allows a local attacker to create a directory to be used later by DragonFly2 with broad permissions before DragonFly2 does so, potentially allowing the attacker to tamper with the files. 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-2025-59349 since 09/12/2025. The exploitation is known to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.
