AlienVault OTX Malware

files-bucket-server

All versions of the package files-bucket-server are vulnerable to Directory Traversal where an attacker can traverse the file system and access files outside of the intended directory.

CVE-2025-8021 is a high-severity directory traversal vulnerability affecting all versions of the files-bucket-server package. Directory traversal vulnerabilities allow attackers to manipulate file path inputs to access files and directories outside the intended restricted directory. In this case, an attacker can craft requests to traverse the file system hierarchy, potentially reading sensitive files on the server that should be inaccessible. The vulnerability requires no authentication (PR:N) and no user interaction (UI:N), making it remotely exploitable over the network (AV:N) with low attack complexity (AC:L). The CVSS 4.0 score of 8.7 reflects the critical nature of this flaw, primarily due to the high confidentiality impact (VC:H) with no impact on integrity or availability. Since the vulnerability does not require privileges or user interaction, any exposed instance of files-bucket-server is at risk. The lack of patches or known exploits in the wild as of the publication date (July 23, 2025) suggests the vulnerability is newly disclosed. However, the ease of exploitation and potential to access sensitive system files pose a significant threat to organizations using this software. The files-bucket-server is typically used for file storage and management, so unauthorized access to files could lead to data breaches, leakage of credentials, configuration files, or other critical information stored on the server.
