Java vulnerability analysis and mitigation
Overview
JFinalCMS version 5.0.0 contains a directory traversal vulnerability that allows unauthenticated remote attackers to read arbitrary files via path traversal sequences (../) in the fileKey parameter of the /common/down/file endpoint. The vulnerability was discovered and disclosed on December 10, 2023 (NVD).
Technical details
The vulnerability exists in the file download functionality accessed through the /common/down/file route. The application fails to properly validate the fileKey parameter, allowing attackers to use path traversal sequences (../) to access files outside the intended directory. The vulnerability has been assigned a CVSS v3.1 base score of 7.5 HIGH (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is classified as CWE-22: Improper Limitation of a Pathname to a Restricted Directory (NVD).
Impact
This vulnerability allows unauthenticated remote attackers to read arbitrary files from the system via directory traversal. Since no authentication is required, any remote attacker can potentially access sensitive configuration files, credentials, or other confidential information stored on the server (Gitee Issue).
