CVE-2024-24024Network attack vector

Arbitrary file read via attacker-controlled download path

Published Feb 8, 2024 · Updated Aug 19, 2024

Path traversal in xxyopen Novel-Plus 4.3.0-RC1 and earlier allows remote attackers to read arbitrary server files. FileController.fileDownload uses attacker-controlled filePath and fieName parameters to select and return a file without a documented path restriction. No authentication or user interaction is required, and successful requests disclose files readable by the application process.
