Technical details
FUXA versions up to 1.1.12 contain a local file inclusion (LFI) vulnerability in the /api/download endpoint (CWE-98). The "name" parameter does not properly sanitize path traversal sequences (../, etc.), allowing an unauthenticated remote attacker to read arbitrary files from the server using a specially crafted request like /api/download?cmd=REPORT-DOWNLOAD&name=../../../../../../etc/passwd. No authentication is required and the attack is trivial to execute from the network. Successful exploitation allows an attacker to disclose sensitive files including system configuration, credentials, and application source code.
