Executive brief
FUXA is a web-based industrial control system (SCADA/HMI) visualization tool used for process monitoring and dashboard creation. A local file inclusion vulnerability allows unauthenticated attackers to read arbitrary files from the server by manipulating the file parameter, potentially exposing sensitive configuration files, logs, and application secrets without requiring authentication or user interaction.
Technical details
FUXA versions up to and including 1.1.12 contain a local file inclusion (LFI) vulnerability in the file parameter handling, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The vulnerability allows attackers to access arbitrary files on the server filesystem, including the fuxa.log file, by directly manipulating the file parameter in requests. The attack is network-accessible, requires no authentication or user interaction, and allows full confidentiality compromise through arbitrary file disclosure. No patch information is available in the advisory text, though users should upgrade to a version newer than 1.1.12 if available.
