CVE-2026-42949 Details
Description
A authorization bypass vulnerability exists in the /api/runscript functionality of FUXA (version(s): 1.3.2-2809). A specially crafted HTTP request can lead to execute priviledged operation. An attacker can make an unauthenticated HTTP request to trigger this vulnerability.
An authorization bypass vulnerability has been identified in the FUXA web-based HMI software, specifically in version 1.3.2-2809. The vulnerability resides within the '/api/runscript' endpoint, where improper authorization allows unauthenticated users to execute privileged operations. This is achieved by sending a specially crafted HTTP request that exploits the flaw in how the API validates user permissions before executing requested scripts.
The vendor has stated that the execution path will be updated to bind execution to the server-side script resolved by ID, preventing client-supplied names from altering the authorized execution target. This fix will be included in the next hotfix release.
