CVE-2023-48255Network attack vector

Session script execution via poisoned log

Published Jan 10, 2024 · Updated Jun 17, 2025

Cross-site scripting in Bosch Rexroth NEXO Cordless Nutrunner NEXO-OS V1000-Release through NEXO-OS V1500-SP2 allows remote attackers to run scripts. Malicious request content can poison a device log that later executes as client-side script when rendered, but Bosch does not identify the responsible handler or encoding failure. No authentication is required, but a victim must open the crafted URL or request or view the poisoned log; execution remains within that victim's session.
