CVE-2025-26063Public exploit

JavaScript execution via unsanitized nearby-network ESSIDs

Published Jul 31, 2025 · Updated Nov 3, 2025

Cross-site scripting in Intelbras RX1500 2.2.9 and RX3000 1.0.11 allows physically proximate attackers to execute JavaScript via a crafted ESSID. The Site Survey page inserts discovered network ESSIDs into nearby-network results without HTML encoding or semantic character filtering. Execution requires an administrator to scan for nearby networks and open or hover over the results, causing the script to run in the management interface.
