Vulnerability from github – Published: 2026-09-23 09:30 – Updated: 2026-09-23 09:30

Details

An unauthenticated local attacker can connect to the MQTT broker over its localhost WebSocket endpoint in Acer NitroSense software (versions up to and including 5.2.62). This allows the attacker to invoke exposed ddsc RPC functions, including child_process.execSync(), resulting in arbitrary command execution in the application context.

Severity

6.1 (Medium)
