Lifecycle Timeline
2DescriptionCVE.org
A vulnerability has been identified in the Acer System Monitoring component included with NitroSense and PredatorSense. A WebSocket service was configured to listen on all network interfaces, which may expose the service to unintended network access.
AnalysisAI
Acer System Monitoring, the WebSocket-enabled helper bundled with NitroSense and PredatorSense on Acer Nitro and Predator laptops, is configured to bind its listener to all network interfaces rather than to localhost, so any host that can reach the port on the same network segment can talk to the service without authentication or user interaction. The consequences are limited - the assessed impact is confined to low-level confidentiality, integrity and availability effects (minor telemetry exposure or restricted interaction with the service) - and the issue is compounded only mildly by the fact that the utility must actually be installed and running on a reachable machine. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the Acer System Monitoring component (shipped with NitroSense or PredatorSense) is installed and running, and that the attacker can reach the machine's WebSocket listening port over the network - realistically an attacker on the same LAN/adjacent network, since the flaw is the service binding to all interfaces (0.0.0.0) rather than localhost. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority issue and the signals are consistent about that. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis; the provided reference (https://community.acer.com/en/kb/articles/19879) is an Acer community knowledge-base article rather than a versioned security bulletin, so administrators should monitor it and Acer's product security channels for a NitroSense/PredatorSense update before assuming a fix is available. … Detailed patch versions, workarounds, and compensating controls in full report. |
