CVE Alert: CVE-2025-11651 – UTT – 进取 518G

Risk verdict

High risk of remote code execution on the affected device due to a buffer overflow in a remotely accessible endpoint; exploitation is publicly disclosed, elevating urgency.

Why this matters

Successful exploitation could give an attacker full control of the device, enabling persistence, data exfiltration, or further network compromise. Organisations with exposed management interfaces may see rapid impact across endpoints, with potential disruption to services reliant on the device.

Most likely attack path

An externally reachable attacker could trigger the overflow by crafting inputs to the Profile argument in the formRemoteControl endpoint, with no user interaction required. The vulnerability suggests low-preconditions and remote access, raising the likelihood of rapid exploitation on any device with exposed management interfaces and weak network controls, potentially enabling high-privilege actions and lateral movement within the LAN.

Who is most exposed

Devices deployed in consumer or small business networks that expose web-based management to untrusted networks are most at risk; typical deployments include gateways or routers with WAN-accessible form interfaces.

Detection ideas

• Look for unusual, oversized requests targeting /goform/formRemoteControl, especially non-standard Profile values.
• Monitor for device crashes, memory corruption symptoms, or unexpected reboots/logs indicating a buffer overflow.
• Identify spikes in inbound management traffic from external sources or from unexpected subnets.
• Correlate with CVSS-exposed indicators: unusual authentication events or privilege escalation attempts.
• Inspect crash dumps or kernel logs for stack/heap corruption signatures.

Mitigation and prioritisation

• Apply vendor firmware update that contains the fix; if unavailable, disable remote management or restrict access to trusted networks only.
• Implement network access controls: allow management traffic only from whitelisted subnets, and enable MFA where applicable.
• Deploy endpoint/IDS signatures or WAF rules to detect and block malicious payloads targeting formRemoteControl.
• Plan a change window for firmware upgrade and conduct pre/post validation tests.
• If feasible, rotate credentials and review exposure of other web-management surfaces.
