CVE Alert: CVE-2025-11652 – UTT – 进取 518G

Risk verdict

High risk and urgent: a publicly disclosed remote buffer overflow with a verified exploit path could enable remote code execution without user interaction.

Why this matters

The vulnerability yields full compromise of the affected device’s integrity, with potential for remote control, data exposure, and disruption of network services. In environments where exposed routers/gateways are reachable from the Internet, an attacker could pivot to adjacent devices, degrade availability, or exfiltrate sensitive traffic.

Most likely attack path

Remote attacker, no user interaction required, targets the vulnerable endpoint /goform/formTaskEdit_ap. The flaw stems from input handling (txtMin2) causing memory corruption with high-severity impact on confidentiality, integrity and availability. Exploitation relies on network access and low-privilege credentials (PR:L), but remote access is possible, enabling potential lateral movement within trusted segments once initial access is gained.

Who is most exposed

Devices in internet-facing deployments running this firmware, common in small business or consumer network appliances, are at highest risk; environments with exposed management interfaces or remote administration are especially vulnerable.

Detection ideas

• Look for anomalous requests to /goform/formTaskEdit_ap with crafted txtMin2 values.
• Unusual memory fault indicators, crashes, or reboot patterns on affected devices.
• Indicators from exploitation chatter or PoC signatures in IDS/IPS and log aggregations.
• Unusual privilege elevation attempts or unexpected process spawns post-request.
• Sudden spikes in outbound traffic or anomalous access to internal hosts.

Mitigation and prioritisation

• Apply vendor patch to the fixed version as a priority; verify deployment across all affected devices.
• Restrict or disable remote management to trusted networks; implement strong ingress controls.
• Deploy WAF/IPS rules to detect or block crafted requests targeting formTaskEdit_ap.
• Implement network segmentation and device hardening; ensure logging and alerting for AP-level failures.
• Schedule a change window for patch rollout and perform post‑patch validation.
