CVE Alert: CVE-2025-11323 – UTT – 1250GW

Risk verdict

High risk: remote buffer overflow with public exploit guidance could enable unauthorised code execution on exposed devices.

Why this matters

The vulnerability provides network access to the device with low privileges and full impact on confidentiality, integrity and availability. Attackers could compromise the router, exfiltrate data, alter configurations or disrupt services, then pivot to adjacent devices or networks.

Most likely attack path

Exploitation can occur over the network without user interaction, but requires an existing low-privilege account on the device. An attacker could trigger the overflow via the vulnerable /goform/formUserStatusRemark path, gain control, then attempt persistence or lateral movement within vulnerable networks.

Who is most exposed

Devices with internet-facing or broad LAN management interfaces in SMB/enterprise deployments are most at risk, especially routers or gateway units shipped with this component family.

Detection ideas

• Logs show crashes or kernel/user-space memory corruption tied to formUserStatusRemark activity.
• Unusual or long Username payloads appearing in requests to /goform/formUserStatusRemark.
• Signs of unexpected device reboots, service outages, or degraded performance following network access attempts.
• IDS/IPS alerts for known exploit payload patterns or abnormal buffers in router management traffic.
• Authentication/login attempts preceding unusual remote activity on the device.

Mitigation and prioritisation

• Apply vendor patch or upgrade to a fixed firmware release; validate compatibility and rollback plan.
• Disable or restrict remote management; enforce VPN-only administration and strict access controls.
• Implement network segmentation and firewall rules to block access to the vulnerable endpoint from untrusted networks.
• Monitor and alert on attempts to access /goform/formUserStatusRemark; tune logging to capture overflow indicators.
• Change management: schedule a firmware update window; communicate impact and rollback procedures; verify post-update functionality. If KEV or EPSS data become available indicating active exploitation, treat as priority 1.
