UTT HiPER 1200GW Buffer Overflow (CVE-2026-7513) Exposes Remote Control
The National Vulnerability Database has disclosed CVE-2026-7513, a high-severity buffer overflow vulnerability impacting UTT HiPER 1200GW devices running firmware up to version 2.5.3-170306. This flaw, rated 8.8 CVSS, stems from improper handling of string copy operations within the strcpy function of the /goform/formRemoteControl file.
Attackers can exploit this remotely, potentially leading to arbitrary code execution or denial of service. The critical aspect here is that the exploit has been publicly disclosed, significantly lowering the bar for attackers. This isn’t theoretical; it’s an active threat that can be leveraged by anyone with basic skills.
For defenders, the implication is direct: any UTT HiPER 1200GW devices on your network, especially those exposed to the internet, are at high risk. The formRemoteControl function suggests a direct path to device compromise, bypassing traditional perimeter defenses if not properly segmented or patched. This is a classic CISO nightmare: a high-severity, remotely exploitable vulnerability with public exploit code.
What This Means For You
- If your organization uses UTT HiPER 1200GW devices, immediately identify all instances and check their firmware versions. Prioritize patching to a version beyond 2.5.3-170306. If immediate patching isn't possible, isolate these devices from the internet and implement strict network segmentation to limit potential attack paths.
