UTT HiPER 1250GW CVE-2026-7419: Remote Buffer Overflow Exploitable
A critical buffer overflow vulnerability, CVE-2026-7419, has been identified in UTT HiPER 1250GW devices running versions up to 3.2.7-210907-180535. According to the National Vulnerability Database, this flaw resides within the strcpy function in the route/goform/formTaskEdit_ap file. Manipulating the Profile argument can trigger the overflow, leading to remote code execution.
The National Vulnerability Database assigns this vulnerability a CVSSv3.1 score of 8.8 (High), highlighting its severity. The attack vector is network-based, requires low privileges, and has no user interaction, making it highly attractive to attackers. Crucially, an exploit for CVE-2026-7419 is publicly available, significantly increasing the immediate threat level for unpatched systems. Defenders should assume active exploitation is underway or imminent.
This isn’t just a theoretical vulnerability; it’s a direct path to device compromise. Attackers can leverage this to gain full control over affected routers, enabling them to intercept traffic, pivot into internal networks, or establish persistent backdoors. Given the public exploit, organizations using UTT HiPER 1250GW devices must prioritize patching and network segmentation to mitigate this severe risk.
What This Means For You
- If your organization uses UTT HiPER 1250GW routers, immediately verify your firmware version. Any device running up to 3.2.7-210907-180535 is vulnerable to CVE-2026-7419 and likely under active attack. Patch or isolate these devices now. Audit logs for unusual activity on network edge devices.
