Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was detected in UTT HiPER 1200GW up to 2.5.3-170306. This affects the function strcpy of the file /goform/formTaskEdit. The manipulation results in stack-based buffer overflow. The attack may be launched remotely. The exploit is now public and may be used.
AnalysisAI
Stack-based buffer overflow in UTT HiPER 1200GW routers (firmware versions up to 2.5.3-170306) allows remote authenticated attackers to corrupt memory via the strcpy function in the /goform/formTaskEdit endpoint. Publicly available exploit code exists, raising the practical risk despite the requirement for low-level privileges. No KEV listing or EPSS data is provided in the input, so widespread automated exploitation has not been confirmed.
Technical ContextAI
The affected product (cpe:2.3:a:utt:hiper_1200gw) is a small-business/SOHO gateway router manufactured by UTT Technologies. The flaw is classified as CWE-121 (Stack-based Buffer Overflow), rooted in the use of the unsafe strcpy() C library function inside the formTaskEdit handler of the device's web management interface (/goform/ path is typical of embedded Boa/GoAhead-style web servers). Because strcpy() performs no bounds checking on the destination buffer, attacker-supplied input copied from an HTTP form field overruns the fixed-size stack buffer, overwriting saved return addresses and potentially enabling control-flow hijack on the MIPS/ARM firmware typical of these devices.
RemediationAI
No vendor-released patch identified at time of analysis - UTT has not published a fixed firmware version in the available references. As compensating controls, restrict access to the router's web management interface to a trusted management VLAN or admin workstation by binding the HTTP/HTTPS admin service to LAN-only and explicitly disabling WAN-side administration (side effect: remote admin convenience is lost). Replace default and weak administrator credentials with strong unique passwords to raise the bar against the PR:L requirement, and place the device behind an upstream firewall blocking inbound TCP 80/443/8080 to the device from the internet. Monitor https://vuldb.com/vuln/367585 for vendor firmware updates and consider device replacement if UTT does not issue a fix, since end-of-life SOHO routers commonly remain unpatched.
