CVE-2026-7420: Buffer Overflow in UTT HiPER 1250GW
CVE-2026-7420 is a high-severity buffer overflow vulnerability in the UTT HiPER 1250GW device up to version 3. 2. 7-210907-180535. The flaw exists in the strcpy function within the route/goform/ConfigAdvideo file, where manipulation of the Profile argument can cause a buffer overflow. This vulnerability can be exploited remotely without user interaction or privileges. Although a public exploit is available, there is no confirmed patch or official remediation at this time.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the strcpy function of the route/goform/ConfigAdvideo file in UTT HiPER 1250GW firmware versions up to 3.2.7-210907-180535. An attacker can remotely manipulate the Profile argument to trigger the overflow. The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and the device is not a cloud service, so remediation depends on vendor action.
Potential Impact
Successful exploitation can lead to buffer overflow, potentially allowing remote code execution or denial of service on the affected device. The vulnerability impacts confidentiality, integrity, and availability with high severity. The presence of a public exploit increases the risk of active attacks, although no confirmed exploitation in the wild has been reported yet.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict remote access to the affected device and monitor for suspicious activity related to the Profile parameter. Avoid exposure of the device to untrusted networks. Follow vendor communications closely for updates on patches or mitigations.
