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, specifically affecting the strcpy function in the route/goform/ConfigAdvideo file. The vulnerability arises from improper handling of the Profile argument, allowing remote attackers to cause a buffer overflow. The vulnerability affects version 3.2.7-210907-180535 and earlier. An exploit has been publicly released, increasing the risk of attacks. There is no confirmed patch or official remediation available at this time.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the strcpy function within the route/goform/ConfigAdvideo component of UTT HiPER 1250GW devices up to version 3.2.7-210907-180535. The flaw is triggered by manipulating the Profile argument remotely, leading to memory corruption. The vulnerability has a CVSS 4.0 base score of 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.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution or denial of service due to buffer overflow, compromising the confidentiality, integrity, and availability of the affected device. The public availability of an exploit increases the likelihood of attacks. The device's network exposure and lack of required privileges for exploitation heighten the risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting network access to the affected device and monitoring for suspicious activity related to the ConfigAdvideo function. Avoid exposing the device to untrusted networks where possible.
