CVE-2026-2935 Details
Description
A weakness has been identified in UTT HiPER 810G up to 1.7.7-171114. This issue affects the function strcpy of the file /goform/ConfigExceptMSN. Executing a manipulation of the argument remark can lead to buffer overflow. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.
A buffer overflow vulnerability has been identified in the UTT HiPER 810G router, affecting firmware versions through 1.7.7-171114. The issue arises in the ConfigExceptMSN interface, where the strcpy function is used to copy user-supplied data without proper length validation. This flaw allows authenticated attackers to send crafted requests that overflow the buffer, potentially leading to arbitrary code execution or causing the device to crash. The vulnerability can be exploited remotely, and a public proof-of-concept exploit is available.
Users are advised to upgrade to the latest firmware version provided by UTT. Additionally, implement strict input length validation for all user-supplied parameters and avoid using unsafe functions like strcpy, opting for safer alternatives instead.
