A flaw has been found in UTT HiPER 810 firmware version 1.7.4-141218. The vulnerability lies in the strcpy function of the file /goform/setSysAdm, which causes a buffer overflow due to improper handling of the passwd1 argument. This vulnerability allows attackers to exploit the system remotely, making it critical for organizations to address this issue immediately.
With a CVSS score of 8.9, this vulnerability is classified as high severity. The implications of such a vulnerability are significant, as it not only affects the confidentiality, integrity, and availability of the system but also poses a risk of unauthorized access.
The exploit for this vulnerability is already published and may be utilized in attacks. Organizations operating the affected firmware should prioritize patching to mitigate possible exploitation.
Given the urgency of this vulnerability, organizations should address this issue in their priority patch cycle to prevent potential breaches and ensure the security of their systems.
Vulnerability Details
The vulnerability allows for buffer overflow due to manipulation of the argument passwd1 in the strcpy function. The CVSS score of 8.9 indicates a high level of risk, with a potential for significant damage, including loss of control over the affected system.
This vulnerability affects UTT HiPER 810 firmware version 1.7.4-141218 and has been officially documented. The publication date of this vulnerability is January 19, 2026.
Technical Analysis
The root cause of this vulnerability stems from the improper use of the strcpy function, which does not validate the length of the input. The attack vector for this vulnerability is network-based, requiring low complexity to exploit. No privileges are required, and user interaction is not necessary to trigger the exploit.
The potential impacts of this vulnerability include high confidentiality, integrity, and availability risks. If exploited, an attacker could gain unauthorized access to sensitive data or control over the affected device, significantly affecting organizational operations.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data and system control. The vulnerability's network exploitability adds to the severity, as attackers can target systems remotely without needing physical access. This increases the blast radius, especially for organizations with internet-facing devices.
The high CVSS score and potential for exploitation signify that organizations should prioritize remediation efforts immediately. Failure to address this vulnerability could result in significant operational disruptions and data breaches.
