A vulnerability was identified in UTT 进取 520W 1.7.7-180627. This affects the function strcpy of the file /goform/formFireWall. Such manipulation of the argument GroupName leads to buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability allows attackers to potentially gain control of affected systems.
With a CVSS score of 7.4, this vulnerability is classified as high severity. The risk to organizations includes potential unauthorized access and control over compromised devices. Given that the exploit is publicly available, organizations should prioritize patching immediately to mitigate the risk.
The urgency for defenders cannot be overstated. Organizations must take action to address this vulnerability in their systems, as attackers may leverage this flaw to execute malicious actions remotely.
Understanding the exploitability of this vulnerability is critical. Current intelligence indicates that no public exploit has been confirmed, but the nature of the vulnerability suggests that it could be weaponized by attackers.
Organizations should assess their exposure to this vulnerability and take appropriate steps to remediate it effectively.
Vulnerability Details
The vulnerability affects the UTT 520W firmware version 1.7.7-180627 and is characterized by buffer overflow due to improper handling of the GroupName argument in the strcpy function. The CWE classifications associated with this vulnerability include CWE-119 and CWE-120, both related to improper input validation leading to buffer overflow conditions.
The vulnerability was published on January 11, 2026, and has been analyzed by the vendor. The lack of response from the vendor following the disclosure raises concerns about their commitment to addressing security issues.
The CVSS v4.0 score of 7.4 indicates high severity, with various impacts on confidentiality, integrity, and availability categorized as high. Given the low attack complexity and the need for only low privileges to exploit, organizations are at significant risk.
Technical Analysis
The root cause of this vulnerability is a buffer overflow resulting from improper validation of input parameters in the strcpy function. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without direct access to the system.
The attack complexity is low, meaning that an attacker does not require specialized conditions to exploit this vulnerability. Additionally, the requirement for privileges is low, making it accessible to a wider range of potential attackers. User interaction is not necessary, which further increases the vulnerability's risk profile.
The impacts of this vulnerability are significant, with potential consequences for confidentiality, integrity, and availability categorized as high. Organizations must remain vigilant and monitor for any signs of exploitation.
Risk & Impact Analysis
Real-world deployment of the UTT 520W firmware poses significant risks for organizations due to the ease of exploitation. Attackers can leverage this vulnerability to gain control over networked devices, potentially leading to data breaches or disruptions in service.
The blast radius of this vulnerability is extensive, as it affects devices that may be widely deployed across various sectors. Organizations must understand the urgency of addressing this vulnerability, especially in light of the high CVSS score and the potential for exploitation.
Given that this vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog, organizations should take proactive measures to mitigate the risks associated with it before it potentially gains traction in the threat landscape.
