A vulnerability has been found in UTT 进取 520W 1.7.7-180627. The affected element is the function strcpy of the file /goform/formPolicyRouteConf. Such manipulation of the argument GroupName leads to buffer overflow. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
This vulnerability is classified as high severity with a CVSS score of 7.4, indicating significant risks to affected systems. Organizations using UTT 520W firmware should prioritize patching to mitigate potential exploitation.
Risk to organizations includes potential unauthorized access and system compromise due to the buffer overflow vulnerability. Attackers may leverage this vulnerability to execute arbitrary code and disrupt normal operations, leading to significant operational and reputational damage.
Organizations should prioritize patching immediately. The urgency is underscored by the public disclosure of the exploit and the potential for widespread exploitation by attackers.
Vulnerability Details
The specific vulnerability allows for buffer overflow via improper handling of the GroupName argument in the strcpy function. With a CVSS score of 7.4, this high-severity vulnerability poses a serious risk, as it can be exploited remotely without user interaction, requiring only low privileges to execute.
The affected product is the UTT 520W firmware version 1.7.7-180627. The vulnerability was published on February 6, 2026.
CWE classifications for this vulnerability include CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).
Technical Analysis
The root cause of this vulnerability lies in the improper validation of input to the strcpy function, which can lead to a buffer overflow. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without physical access to the device.
The attack complexity is low, meaning that the vulnerability can be exploited easily by attackers with minimal technical skills. The required privileges are low, as only a user with basic access to the system is needed to trigger the vulnerability.
No user interaction is required for the attack to be successful. The potential impacts include high confidentiality, integrity, and availability impacts, making this a critical vulnerability to address.
Risk & Impact Analysis
Real-world deployment risk is significant, especially for organizations using UTT 520W firmware within their networks. The potential for unauthorized access and system control emphasizes the need for immediate action.
The urgency for organizations to patch this vulnerability is high, given the CVSS score and the nature of the exploit. Failure to address this vulnerability could lead to severe consequences, including data breaches and operational disruptions.
