CVE-2025-4526 is a medium-severity vulnerability identified in Dígitro NGC Explorer version 3.44.15, specifically affecting an unspecified part of the Configuration Page component. The core issue is the absence of password field masking, which means that passwords entered into the interface are displayed in plaintext rather than being obscured (e.g., with asterisks or dots). This vulnerability can be exploited remotely without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The lack of password masking can lead to inadvertent exposure of sensitive credentials to unauthorized parties, especially if network traffic or screen content is intercepted or monitored. Although the vulnerability does not directly allow credential theft or system compromise, it significantly increases the risk of credential disclosure through shoulder surfing, screen capture, or network sniffing if combined with other weaknesses. The vendor, Dígitro, was contacted but has not responded or issued a patch, leaving the vulnerability unmitigated. No known exploits are currently in the wild, but the ease of remote exploitation and the sensitive nature of password exposure make this a notable security concern. The CVSS 4.0 base score of 5.3 reflects a medium severity, primarily due to the confidentiality impact and the low attack complexity without user interaction.

For European organizations using Dígitro NGC Explorer 3.44.15, this vulnerability poses a risk of credential exposure that could lead to unauthorized access to critical systems. Since NGC Explorer is a network management and configuration tool, compromised credentials could allow attackers to manipulate network configurations, disrupt services, or pivot to other internal systems. The remote exploitability without user interaction increases the risk of automated scanning and exploitation attempts. Confidentiality is primarily impacted, but integrity and availability could be indirectly affected if attackers leverage exposed credentials to alter configurations or disrupt network operations. The lack of vendor response and patch availability prolongs the exposure window, increasing risk for organizations relying on this software. European entities in sectors such as telecommunications, utilities, and critical infrastructure that use Dígitro products are particularly vulnerable, as network management tools are high-value targets for attackers aiming to disrupt services or conduct espionage.

Given the absence of an official patch, European organizations should implement compensating controls immediately. These include restricting network access to the Dígitro NGC Explorer interface using firewalls and VPNs to limit exposure to trusted administrators only. Employ network segmentation to isolate management interfaces from general user networks. Enable monitoring and logging of access to the Configuration Page to detect suspicious activity. Use screen privacy filters and educate administrators about the risk of shoulder surfing or screen capture. Where possible, upgrade to a newer version of the software if available or consider alternative tools with better security practices. Additionally, enforce strong credential policies and multi-factor authentication on systems that integrate with NGC Explorer to reduce the impact of potential credential exposure. Regularly audit configurations and credentials stored or used by the software to detect anomalies promptly.
