CVE-2025-67159 identifies a vulnerability in Vatilon version 1.12.37-20240124 where user credentials are transmitted in plaintext, exposing them to interception by attackers. The vulnerability falls under CWE-319, which concerns the cleartext transmission of sensitive information. The CVSS v3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates that the vulnerability can be exploited remotely over the network without any privileges or user interaction, resulting in a high impact on confidentiality but no impact on integrity or availability. The lack of encryption during credential transmission means that any attacker capable of network sniffing—such as those on the same local network or able to intercept traffic on transit paths—can capture usernames and passwords. This can lead to unauthorized access to user accounts and potentially further compromise of systems relying on these credentials. No patches or fixes are currently listed, and no known exploits have been reported in the wild, but the vulnerability’s nature makes it a critical risk if left unaddressed. Organizations using Vatilon should prioritize securing communication channels and monitoring for credential exposure.

The primary impact of this vulnerability is the compromise of user credentials, which can lead to unauthorized access to systems and data breaches. For European organizations, especially those in finance, healthcare, government, and critical infrastructure sectors, this could result in significant confidentiality losses, regulatory penalties (e.g., GDPR violations), and reputational damage. Attackers intercepting credentials can escalate privileges, move laterally within networks, and exfiltrate sensitive information. The vulnerability does not directly affect system integrity or availability but facilitates further attacks that can. Given the ease of exploitation and the high value of stolen credentials, the threat is substantial. Organizations relying on Vatilon or integrated systems transmitting credentials in plaintext are particularly vulnerable, and the absence of patches increases the risk window.

1. Immediately enforce the use of encrypted communication protocols such as TLS 1.2 or higher for all credential transmissions within Vatilon and related systems. 2. Conduct network traffic analysis to detect any plaintext credential transmissions and unauthorized sniffing attempts. 3. Rotate all potentially exposed credentials and enforce strong password policies combined with multi-factor authentication (MFA) to reduce the impact of credential compromise. 4. Implement network segmentation to limit exposure of sensitive traffic to untrusted networks. 5. Monitor logs and authentication attempts for anomalies that may indicate credential misuse. 6. Engage with Vatilon vendors or developers to obtain patches or updates addressing this vulnerability as soon as they become available. 7. Educate users and administrators about the risks of plaintext credential transmission and the importance of secure communication practices. 8. Consider deploying endpoint detection and response (EDR) solutions to identify lateral movement attempts following credential theft.
