CVE-2025-32983 is a high-severity vulnerability affecting NETSCOUT nGeniusONE versions prior to 6.4.0 b2350. The vulnerability allows an unauthenticated remote attacker to cause technical information disclosure through the exposure of stack traces. Specifically, the flaw is categorized under CWE-200, which involves the unintended exposure of sensitive information to unauthorized parties. In this case, the stack trace information can reveal internal application details, memory layout, or other diagnostic data that can aid attackers in further exploitation or reconnaissance. The CVSS v3.1 base score of 7.5 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). This means the vulnerability can be exploited remotely without authentication or user interaction, and the primary impact is the compromise of confidentiality through information leakage. Although no known exploits are currently reported in the wild, the ease of exploitation and the sensitive nature of the information disclosed make this a significant risk. NETSCOUT nGeniusONE is a network performance management and monitoring solution widely used in enterprise and service provider environments to monitor network traffic, performance metrics, and troubleshoot network issues. Exposure of stack traces could allow attackers to gain insights into the internal workings of the system, potentially facilitating further targeted attacks or reconnaissance activities.

For European organizations, the impact of this vulnerability can be substantial, particularly for those relying on NETSCOUT nGeniusONE for critical network monitoring and performance management. Disclosure of stack traces can reveal sensitive internal information such as software versions, configuration details, or memory addresses, which can be leveraged by attackers to craft more effective attacks, including privilege escalation or remote code execution exploits. Confidentiality breaches may expose proprietary network architecture details or sensitive operational data, potentially leading to industrial espionage or disruption of critical infrastructure. Given the role of nGeniusONE in monitoring telecommunications networks, financial institutions, and large enterprises, exploitation could undermine trust in network integrity and complicate incident response efforts. Although integrity and availability are not directly impacted by this vulnerability, the information disclosure alone can have cascading effects on organizational security posture and compliance with data protection regulations such as GDPR.

To mitigate this vulnerability, European organizations should prioritize upgrading NETSCOUT nGeniusONE to version 6.4.0 b2350 or later, where the issue is resolved. In the absence of an immediate patch, organizations should implement network-level access controls to restrict access to the nGeniusONE management interfaces, limiting exposure to trusted administrative networks only. Employing Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) with custom rules to detect and block anomalous requests that might trigger stack trace disclosures can reduce risk. Additionally, organizations should audit and harden logging and error handling configurations to ensure that stack traces or detailed error messages are not exposed externally. Monitoring network traffic for unusual access patterns to the nGeniusONE system and conducting regular vulnerability assessments can help detect exploitation attempts early. Finally, integrating threat intelligence feeds and maintaining awareness of any emerging exploits related to this CVE will enable timely response.
