CVE-2025-32982 is a high-severity vulnerability affecting NETSCOUT nGeniusONE versions prior to 6.4.0 b2350. The vulnerability is classified as a Broken Authorization Schema specifically within the report module of the product. This means that the authorization controls intended to restrict access to reporting functionalities are improperly implemented or missing, allowing unauthorized users to access sensitive report data without proper permissions. The CVSS 3.1 base score of 7.5 reflects a network attack vector (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is primarily on confidentiality (C:H), with no direct impact on integrity or availability. Since the vulnerability allows unauthenticated remote attackers to access sensitive information, it poses a significant risk of data leakage. The CWE-285 classification (Improper Authorization) confirms that the root cause is inadequate enforcement of access controls. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the data handled by nGeniusONE's reporting module make this a serious concern. NETSCOUT nGeniusONE is a network performance management and monitoring solution widely used by large enterprises and service providers to analyze network traffic and performance metrics. The report module typically contains detailed network usage statistics and potentially sensitive operational data, which if exposed, could aid attackers in reconnaissance or lead to privacy violations.

For European organizations, the impact of this vulnerability could be substantial. Many European enterprises and telecommunications providers rely on NETSCOUT nGeniusONE for network monitoring and diagnostics. Unauthorized access to the report module could lead to exposure of sensitive network topology, traffic patterns, and performance data. This information could be leveraged by threat actors to plan targeted attacks, including advanced persistent threats (APTs) or industrial espionage. Additionally, exposure of operational data may violate GDPR requirements concerning the protection of personal and sensitive data, potentially resulting in regulatory penalties and reputational damage. Critical infrastructure operators and large enterprises in sectors such as finance, energy, and telecommunications are particularly at risk, as they often deploy such monitoring tools extensively. The lack of requirement for authentication or user interaction increases the likelihood of exploitation, raising the urgency for European organizations to address this vulnerability promptly.

Given the absence of a publicly available patch at the time of publication, European organizations should implement compensating controls immediately. These include restricting network access to the nGeniusONE report module by implementing strict firewall rules and network segmentation to limit exposure to trusted administrative networks only. Employ VPNs or zero-trust network access solutions to control remote access. Monitor logs and network traffic for unusual access patterns to the reporting interfaces. Conduct thorough audits of user permissions and disable any unnecessary report module access. Organizations should also engage with NETSCOUT support to obtain information on upcoming patches or hotfixes and plan for rapid deployment once available. Additionally, consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts to the report module endpoints. Finally, raise awareness among network and security teams about this vulnerability to ensure rapid detection and response to potential exploitation attempts.
