CVE-2025-8515 identifies a security weakness in Intelbras InControl version 2.21.60.9, specifically within the JSON endpoint located at /v1/operador/. This endpoint processes JSON requests related to operator functions. The vulnerability allows an attacker to remotely manipulate requests to this endpoint to disclose sensitive information. The exact nature of the leaked information is unspecified but typically could include configuration data, user details, or operational parameters. Exploitation does not require user interaction and can be performed remotely over the network, but it requires low privileges and is rated as having high complexity, indicating that successful exploitation demands significant technical skill or specific conditions. The CVSS 4.0 vector (AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) reflects a network attack vector with high attack complexity, no user interaction, and low impact on confidentiality only. No integrity or availability impacts are noted. Although an exploit has been publicly disclosed, no widespread exploitation has been observed in the wild. Intelbras has advised upgrading the affected component to remediate the vulnerability, but no direct patch links are provided in the source. The vulnerability is classified as low severity due to limited impact and difficult exploitability.

For European organizations, the primary impact of CVE-2025-8515 is unauthorized disclosure of potentially sensitive information managed by Intelbras InControl systems. This could lead to exposure of operational details or user data, which may facilitate further targeted attacks or privacy violations. However, the low severity and high complexity reduce the likelihood of widespread exploitation. Organizations relying on Intelbras InControl for network or security management should be aware that attackers with network access and some privileges could leverage this flaw to gain intelligence about the system. This could be particularly concerning for critical infrastructure or enterprises with sensitive operational environments. The lack of impact on integrity or availability means system operations are unlikely to be disrupted directly by this vulnerability. Nonetheless, information disclosure can have cascading effects on security posture and compliance with data protection regulations such as GDPR.

1. Apply vendor-provided updates or patches for Intelbras InControl as soon as they become available to address CVE-2025-8515. 2. Restrict network access to the /v1/operador/ JSON endpoint by implementing firewall rules or network segmentation to limit exposure to trusted administrators only. 3. Enforce strict access controls and monitor logs for unusual or unauthorized access attempts to the management interface. 4. Use network intrusion detection systems (NIDS) to detect anomalous JSON requests targeting the vulnerable endpoint. 5. Conduct regular security assessments and penetration testing focused on Intelbras InControl deployments to identify any exploitation attempts. 6. Educate system administrators about the vulnerability and encourage prompt reporting of suspicious activity. 7. If possible, disable or limit the functionality of the affected endpoint until a patch is applied. These steps go beyond generic advice by focusing on network-level restrictions, monitoring, and operational controls tailored to the specific vulnerable component.
