CVE-2025-8515 is an information disclosure vulnerability identified in Intelbras InControl version 2.21.60.9. The vulnerability arises from improper handling of requests to the JSON endpoint located at /v1/operador/. This flaw allows an attacker to remotely access sensitive information that should otherwise be protected. The vulnerability is classified as problematic but with a low severity score of 2.3 on the CVSS 4.0 scale, reflecting limited impact and difficulty in exploitation. The attack complexity is high, meaning that a successful exploit requires significant effort, expertise, or specific conditions. No user interaction or authentication is required, but the attacker must overcome the high complexity barrier. The vulnerability does not affect confidentiality, integrity, or availability to a significant degree, as indicated by the low impact metrics in the CVSS vector. Although the exploit has been publicly disclosed, there are no known active exploits in the wild at this time. Intelbras recommends upgrading the affected component to mitigate this issue, but no specific patch links are currently provided. The vulnerability primarily concerns information disclosure, which could potentially expose sensitive operational or configuration data from the InControl system, possibly aiding further targeted attacks if combined with other vulnerabilities or threat vectors.

For European organizations using Intelbras InControl 2.21.60.9, the direct impact of this vulnerability is limited due to its low severity and high exploitation complexity. However, any unauthorized information disclosure can pose risks, especially if the leaked data includes credentials, system configurations, or network details that could facilitate lateral movement or privilege escalation in a network. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, or critical infrastructure, may find even low-level information disclosure unacceptable. The vulnerability could also be leveraged as part of a multi-stage attack chain, increasing its potential impact indirectly. Given the remote attack vector and no requirement for user interaction, attackers could scan and target exposed InControl instances across networks. While no active exploitation is currently known, the public disclosure of the exploit code increases the risk of future attacks, especially if the vulnerability is not remediated promptly.

European organizations should prioritize upgrading Intelbras InControl to a version where this vulnerability is patched once available. In the absence of an immediate patch, organizations should implement network-level controls to restrict access to the /v1/operador/ endpoint, such as firewall rules or web application firewalls (WAF) with custom signatures to detect and block suspicious requests targeting this endpoint. Monitoring and logging access to this endpoint should be enhanced to detect any anomalous or unauthorized access attempts. Additionally, organizations should conduct regular vulnerability assessments and penetration tests focusing on InControl deployments to identify any exploitation attempts. Segmentation of the network to isolate InControl systems from general user networks can reduce exposure. Finally, maintaining up-to-date threat intelligence feeds and subscribing to Intelbras security advisories will help organizations respond quickly to any new developments or patches related to this vulnerability.
