Technical Analysis

The vulnerability identified as CVE-2025-50405 affects Intelbras RX1500 Router firmware version 2.2.17 and earlier. It involves incorrect access control mechanisms within two critical firmware-related functions: FirmwareUpload and GetFirmwareValidation. These functions are responsible for managing firmware updates and validating firmware integrity, respectively. Improper access control in these functions could allow an attacker to bypass authentication or authorization checks, potentially enabling unauthorized firmware uploads or manipulation of firmware validation processes. This could lead to unauthorized code execution, persistent compromise of the router, or disruption of network services. Since routers are foundational network devices, exploitation could facilitate further lateral movement within a network or serve as a foothold for more extensive attacks. The absence of a CVSS score and public exploit reports suggests the vulnerability is newly disclosed and may not yet be widely exploited, but the nature of the flaw indicates a significant security risk if left unmitigated.

Potential Impact

For European organizations, the exploitation of this vulnerability could have severe consequences. Intelbras RX1500 routers, if deployed within corporate, governmental, or critical infrastructure networks, could be compromised to allow attackers to install malicious firmware, leading to data interception, network disruption, or use of the device as a launchpad for attacks against internal systems. This could impact confidentiality by exposing sensitive communications, integrity by altering network traffic or device configurations, and availability by causing denial of service. Given the router's role in network perimeter defense, successful exploitation could undermine trust in network security and lead to regulatory compliance issues under frameworks such as GDPR, especially if personal data is exposed or network integrity is compromised.

Mitigation Recommendations

Organizations should immediately verify if Intelbras RX1500 routers are in use within their networks and identify the firmware version. Since no patch links are currently available, it is critical to monitor Intelbras communications for firmware updates addressing this vulnerability. In the interim, restrict access to router management interfaces to trusted administrative networks only, implement network segmentation to limit exposure, and enforce strong authentication mechanisms. Additionally, enable logging and monitoring for unusual firmware upload attempts or unauthorized access patterns. Where possible, consider deploying network intrusion detection systems (NIDS) to detect anomalous traffic indicative of exploitation attempts. Finally, prepare an incident response plan specifically for network device compromise to enable rapid containment and remediation.
