What to do
AI-suggested
Organizations should immediately verify if Intelbras RX1500 routers are in use within their networks and identify the firmware version. 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.
Description
Intelbras RX1500 Router v2.2.17 and before is vulnerable to Incorrect Access Control in the FirmwareUpload function and GetFirmwareValidation function.
