Technical Summary
A critical authentication bypass vulnerability exists in the Elber ESE DVB-S/S2 Satellite Receiver (versions 1.5.179 Revision 904, 1.5.56 Revision 884, and 1.229 Revision 440). The vulnerability allows unauthorized attackers to reset user passwords, including administrative accounts, by interacting directly with the set_pwd endpoint. This flaw can be exploited by sending a specially crafted request that modifies user credentials without requiring prior authentication.
The root cause of this vulnerability lies in the insecure implementation of the password management functionality, which lacks adequate authentication checks. Attackers can exploit this issue to gain full administrative control of the device, compromising system security and potentially disrupting satellite communication services.
Recommendations
- Apply Patches: Elber S.r.l. should release a security update to address the issue. Pending an official fix, organizations using affected devices should implement temporary workarounds.
- Network Segmentation: Restrict access to the management interface by placing the device behind a firewall and allowing access only from trusted IP ranges.
- Monitoring and Logging: Enable logging and monitoring to detect unauthorized access attempts. Organizations should actively analyze suspicious requests to the
set_pwdendpoint. - Access Controls: Implement additional layers of authentication, such as network-level authentication, to restrict access to sensitive functionality.
- Change Default Credentials: If possible, change the device’s default passwords to prevent unauthorized access even in the event that an attacker attempts to reset the credentials.
